Overview The PK-232SC is the latest generation of multimode data controllers built upon the solid foundation of the legendary PK-232. The PK-232SC features an expanded interface to connect and control your radio transceiver, station accessories and computer. The key to the new PK-232SC is a single USB cable from your PK-232SC to your computer. No other connection is necessary. Note the PK-232SC block diagram in Figure 1. The USB cable from the computer connects to a four port USB hub inside the PK-232. Port 1 of the USB hub connects to a dual USB-to-UART bridge. One of the UART serial ports connects directly to the PK-232SC UART serial port. This shows up on your computer as a standard COM port. Your software terminal program connects to this COM port to control the PK-232SC. The other UART serial port is the rig control port. This optically isolated port supports Icom CI-V, Yaesu CAT, Kenwood logic level, and RS-232 connections. This shows up on your computer as an enhanced COM port. Your software rig control program controls your transceiver. Port 2 of the USB hub connects to a USB Audio sound card inside the PK-232SC. The sound card audio is transformer isolated from the USB circuitry. The sound card/PK-232 switch or a software command selects either sound card transmit audio or PK-232SC transmit audio. Receive audio from your transceiver is always connected to both the sound card receive audio and the PK-232 receive audio. Ports 3 and 4 of the USB hub connect to a dual USB jack on the back panel of the PK-232SC. Use these jacks for rig control of USB-equipped transceivers and for other USB station accessories. A new feature in the PK-232SC is an instant reset switch. A quick flick of the switch when the power is off resets the PK-232SC to factory default condition.

Operation Note: This manual covers the features added with the SC version of the PK-232.

The main PK-232 manual describes the modes and features found in the original PK-232 and PK-232MBX. The DSP manual supplement describes the DSP board features.

PC USB Connection Connect the PK-232SC to an USB 2.0 compatible port on a computer with a single USB cable (USB miniB to USB A). No other computer connections are required. The computer USB port must be capable of supplying full USB power (5.0 Volts @ 500mA.) If a USB hub is used, it must be a powered hub.

USB device driver The device drivers for Windows XP/VISTA/7 will load automatically when the PK-232SC is connected to your Windows PC if it is connected to the internet. The drivers are also found on the CD distributed with the PK-232SC and on the Timewave web site (www.timewave.com.) Other drivers are available for Linux and Apple computers. Please contact Timewave or visit the Timewave website for further information. Note: This device driver is different from previous PK-232/USB device drivers. The older drivers will not work for the PK-232SC.

Power Connect the PK-232SC to a +13VDC @ 750 mA. power supply. Press the PK-232SC power switch to the IN position. This connection is the same for all models of the PK-232.

Radio Connect your radio data audio input, data audio output and PTT line to the PK-232SC Radio 1 or Radio 2 ports. This connection is the same for all models of the PK-232. If you are upgrading your PK-232MBX to a PK-232SC, you can use your existing cable if you do not change radios. This connection is the same for all models of the PK-232.

PK-232SC Ports The PK-232Sc has two COM ports, a USB Audio sound card port and 2 USB ports.

The PK-232 terminal program uses the “standard” COM port to control the PK-232SC operation.

The PK-232SC rig control program uses the “enhanced” COM port to control your transceiver.

The PK-232SC sound card mode programs use the “USB Audio Codec” to run sound card programs.

The PK-232SC USB ports appear on your computer USB port list and can be used for USB 2.0

compatible USB devices.

13

Some programs will automatically identify the correct ports for their functions. Others may have limited ability to aid you in connecting the correct port to your software application. If you wish to identify or edit the various PK-232SC ports, use the Device Manager application found in Windows XP/VISTA/Win7. Go to Control Panel/System or Computer/properties to find Device Manager. You should learn to use Device Manager to help you understand and manage the hardware configuration of your PC for all your devices and programs.

PK-232SC Control The PK-232 terminal program uses the “standard” COM port to control the PK-232SC operation. You can use a variety of programs to control the PK-232SC A “dumb” terminal program such as Hyperterminal (Windows XP) or puTTY allows you to control the PK-232SC in command mode. There is little or no automation so all commands must be entered manually. Some programs have macros that let you create commands by stringing together a series of commands that can be sent with one or two keystrokes. Other programs offer complete control of the PK-232SC with standard Windows graphical commands, mouse actions and keystrokes. If you need a program with complete PK-232SC support, Timewave recommends Radio Operating Center (ROC) from W4PC Software, Inc. (www.w4pcsoftware.com). We suggest you contact the author of your favorite program to determine its level of PK-232SC support. Timewave has a free applet called “ModemSwitch” (www.timewave.com.download.html that will switch the PK-232 from transmit to receive and from sound card to PK-232 mode. It also has a simple dumb terminal program for testing the PK-232.

Rig Control Connect your radio rig control port to the matching PK-232SC CAT/CIV, 8 pin miniDIN, or RS-232 connector. Only one of the three connectors may be connected at one time. You may also connect one of the two USB connectors to your radio if it supports USB rig control. Rig control is a connection for the PK-232SC only. Earlier models of the PK-232 do not have this connection. Timewave has several standard rig control cables for popular models of radios. We can supply a cable for any compatible radio. Please contact us for details. Your rig control software and your radio determine your rig control operating features. The PK-232SC rig control circuitry is an interface only and does not affect the actual rig control operation. Timewave recommends Radio Operating Center (ROC) from W4PC Software, Inc. (www.w4pcsoftware.com) and Ham Radio Deluxe (www.ham-radio-deluxe.com) for rig control. The PK-232SC operating COM port and the PK-232SC rig control COM port are independent. You can use different PK-232SC operating and rig control programs simultaneously. For example, you may use Ham Radio Deluxe for rig control and ROC for operating a PK-232SC mode such as Pactor.

USB Audio Sound Card The USB audio sound card built into the PK-232SC appears as a separate audio device on your PC. It is called “USB Audio Codec”. No software driver is necessary when you use the USB Audio Codec. You must select the USB Audio Codec when you configure your terminal program to operate sound card modes such as PSK-31. Use the program settings window in Radio Operating Center or the soundcard settings in Digital Master 780 found in Ham Radio Deluxe.

14

SC Board Jumper Settings The SC board has several jumper options that may be changed by the user. In most instances the jumpers can be left at the factory default settings. The jumpers are located on the SC daughter board at the rear of the PK-SC. Rig Control Not all transceivers have the same polarity settings for their logic level rig control ports. The PK-232SC polarity settings for RX, TX, RTS and CTS can be changed to meet the requirements of any specific transceiver. The factory default settings for JP1 (RX), JP2 (TX), JP3(RTS) and JP4(CTS) are pins 1& 2 connected. Connecting pins 2 & 3 will invert the polarity for one line only. Change these settings only if you cannot your rig control program to recognize your transceiver. Most transceivers will not require any change! USB Jack Power The two type B USB jacks on the PK-232SC default power output is 5 Volts @ 100 mA. This power is derived from the computer or powered USB hub upstream from the PK-232SC. If the jumper on JP5 is connected between pins 2 &3 (factory default), the external power supply will not be connected. The USB circuitry will draw its power from the upstream USB device. If you want to draw more than 100 mA. (500mA. max) from the PK-232 USB hub ports, you may connect a 5.0 VDC @ 2A power supply to the PK-232. To do so you must enable the 5.0VDC power jack in the middle of the PK-232SC back panel. Change the jumper on JP5 to pins 1 & 2. With the jumper in this position, you must use the 5.0 VDC power supply so the USB circuitry will work! USB Audio Sound Card Channel Combinations The USB Audio sound card has two channels. Receive Audio Input In the factory default mode, the PK-232 sound card input (receive audio) is fed to both channels simultaneously. Connecting JP23 pins 1 & 2 enables the factory default combined channel mode. In optional mode, the PK-232 sound card input (receive audio) is fed to the left sound card channel and the Aux Audio input (J10-ring on the SC connector board) is fed to the right sound card channel. Connecting JP23 pins 2 & 3 enables the optional split channel mode. Transmit Audio In the factory default mode, both USB Audio sound card output channels feed the PK-232 sound card output (transmit audio) simultaneously. Connecting JP3 pins 1 & 2 enables the factory default combined channel mode. In optional mode, the left sound card channel feeds PK-232 sound card output (transmit audio) and the right sound card channel feeds the Aux Audio output (J10-tip) on the SC connector board.) Connecting JP2 pins 2 & 3 enables the optional split channel mode.

Data Sheet

PK-232SC Multimode Data Controller Now with USB Audio, Rig Control and Single USB Computer Cable! Features Digital Signal Processor 18 DSP Filters Twin Peak RTTY Filters Adaptive PACTOR filters Works with all sound card modes USB Sound Card Audio RS-232, logic level & USB Rig Control for Icom, Yaesu & Kenwood radios Single USB Computer Connection Galvanic Computer Isolation SC Upgrades for all PK-232 models

Timewave’s customers swear by their DSP filters and PK-232 owners love the flexibility and reliability of the most popular data controller ever built. Now with the addition of a built-in sound card, rig control, computer isolation and total USB connectivity, the PK-232SC rolls it all into one! The PK-232SC brings a new level of performance to the legendary PK-232 with sharp, accurate DSP filters for all its internal data modes and dual transformer isolation for sound card data modes. Weak signals magically appear from the noise and QRM bounces off the new DSP filters for cleaner copy with fewer errors than the old analog filters.

More Filters, Better Filters, Automatic selection The PK-232SC brickwall filters have tighter bandwidth and steeper skirts for improved noise and QRM rejection. New PK-232 firmware (Ver. 7.2) allows a wider selection of filters than the original PK-232, so the filter can match the mode. The correct DSP filter is automatically selected when you choose an internal mode. In RTTY, Timewave’s proven Twin Peak Filters pluck the mark and space tones from the noise and QRM for great copy. In PACTOR, the filter bandwidth automatically changes when the baud rate shifts in response to the error rate of the link. In Morse (CW), the operator can preset either 100 Hz or 200 Hz bandwidth. The PK-232SC is compatible with all Windows XP, Vista, and Windows 7 software terminal programs for the PK-232.

Sound Card Interface and Rig Control For maximum flexibility, Sound Card / TNC switching is both software and panel switch controlled. The sound card mode selection is software controlled. For example, when operating with Radio Operating Center software, changing to PSK31 from Pactor or MT63 is a simple menu click. The single USB cable from your PC also moves your logic level Kenwood RX/TX/RTS/CTS, Yaesu CAT, and Icom CIV, RS-232 and USB Rig Control interface to the back panel of your PK-232SC.

16

All the Proven Modes + All the Sound Card Modes The PK-232SC supports all the new sound card modes in addition to all of the existing PK-232 modes - Pactor, VHF/HF Packet, AMTOR/SITOR, Baudot, ASCII, Morse, HF Weather FAX, TDM, and NAVTEX. The PK-232SC comes with a complete cable and connector set in addition to Timewave’s on-line and telephone support. As always, you can upgrade any PK-232 ever built to the latest PK-232SC!
