4. Circuit protection devicesThe CPZ-2464 is equipped with circuit protection devices; the device can protect the transistors.Total current of eight transistors flows into the circuit protection device (fuse current rating: 1 A). Itcannot protect only one transistor.

5. Reset signal output/power supply status output (RSTOUT/P.OUT)This board’s reset signal or power supply status is output from pin 21 on the connector CN1depending on the setting of the JP3 jumper block. This allows you to monitor the status of the board.

6. External reset input (RSTIN)The RSTIN signal resets this board. This signal can also be configured as one of the interrupt sources.

7. Built-in timer/counterThe CPZ-2464 has a timer/counter circuit that can be used as an interval timer. A software selectableclock period of 10 µs, 100 µs, 1 ms, 10 ms, and 100 ms and a software programmable frequencydivisor in the range of 1 through 15 are supported. The output of the built-in timer/counter circuit canbe used as an interrupt source.

2.3 Data Transfer with Handshake Using Control Signals

By using the control signals (ACK1, ACK2, STB1, and STB2), data transfer with handshake can beachieved. The following figure illustrates an example of data transfer with handshake.

ACK2

Input data

Computer A

DI board

STB1ACK1

DO boardOutput data

STB2STBACK

Data

Computer B

First, Computer B puts the data on the DO board. Then it asserts the STB2 signal to notify the completionof the process to Computer A. When the DI board on Computer A detects that the STB signal is asserted,it latches the input data and notifies Computer A that the data have arrived using the STB1 register or aninterrupt. Computer A reads the latched data, and then asserts the ACK1 signal to notify Computer B thatinput data has been read. After the DO board recognizes that the ACK signal is asserted, it notifiesComputer B that Computer A is ready to receive new data. Then Computer B may start to transfer newdata.

CPZ-2464


2.4 Control Signals for Data Output (STB2, ACK2)

1. STB2: Output-Data Strobe (out)The STB2 signal notifies an external circuit that this board has written data on its output pins. Toassert or deassert STB2, write specific data to the command register of this board. To confirm thestatus of STB2, read the status register of this board.

2. ACK2: Output-Data Acknowledgement Signal (in)The ACK2 signal can be used as a signal to notify this board that an external circuit has read the data.The ACKR2 register changes from 1 to 0 after ACK2 is asserted. At this point, STB2 is deasserted.ACKR2 still maintains the 0 state when ACK2 is deasserted. When STB2 is asserted, ACKR2changes from 0 to 1. ACK2 can also be used as one of the interrupt sources.

When the power is turned on or the system is reset, ACKR2 is 1 and STB2 are deasserted.

interrupt mask. (Only the corresponding interrupt source)• When the CompactPCI bus reset occurs.• When the RSTIN signal is asserted.

SIGT• When the software deasserts the request explicitly.• When you change the interrupt mask. (Only the corresponding interrupt source)• When the CompactPCI bus reset occurs.• When the RSTIN signal is asserted.• When the interval timer is reset.

SIGR• When the software deasserts the request explicitly.• When you change the interrupt mask. (Only the corresponding interrupt source)• When the CompactPCI bus reset occurs.

When the computer is turned on, all interrupt requests are cleared.

CPZ-2464


2.5.1 Interval Timer

The interval timer can be used to generate an interrupt to the host computer every timer cycle. The timercycle period is given by the following equation:

T = RATE × CLK.T: Timer cycle periodRATE: 1 through 15CLK: 10 µs, 100 µs, 1 ms, 10 ms, 100 ms

This timer begins counting immediately after both RATE and CLK are programmed, and it will keepcounting until a stop instruction is issued. It is recommended that you use an interrupt timer intervalgreater than or equal to 10 ms. Windows cannot handle a large number of interrupts within a short timeperiod. In such a case, Windows may hang up or freeze.

4.4 Example Connections

Keep these important points in mind when connecting the board with external equipment.

4.4.1 General Purpose Digital Outputs (OUT1 through OUT64)

The digital output circuit has 64 outputs, numbered from OUT1 through OUT64. Programs can write datato output pins by issuing the OUT instructions to the corresponding I/O port addresses. The maximumoutput current per channel is +100 mA. The clamping diodes in the Darlington transistor (TD62597AFN)can be used to suppress inductively induced voltage. However, we recommend using external rectifyingdiodes near inductive loads.

4.5 Protecting Output Transistors

4.5.1 Suppressing Inductively Induced Voltage

When the dc voltage is switched off in an inductive circuit, a high voltage is induced to attempt tomaintain the current in the circuit. As a result, an arc is produced at the contact of the switch. When youuse this board to control an inductive circuit, the high voltage spike generated by switching off aninductive device may damage the output transistor on the board. You should protect the circuit by using aclamping or despiking diode.

Rectifying DiodeThe diode connects in reverse bias against the power supply positive voltage to prevent short circuit.When the transistor switches off the circuit, the induced voltage forward-biases the diode then the currentflows through the diode. The coil is safely discharged. The reverse direction breakdown voltage of thediode requires ten times the applied voltage.

Zener DiodeThe Zener diode connects with the coil in series and with the output transistor in parallel. When thetransistor switches off the circuit, the reverse-biased Zener diode flows the current to discharge the coil.The Zener voltage of the Zener diode is recommended to be nearly equal to the power supply voltage.

4.5.2 Suppressing In-rush Current

When a lamp is turned on, excessive current called as in-rush current could flow in the circuit. Theovercurrent may damage the output transistor of this board. The in-rush current could reach 10 timesnormal operating current. If the peak value of the current exceeds the maximum current rating of theoutput transistor, you should protect the output transistor.

Shunt ResistorA shunt resistor connects in parallel to an output transistor to sink, or bypass, current. The resistance of theshunt resistor may require from 20% to 30% of the lamp resistance to reduce the peak of the in-rushcurrent to half. In this shunt resistor configuration, the circuit dissipates power regardless of the outputtransistor switching state.

4.5.3 Reset Output/Power Supply Status (RSTOUT/P.OUT)

The signal that appears on pin 21 of CN1 is selectable by the setting of the JP3. The following signals canbe selected:

• Reset signal that consists of what the CompactPCI bus reset signal, the on-board power on resetsignal, and external reset signal are ORed.

• Power supply status

To select the reset signal, set the jumper on position A of JP3. To select the power supply status, set thejumper on position B of JP3. Each output circuit can sink up to +100 mA of current for RSTOUT/P.OUT.

4.5.4 Reset Input (RSTIN)

A signal on pin 69 of CN1 is an external reset signal. When this signal is asserted, an interrupt occurs toyour computer. This signal can be masked or unmasked. To be recognized as a valid reset signal, a 10 µsminimum assertion of the RSTIN signal is required.
