1.OutlineZS-6122CP is a GP-IB adapter that can control the input and output of parallel signals up to 4bytes with the GP-IB interface. Parallel signal can be set to input or output with each byte by
DIP switch.
Using this unit makes it easy to control and transfer data of input / output interface devices
such as BCD parallel signals and binary signals by GP-IB.
There are 2 types of model as below.
(1) ZS-6122CSIt is a unit that incorporates ZS-6122CP and power supply in a small case.

(2) ZS-6122CP Printed circuit board type.
It is easy to incorporate it into a machine with height limitation since the L
shape is used for the connector that connects the I/O data and the control
signal. Refer to the user’s manual of ZS-6122CP for signal connection,appearance etc.

2.Fearture1.

It has both input and output functions.

2.

It is a small size and low price.

3.

It is easy to incorporate with equipment.

3.Specifications(1) Compliant with GP-IB interface standard (IEEE Std 488-1978).
Subset of interface function： SH1,AH1,T6,L4,SR1,RL1,PP0,DC1,DT1,C0(2) The adapter sends the input data to the control side of the GP - IB interface in talker
operation.
Number of input data: 0 to 4 bytes (Delimiter by DIP switch is fixed to EOI).
Signal level: TTL (Fan-in = 1, 10 kΩ pull-up resistor).
(3) The adapter outputs data from the control side of the GP - IB interface in listener operation.
Number of output data: 0 to 4 bytes (Delimiter by DIP switch is optional).
Signal level: TTL (74 LS equivalent, fan- out = 10).

A negative pulse is output when outputting arbitrary dummy data after
all the bytes of output data are aligned. About 1µs or 1ms can be selected
for this pulse width according to the setting of DIP switch.
