Figure 2: ICS-2003 Front-Panel Controls and Indicators

Display Screen

The display screen is divided into five areas, or windows. These include the talk, listen, answer-back, message, and symbol areas/windows.

Figure 3: ICS- 2003 Display Screen

Talk Window

The talk window is located directly above the selectors, and shows the currently assigned labels. Assigned labels are accessed when the selector is pushed or latched in the “talk” position (down). Each selector can be assigned as many as four labels. Each label can represent a talk path to a station, interface, fixed group, or party line, or can activate a programmable control function.

Answer-back window Symbol window

Ear icon

Message windowListen window


Listen Window

The listen window is located directly above the talk window. It contains one listen label per selector. Labels refer to the listen paths that are established when the selector is pushed up.

Answer-Back Window

The answer-back window is located above the “Answer Back” selector. It displays a list of as many as five incoming calls. The first caller’s label is closest to the “Answer Back” selector and is highlighted. Subsequent calls are placed to the right of the first in the window. This list is called the answer-back stack.

Message Window

The message window displays station status and error messages.

Symbol Window

The symbol window displays two graphic symbols. The functions of the two symbols are as follows:

• Ear symbol—indicates when someone is listening to (monitoring) the station.

• Window-indication symbol—displays a W (for window) and a Roman numeral I or II to indicate which talk/listen window is active, as toggled by the “Swap” button (See “Swap Button (9)” on page 1-12.).

Communication-Error Indicator

If the station should lose data communication with the matrix frame:

• It will display the message “WAITING FOR ECLIPSE CONNECTION.”

• All of the red LEDs will flash slowly.

When data communication is restored, the station will automatically return to normal operation.

Speaker/Headset Level Controls

To adjust the speaker or headset volume, use the “Intercom” and “Program” volume controls. The speaker volume can also be affected by three software-controlled functions: Page Override, Mute Level, and Listen Level Adjustment.

Intercom Volume

The “Intercom” volume control sets the overall level of all signals coming from the matrix frame.

Program Volume

The “Program” volume control adjusts the volume of the signal coming into the station through the auxiliary input of the “Miscellaneous” rear-panel connector.


Page Override

Page override is a special function in the station in which the intercom volume defaults to a preset to a value when commanded to by the central matrix. Any fixed group can be assigned the page-override function through the configuration program.

The configuration program determines preset value for each station. If the preset value is lower than the setting of the front-panel volume control, the volume will be controlled by the front-panel control.

Mute Level

This turns down the speaker level when any talk is active at the station. The amount of muting (measured in dB) is set by the configuration program for each station. This function helps prevent possible feedback. The maximum amount of muting is 15 dB below full volume. If the front panel control is set below that level, then muting will have no effect.

Listen Level Adjustment

The level of any active listen path can be adjusted individually. Refer to “Listen-Level Mode” on page 1-8.

Headset Connector

The headset connector provides a front-panel connection for a headset. Plugging in a headset will initially cause the station to switch to headset-microphone operation and will turn the speaker off. Unplugging the headset will cause the station to switch to panel-microphone operation and will turn the speaker on.

Talk/Listen Selectors and Indicators

The following section describes the operation of the talk/listen selectors and their associated indicators.

Selector Operation

The selectors operate as both talk and listen selectors; they also work as volume controls when the station is in listen-level mode (see “Listen-Level Mode” on page 1-8). Pressing a selector down accesses a talk label; pushing it up accesses a listen label. Pushing the talk selector down and quickly releasing it will “latch” the selector and the talk path will stay active until it is pressed again. Pressing and holding a talk selector causes the talk path to stay active only for as long as it is held down. Listen selectors operate in the same manner.

To prevent the selector on the station from latching in the talk position (local latch disable), or to prevent any station from latching a talk to the station (global latch disable) use the configuration program.

Talk and Listen Indicators

When a talk path is active, the selector’s red LED lights continuously. When a listen path is active, the selector’s green LED lights continuously.


Monitoring/Eavesdropping Indicators

If any other station begins monitoring a station a beep (the monitoring-alert tone) will sound at the station.

To inhibit the monitoring-alert tone, use the configuration program.

Call-Waiting Indicator

If a station calls another station with a selector programmed with the caller’s label, the red LED will flash rapidly. This flashing is a call-waiting tally. To answer the incoming call, push the indicated talk selector. The call-waiting tally will be cleared when the call is answered or after the call is terminated and the answer-back, auto-clear time out lapses.

Regardless of whether a selection is programmed with a caller’s label, the label will be placed in the answer-back stack (see “Removing Labels from the Answer-Back Stack” on page 1-7).

In-Use Tally Indicator

If a selector is assigned to a label and another station is currently using that label, the LED will double-flash once per second to indicate the label is in use. This tally must be enabled from the configuration software.

Telephone Off-Hook Tally Indicator

When a telephone interface is assigned to a talk selector, the talk LED will flash once per second if that telephone is off the hook. This tally must be enabled from the configuration program.

Radio Receiver Active Tally Indicator

When a two-way radio interface port is assigned to a talk selector, the LED will flash once per second when that radio’s receiver is active. This tally must be enabled from the configuration program.

Station Connected Tally Indicator

This tally is used when a station is connected to the frame by a high-speed data line (such as an ISDN or T1 line) that might be inactive periodically. The red LED of any talk selector associated with that station will flash once per second when the station is on-line. This tally must be enabled from the configuration program.

Audio Presence Tally Indicator

When a label is assigned to a listen selector, the LED will flash once per second to indicate someone is talking on that channel. This tally must be enabled from the configuration program.


Answer-Back Facility

The primary function of answer-back facility is to answer or call other stations or interfaces not assigned to a station’s selectors. Stations and interfaces that are assigned to a station’s selectors also can be answered or called with the answer-back facility.

The following sections describe the use of the answer-back facility.

Answer-Back Window

The answer-back window is located above the “Answer Back” selector. It displays a list of as many as five incoming calls. The first caller’s label is closest to the “Answer Back” selector and is highlighted. Subsequent calls are placed to the right of the first in the window. This list is called the answer-back stack.

Answer-Back Selector

The “Answer Back” selector answers calls from stations and interfaces that are both assigned and unassigned to the station.

When a call arrives from a station or interface:

• The calling station’s label will be placed in the answer-back stack and be highlighted in the answer-back window.

• The red LED will flash.

These two conditions will continue until the call is answered, or until the answer-back time-out period lapses and the caller’s label is automatically removed. To answer the call, push the “Answer Back” selector. The LED will stay on steady, indicating an active talk path to the caller. The talk path is active for as long as the selector is held.

Note: The “Answer Back” selector cannot be latched; it is a momentary-only function.

Calls from stations or interfaces assigned to station selectors will also be indicated by their associated LEDs.

Answer-Back Label Selection

If another call or calls comes in while using the answer-back selector:

• The user will hear the caller’s voice

• The label will be placed in the answer-back stack.

To answer the next caller:

1. Push up on the “Answer Back” selector to highlight the desired label in the answer-back stack.

2. Once the desired label is highlighted, press the selector down to talk.


Removing Labels from the Answer-Back Stack

Any label will be automatically removed from the stack if it is not answered within a certain time interval, which is set by the answer-back auto-clear time in the configuration program.

To manually remove the current caller’s label from the answer-back stack, push up on the “Answer Back” selector.

Calling an Unassigned Station

To call a destination in the answer-back stack:

1. Push up on the “Answer Back” selector to highlight the desired label in the answer-back stack.

2. Once the desired label is highlighted, press the selector down to talk.

Keypad: Single-Function Buttons

The first column of buttons on the keypad consists of:

• “Mic On/Off”

• “Speaker On/Off”

• “Mic Select”

1. Push (for less than 1 second) and quickly release the “Listen Level” button.2. “Listen Level Adjust Mode” will appear in the message window to indicate the

function is on and the LEDs of all active listen selectors will begin to flash.

Note: Only active selectors can be adjusted in listen-level mode.

3. Use the selector associated with the intended label to increase (up) or decrease (down) the volume.

4. To exit, push the “Listen Level” button or wait for the 3 second time-out.

Listen Level Reset

To reset the Listen Level to default settings:

1. Press (for less than 1 second) and quickly release the “Listen Level” button.2. Press and hold the “Listen Level” button for 3 seconds.3. Release the “Listen Level” button.

Call Signals

To activate a call signal push and hold (for at least 1 second) the “Listen Level” button until the station indicates it is in “Call Signal” mode.

The call signal will be sent each time the selector with that label assignment is pushed down and will remain so until the call-signal mode times out (about 5 seconds).

Call signals can be issued to any talk label assigned to a station’s talk/listen selectors. If more than one label is assigned to a selector, all labels will receive the signal. If a label is a fixed group, the entire group will receive the call signal. If the label is a party line, then every station listening on the party line will receive the call signal.

Remote Telephone Line Release

This function is available only if specifically enabled in the configuration program. To hang up a telephone interface left off the hook:

1. Push and hold the “Listen Level” button for at least 1 second to activate the call-signal mode.

2. While holding the “Listen Level” button, press the talk selector of the desired telephone’s label.

3. Release the “Listen Level” button.

Note: In addition to hanging up the telephone interface, this will deactivate any talk/listen selector set to the interface from anywhere in the system.

Listens Button (5)

Although not marked for the listen function, the center button (5) displays listen labels on any display expansion panel (XPL-12 or XPL-22) connected to the station. Momentarily pressing and quickly releasing the (5) button will cause all XPL panels to display the listen labels assigned to the selectors. If the listen and talk labels are the same, then there will be no change. The function will time-out after 10 seconds.

Swap Button (9)

The station can support two sets of talk and listen label assignments for its selectors. The Swap window (9) button alternates between the two sets; the talk/listen windows display the labels for each. This effectively doubles the selectors.

If talk/listen paths are latched on when windows are swapped, the paths will be disconnected temporarily. When the windows are swapped back, the previously latched paths will be re-established. Should the label appear in both windows (not necessarily in the same position) the path will remain latched through the swap.

Additionally, the station can be programmed to allow talks and listens to be active in both windows simultaneously.

This function can be inhibited from the configuration program.


Dial Button (*)

The “Dial” phone button turns the station keypad into a touch-tone phone keypad, allowing DTMF tones (Touch Tones) to be generated for telephone dialing. To place a telephone call:

1. Push a talk selector assigned to a telephone interface.2. After the dial tone is heard, push the “Dial” phone button on the keypad.3. Enter the phone number using the keypad buttons. The station will

automatically exit dial-tone mode after 5 seconds of keypad inactivity.4. While the call is in progress, it is possible to enter dial-phone mode and send

DTMF tones to the destination.

This function can be inhibited from the configuration program.

SA (Studio/Stage Announce) Button (#)

This button functions only if the station is equipped with the OPT-100 Auxiliary Audio Input/Output option. Pressing and holding the “SA” button sends the microphone output to the studio announce output on the Auxiliary Audio I/O connector. All other talk paths from the station to the matrix frame are turned off.

REAR-PANEL CONNECTORSThis section describes only those rear-panel functions directly affecting normal station operation. These include the functions available through the “Miscellaneous” connector and those added by the use of the “OPT-100 Auxiliary Audio” connector. The actual functions these inputs and outputs perform depend on the installation of the individual station. This section only describes the general use of these functions.

Miscellaneous Connector

The Miscellaneous connector includes the following functions:

• Logic input #1

• Logic input #2

• Programmable relay

• Mute relay

Logic Input #1 and #2

Each input can control one of several functions, determined through the configuration program. Typically, these inputs are connected to an external foot switch, a panel-mounted switch, or the logic output of another device.

The following functions are available:

• Mic On/Off—toggles the station’s microphone on and off.

• Mute Mic Output To Frame—turns off the audio from the station to the frame. It does not turn off the Hot Mic output (described in “OPT-100 Auxiliary Audio Option” on page 1-15).


• Mic Off —momentarily turns off the station’s microphone.

• Answer Back Talk/Clear—functions the same as the station’s “Answer Back” selector. Holding down the switch activates a talk to a label in the answer-back stack. To clear the label, quickly press and release the switch.

• Studio Announce—sends the output of the station’s selected microphone (panel or headset) to the station’s Studio Announce (SA) audio output, and activates the SA relay. The microphone output is not sent to the frame. The SA output and relay are only present if the station has the OPT-100 Auxiliary Audio I/O Option installed. (The SA options are described in “OPT-100 Auxiliary Audio Option” on page 1-15).

• Speaker OFF—turns off the station speaker, disabling all audible output from the station.

• PTT: Activate All Talk Keys—implements a push-to-talk function for all talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active talk selectors operate normally regardless of the PTT status. This input only controls latched talks.

• Activate Talk Switch #1— equivalent to pressing the station’s first (leftmost) talk selector; a momentary and latching activation.

• Activate Talk Switch #2—equivalent to pressing the station’s second talk selector; a momentary and latching activation.

• Activate Listen Labels Button—equivalent to pressing the “Listen Labels” button to display listen labels on any display expansion panel (XPL-12 or XPL-22) connected to the station.

• PTT: Activate Two-Way Radio Keys—implements a push-to-talk function for all two-way radio talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active two-way radio talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active two-way radio talk selectors operate normally regardless of the PTT status. This input only controls latched talks.

Programmable Relay

Each ICS-2003 station includes a relay controlled by the system program and independent of the local station function. This relay can be assigned to any label(s) in the system, which will activate whenever a talk or listen is set to that label(s). If activating the relay is the only action desired, assign the relay to a Control label. See the Eclipse Configuration System Manual for more details.

The relay can activate an external device, such as an applause light in a studio, a cue light, or a security door lock. Any programmable relay in the system can be activated from any station in the system, including a direct-inward-access caller.


Mute Relay

The mute relay is activated whenever any talk selector is activated at the station. The mute relay is commonly wired such that whenever it is activated, the volume of the monitor speaker in that room is decreased (muted).

OPT-100 Auxiliary Audio Option

The OPT-100 Auxiliary Audio option provides the following features:

• Hot Mic output

• SA audio and relay outputs

• Auxiliary audio line level output

Hot Mic Output

The Hot Mic output is a balanced, line-level, transformer-isolated feed of the signal from the currently selected microphone (panel or headset). The Hot Mic output is active regardless of whether the station has talk paths set and regardless of the front-panel’s control settings.

Studio/Stage Announce Audio and Relay Outputs

The SA output is a balanced, line-level, transformer-isolated feed with the same signal sent to the Hot Mic output, except it is only active when the SA button on the station’s front panel is pressed or when activated by Logic Input #1 or #2, which is configured for the Studio Announce Function.

Auxiliary Audio Line Level Output

The Auxiliary Audio Line Level output is a balanced, line-level, transformer-isolated feed of the input to the station’s internal speaker. For example, this output could be used to feed an external amplifier connected to loudspeakers.

EXPANSION PANEL OPERATIONOptional expansion panels provide additional selectors that operate the same as a station’s selectors, including talk, listen, tally, and error indication.

The XPL-12 expansion panel provides 10 additional keys, while the XPL-22 provides 20 additional keys. Each expansion panel offers illuminated 5-character labels for every key.

Only one rack unit (1RU) of a standard Electronics Industry Association equipment rack is required for each expansion panel. The panels’ compact size makes them ideal for use in TV control rooms, edit suites, mobile OB vans, and any other location where many talk/listen keys are necessary but space it at a premium.

Although the center button (5) on the station’s keypad is not marked for a function, it has the function of displaying “listen” labels on any display expansion panel (XPL-12 or XPL-22) connected to the station. Momentarily pressing and quickly releasing the “5” button will cause all XPL panels to display the listen


label assigned to the key. If the listen and talk labels are the same, then there will be no change. The function will time-out after 10 seconds.


INSTALLATION

INTRODUCTIONThis chapter describes the installation of the ICS-2003/ICS-2003T display station, including:

• Station placement

• Wiring

• Mains AC power

• Adjustments

• Configuration

• Accessory panels

MOUNTING STATIONSLocate all intercom stations at comfortable heights for operation and leave at least 2 inches (51 mm) of clearance behind the rear of the station’s chassis to allow for cable connectors.

Accessory panels, that are intended to expand or enhance station operation are usually mounted next to or near the station with which they are associated. Leave at least 2 inches (51 mm) of clearance behind the rear of the station to allow for cable connectors.

Accessory panels can be located as far as 25 ft. (7.6 m) away from the station. A 6-ft. (1.8 m) cable is supplied to connect them.

WIRINGThis section provides detailed wiring diagrams for all stations’ wiring systems.

Eclipse uses either a twisted, 4-pair transmission, a single-pair twisted, or a coax scheme between the station and the frame using the industry standard RJ-45 connector. Refer to Installing an Eclipse Matrix System: An Overview for RJ-45 connector installation and use, and the type of cable needed for connection between stations and frames.

Most stations have a DB-15M and an RJ-45 connector to connect them to the frame. Stations with only a DB-15M connector include a kit containing one DB-15F/RJ-45 adapter. The adapter allows the use of RJ-45 connectors on both ends of the connection between the frame and the station.

Connections to external devices via the Miscellaneous connector, use the included DB-15M connector to construct one or more cables to connect external devices to the station.

Leave at least 2 inches

(51mm) of clearance behind

the station for connecting

cables.

The following sections describe connecting the station to the matrix frame, and all the connections between the station and local devices. Each of the following sections describes cable and station connector wiring:

• Analog matrix frame to station wiring

• Digital matrix frame to station wiring

• Matrix station Miscellaneous connector wiring

• OPT-100 Auxiliary Audio I/O option

• Binaural headset wiring

ANALOG MATRIX FRAME TO STATION WIRINGThe analog audio RS-422 data communications module (COM-10) uses a 4-pair wiring scheme between the frame and stations. This module requires an MVX-A16 card in the frame.

Although some Matrix Stations have a DB-15M (male) connector for connection to the Matrix frame, most have a built-in RJ-45 connector. For those stations with a DB-15 male connector, Vitec Group Communications provides a properly wired DB-15F (female) to RJ-45 adapter for direct connection with RJ-45 terminated cables. Additionally, stations configured for digital communication are equipped with a BNC.

Four-pair analog wiring is typically wired with shielded CAT5 RJ-45 cable.

• Pair 1 transmits analog audio from the matrix port to the station.

• Pair 2 transmits RS-422 data from the station back to the matrix card port.

• Pair 3 transmits analog audio from the station to the matrix card port.

• Pair 4 transmits RS-422 data from the matrix port back to the station.

DIGITAL MATRIX FRAME TO STATION WIRINGThe ICS-2003T differs from the ICS-2003 because it contains an internal digital audio/data communications module (COM-20) that works in conjunction with the DIG-2 digital interface module to connect digital stations to the matrix.

The DIG-2 digital interface module offers two options for wiring the frame to intercom stations. One option is a single pair of double shielded (braid and foil) 24 AWG conductor CAT-6 Enhanced STP cable with RJ-45 connectors.

The second option, available because only one pair is required, is 75-ohm (RG59) braid shielded coax cable. For this option, a BNC-16 adaptor is required.

In addition, each station may require other connector wiring, depending on what options and accessories are installed.

Note: For more information on the DIG-2 digital interface and the DIF-102 frame which houses it, refer to the DIF-102/DIG-2 manual in the Eclipse set of manuals.

Single-Pair Digital

Single-pair digital wiring requires double-shielded 24 AWG conductor CAT-6E enhanced STP cable with RJ-45 connectors. Pair 1 transmits and receives multiplexed audio or data between the matrix port and the station.

Note: Ensure that the Select switch on the station’s rear panel is in the correct position for the intended use.

Figure 5: Matrix Frame to Digital Station Wiring Using RJ-45

Coax Digital

Coax digital wiring requires double-shielded 24 AWG conductor CAT-6 Enhanced STP cable connected to a 75-ohm (RG59) braid- shielded coax cable with a BNC-16 adaptor.

Pair 1 transmits and receives multiplexed digital and analog between the matrix port and the station.

External Program Feed Input

The external program feed input allows the station operator to simultaneously monitor audio from an external source and intercom audio.

The input is designed to accept a balanced, line-level audio feed at a nominal level of 0 dB. The program feed input passes through the station’s “Program” volume control before being mixed with the audio at the station. The program

feed (program audio) can be heard on the station’s speaker and headset; it cannot be heard by other stations in the Matrix system.

To connect an external program feed to the station:

1. Connect the balanced audio pair to pins 1 and 9.2. Connect a shield or ground connection if available to the connector’s pin 2

(see Figure 7 on page 1-4).

Logic Input #1 and #2

Each input can control one of several functions, determined through the configuration program. Typically, these inputs are connected to an external foot switch, a panel-mounted switch, or the logic output of another device.

The following functions are available:

• Mic On/Off—toggles the station’s microphone on and off.

• Mute Mic Output To Frame—turns off the audio from the station to the frame. It does not turn off the Hot Mic output (described in “OPT-100 Auxiliary Audio I/O Option” on page 2-7). For an example of how to use this option, see “External Program Feed Input” on page 2-4.

• Mic Off —momentarily turns off the station’s microphone.

• Answer Back Talk/Clear—the same functions as the station’s “Answer Back” key. Holding down the switch activates a talk to a label in the answer-back stack. To clear the label, quickly press and release the switch.

• Studio Announce—sends the output of the station’s selected microphone (panel or headset) to the station’s Studio Announce (SA) audio output, and activates the SA relay. The microphone output is not sent to the frame. The SA output and relay are only present if the station has the OPT-100 Auxiliary Audio I/O Option installed. (The SA options are described in “OPT-100 Auxiliary Audio I/O Option” on page 2-7).

• Speaker OFF—turns off the station speaker, disabling all audible output from the station.

• PTT: Activate All Talk Keys (Push To Talk)—when enabled from the configuration program and the logic input is active, the station behaves normally. When this function (logic level) is deactivated, it disables activation of all talk labels, implementing a push-to-talk function for the station. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active labels behave normally regardless of this input’s activity. This input controls momentary and latched talks.

• Activate Talk Switch #1—equivalent to pressing the station’s first (leftmost) talk selector; a momentary and latching activation.

• Activate Talk Switch #2—equivalent to pressing the station’s second talk selector; a momentary and latching activation.

• Activate Listen Labels Button—equivalent to pressing the “Listens” button on the keypad; all modes of the “Listens” button are supported.


• PTT: Activate Two-Way Radio Keys—implements a push-to-talk function for all two-way radio talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active two-way radio talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active two-way radio talk selectors operate normally regardless of the PTT status. This input only controls latched talks.

Use normally open type switches to activate the logic inputs. Connect the switches as follows (Figure 7 on page 1-4):• Logic input #1—pins 4 to 5 (pin 4 = ground)

• Logic input #2—Pins 11 to 12 (pin 11 = ground)

Note: Do not apply external voltage to the logic inputs.

Mute Relay Contacts

The mute relay is activated whenever any talk selector is activated at the station. The mute relay is commonly wired such that whenever it is activated, the volume of the monitor speaker in that room is decreased (muted). See Figure 7 on page 1-4.

Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 VDC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay.

Programmable Relay Contacts

Each station includes a relay controlled by the system program and independent of the local station function. This relay can be assigned to any label(s) in the system, which will activate whenever a talk or listen is set to that label(s). If activating the relay is the only action desired, assign the relay to a Control label. See the Eclipse Configuration System Manual for more details.

The relay can activate an external device, such as an applause light in a studio, a cue light, or a security door lock. Any programmable relay in the system can be activated from any station in the system, including a direct-inward-access caller. Figure 7 on page 1-4 shows the wiring of the relay contacts to the Miscellaneous connector.

Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 V DC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay.


OPT-100 AUXILIARY AUDIO I/O OPTIONThe OPT-100 Auxiliary Audio option provides the following features:

• Hot Mic output

• SA audio and relay outputs

• Auxiliary audio line level output

Figure 7 shows the pinout for the intercom station’s DB-15F Auxiliary Audio I/O connector. Following are descriptions and wiring information for the OPT-100 Auxiliary Audio I/O option.

Figure 8: Auxiliary I/O Connector

Hot Mic Output

The Hot Mic output is a balanced, line-level, transformer-isolated feed of the signal from the currently selected microphone (panel or headset). The Hot Mic output is active regardless of whether the station has talk paths set and regardless of the front-panel’s control settings.

Connect to pins 8 and 15 for a balanced output. Pin 7 is available as a shield or ground source (see Figure 7).

Studio/Stage Announce Audio and Relay Outputs

The SA output is a balanced, line-level, transformer-isolated feed with the same signal sent to the Hot Mic output, except it is only active when the SA button on the station’s front panel is pressed or when activated by Logic Input #1 or #2, which is configured for the Studio Announce Function.

Connect to pins 1 and 9 for a balanced SA audio output. Pin 2 is available as a shield or ground source (see Figure 7).

"Auxiliary I/O" Connector DB-15F


Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 VDC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay (see Figure 7). The following table shows the pins available for the SA relay.

Auxiliary Audio Line Level Output

The Auxiliary Audio Line Level output is a balanced, line-level, transformer-isolated feed of the input to the station’s internal speaker. For example, this output could be used to feed an external amplifier connected to loudspeakers.

Connect to pins 6 and 13 for a balanced output. Pin 14 is available as a shield or ground source (see Figure 7).

BINAURAL HEADSET WIRINGAlthough the station has a second earphone output, it functions and is wired differently than some other ICS stations. The output is not available on the “Miscellaneous” connector, but on the station’s main board on a separate header connector. This output would be available if a six-pin headset connector is installed on the front or rear of the station.

The default configuration of the station has both earphone outputs being fed with intercom and program audio. To separate the program input to the second ear only, use the configuration program.

Figure 8 shows the wiring of a six pin XLR connector for a binaural headset.

MAINS AC POWERThe station has a separate, external DC power supply with a removable AC power cord. The power supply is “universal,” operating over a voltage range of 90 to 260 VAC and 45 to 65 Hz. The maximum dissipation is 30 W.

A bracket has been provided to mount this external supply if necessary.

ADJUSTMENTSThe following station parameters are adjustable internally on the station’s main PCB by selecting options in the configuration program:

• Headset Sidetone

• Panel Microphone Gain

• Speaker Mute

• Page Volume Level

• Station-to-Matrix card Baud Rate

All these parameters are set to factory defaults. Most stations should operate at these default settings; however, some applications may require readjustment.

HEADSET SIDETONESidetone is the sound of the user’s voice in his headset.

Refer to the Eclipse Configuration System Instruction Manual for instructions on adjusting sidetone.

PANEL MICROPHONE GAINThe preamplifier gain of the panel microphone can be adjusted over a range of 0 to 10 dB; the maximum is the panel microphone gain’s default setting. However, if two stations are talking to each other at the same time with the panel microphone gain set to maximum, feedback may occur even if the speaker mute (see “Speaker Mute”) is set to maximum. In this case, it will be necessary to turn the panel microphone gain down. Similarly, in some noisy environments it may be necessary to turn the panel microphone gain down and have the operator talk more closely into the microphone.

Refer to the Eclipse Configuration System Instruction Manual for instructions on adjusting panel microphone gain.

SPEAKER MUTEWhen a panel microphone and a speaker are used together, feedback is possible. To reduce this possibility, the station software will mute (turn down) the speaker level by some predetermined amount when both the microphone and speaker are enabled. The speaker mute can be adjusted from 0 to 15 dB; its default setting is 6 dB.

Refer to the Eclipse Configuration System Instruction Manual for instructions on muting the speaker.

PAGE VOLUME LEVELWhen Page Override is assigned to a label, the audio level at the destination station(s) is predetermined. This function allows talking to someone even if his station’s volume control is off. Two things will happen when a station activates such a label:

• If the destination speaker was off, it will turn on.

• The station(s)’s speaker output will be at the predetermined level regardless of the “Intercom” volume control setting, unless this control is set higher than the predetermined level.

The page volume level can be adjusted within a range of 0 to 10, equivalent to the front-panel control settings of 0 equals off and 10 equals full pot. The page volume level’s default setting is 5.

Refer to the Eclipse Configuration System Instruction Manual for instructions on using Page Override.

STATION-TO-MATRIX CARD BAUD RATEThe RS-422 serial data communication between a station and other devices can operate at standard (19.2 k baud, the default) and long-line (9600 baud) baud rates. Use long-line only if encountering problems with the standard baud rate.

The baud rate is set from the configuration program and the station automatically adapts.


CONFIGURATIONAssign each station’s name and other parameters by using the Eclipse Configuration System Program (see Eclipse Configuration System Manual for more information). Also refer to the Operation chapter for details regarding the configuration options available from the ICS-2003’s menus.

ACCESSORY PANELSThe following sections describes how to install the following optional, accessory key panels:• The XPL-12 Display Expansion Panel adds 10 talk/listen selectors to a station.

• The XPL-22 Display Expansion Panel adds 20 talk/listen selectors to a station.

The installation procedure is identical for these two panels.

XPL TYPE EXPANSION PANELSThe XPL series provides selectors labeled with electronic displays that are automatically updated whenever changes are made.

Only one rack unit (1RU) of a standard Electronics Industry Association equipment rack is required for each expansion panel. The panels’ compact size makes them ideal for use in TV control rooms, edit suites, mobile OB vans, and any other location where many talk/listen keys are necessary but space it at a premium.

Model XPL-12 provides 10 additional selectors with displays and model XPL-22 provides 20 additional selectors with displays. Each station can accept a maximum of 60 additional selectors.

MOUNTINGAll accessory panels are mounted in a standard 19-inch wide (48.3 cm) standard Electronics Industry Association rack, requiring one unit of rack space each. Leave at least 2 in. (51 mm) of clearance behind the rear of the chassis to allow for cable connectors.

POWEREach XPL panel is powered by an external AC transformer (included). Confirm that the transformer is correct for the line voltage being used. To connect the AC power transformer to an XPL panel, route the transformer’s secondary lead to the “AC Power Input” connector on the back of the panel. This is a 2.1 mm coax connector. When routing the lead, use the lead stress relief on the back of the panel. The panel can be powered by any 12- to 16-V RMS AC source rated for 750 mA.


STATION CONNECTIONA cable is supplied with each panel to connect it to a station or to additional panels. The cable is 6-ft. long (1.8 m) and has a DB-9F connector on one end and a DB-9M connector on the other end. If custom length cables are to be made, they should be made with 9 conductor control cable with 22 to 24 AWG wire. The pins should be wired one-to-one between the male and female connectors. The maximum distance between the station and the last expansion panel should be 25 ft. (7.6 m).

To connect an accessory panel to an intercom station:

1. Plug the DB-9M end of the cable supplied into the “Accessory Panel” connector on the back of the station.

2. Plug the DB-9F end into the “From Intercom Station” connector on the rear panel of the accessory panel.

To connect an additional accessory panel:

1. Plug the DB-9M end of the additional key panel’s cable into the “To Next Expansion Panel” connector on the back of the preceding key panel.

2. Plug the DB-9F end of that cable into the “From Intercom Station” connector on the back of the additional key panel.

More panels can be added by using this “daisy-chaining” method.

The numbering of expansion selectors will be in the order of the daisy chaining. The first panel will be selectors 1 to 20, the second will be selectors 21 to 40, and so forth.

CONFIGURATIONAfter physically placing the key panels and connecting them to a station, the number of accessory keys installed in the station must be programmed into the configuration program. Refer to the Eclipse Configuration System Instruction Manual for more information.


MAINTENANCE

INTRODUCTIONThis chapter provides station microprocessor resetting instructions, maintenance menu use, troubleshooting guidelines, schematics, assembly drawings, and component lists.

STATION RESETThe station’s microprocessor has a reset button located in an unmarked hole just below the program volume knob on the right side of the unit’s front panel. If the station is acting erratically, try resetting it by performing one of the following:

WARRANTY REPAIRSWhile VGC will ensure complete system integrity by providing whatever support is necessary to resolve any failure covered under the terms of the warranty, the normal procedure will be to repair or replace any defective Line Replaceable Unit (LRU) that is returned to VGC during the warranty period.

A Line Replaceable Unit (LRU) is defined as: an assembly that can be safely removed from the system and readily replaced by plugging in a new unit. In the case of ancillary items such as power supplies, the entire power supply would be returned. Whereas, in the case of circuit cards, control panels, etc., only these assemblies would be returned for repair. All equipment provided by VGC is covered under the warranty.

This warranty does not include defects arising from installation (when not performed by VGC), lightning, power outages and fluctuations, air conditioning failure, improper integration with non-approved components, defects or failures of customer furnished components resulting in damage to VGC provided product.

NON-WARRANTY REPAIRSEquipment that is not under warranty must be sent prepaid to VGC. If requested, an estimate of repair costs will be issued prior to service. Once repair is approved and completed, the equipment will be shipped freight collect from the TSC.

REPLACEMENT UNITSShould VGC determine, in its reasonable discretion, that any part of a product is defective due to faulty materials or workmanship, VGC shall at its expense, repair or replace such part and return the repaired/replacement part to the customer. The provisions of this warranty shall apply to the repaired/replacement part for the unexpired portion, if any, of the warranty period.

EMERGENCY ON-SITE ASSISTANCEVGC can provide emergency on-site technical assistance in support of warranty activities. The level of support effort required will be decided on a case-by-case basis. VGC has the qualified technical staff to support any and all emergency site activities should they occur.

LIABILITYThe foregoing warranty is VGC’s sole and exclusive warranty. There are no other warranties (including without limitation warranties for consumables and other supplies), or guarantees, expressed or implied (including, without limitation, any warranties of merchantability or fitness for a particular purpose), of any nature whatsoever, whether arising in contract, tort, negligence of any degree, strict liability or otherwise, with respect to the products or any part thereof delivered


hereunder and/or with respect to any non-conformance or defect in any such product and/or part thereof delivered hereunder and/or with respect to any non-conformance or defect in any such product and/or part thereof delivered hereunder, or any other warranties or guarantees, including but not limited to any liability of VGC for any consequential and/or incidental damages and/or losses (including loss of use, revenue, and/or profits). In any event, the maximum extent of VGC’s liability to customer hereunder shall not under any circumstances exceed the cost of repairing or replacing any part(s) fount to be defective within the warranty period as aforesaid.
