ZS-6 44AF is an interface conversion adapter that mediates communication between
GP-IB and RS-232C.
ZS-6 44AF operates as an interface converter for incorporating devices with
RS-232C interface into the GP-IB system, and devices with RS-232C interface can
communicate with the GP-IB controller.

4. Operation
4- Operation sequence
ZS-6 44AF operates as an interface converter that communicates between the
GP-IB controller and the RS-232C interface device.
The RS-232C side is in full duplex communication method and the transfer is
performed regardless of the GP-IB side status as a talker or a listener.

In case of buffer memory is ON.
（）Talker operation
The data received from the RS-232C is sequentially written the 6 Kbyte buffer
memory. When talker is specified, data in the buffer memory is output to the
GP-IB side.
When the RS-232C data received buffer memory becomes full, the received data
is discarded without being written to the buffer memory.
（2）Listener operation
When the listener is specified, the data received from the GP-IB is written to
the 8 Kbyte buffer memory. If the RS-232C side is receivable state, data in the
buffer memory is output to the RS-232C side. In this case, it is necessary both
CTS and RTS is ON.
GP-IB handshake is stopped when the data reception buffer memory becomes
full. When the amount of data becomes 2 Kbytes or less, the handshake restarts.
In case of buffer memory is OFF
It is used when transmission / reception data always needs latest data from the
other side.
When buffer memory is turned OFF, delimiters separate the continuous data.
If the data received before receiving the delimiter exceeds 6 Kbytes, it discards
the data received so far and stores the newly data.
For example, when receiving a delimiter after receiving 8 Kbytes of data, only
the last 2 Kbytes are sent from the sender to the receiver.
If the next new data(B) is sent before sending the received data(A) to the
partner side, the data(A) is discarded and it is rewritten to the data(B)
Note) Delimiter setting is done with the MODE switch. For the setting of the
MODE switch, refer to page 7.

SRQ is generated in the following cases when SRQ function is turned on with DIP
switch (SW3).
) When the amount of data in buffer memory is exceeded by the data from
RS-232C.
2) When the amount of data in buffer memory is exceeded by the data from GP-IB.
3) When RS-232C communication error occurs (parity error, framing error, overrun
error).

4-3 Flow control of RS-232C
In data transfer with RS-232C, it is possible to perform flow control using X
parameter or control line to prevent loss of received data.
（）Flow control by control line
This mode is effective when the other device can perform flow control by the
control line.
When data reception is possible, the RTS signal is turned ON, and RTS signal is
turned OFF when the amount of data in buffer memory is exceeded.
RTS is turned OFF, data is output to the GP-IB side. RTS is turned ON again
when the amount of data buffer memory is less than 4 K bytes.
（2）Flow control by X parameter
This mode is effective when the other device can perform flow control by X
parameter.
① It transmits an X-OFF code( 3H) and requests the other device to pause
transmission when the amount of data buffer memory is exceeded by the data
from the RS-232C interface device.
ZS-6 44AF transmits an X-ON( H) code and requests transmission from the
other device when the amount of data in buffer memory becomes 4 Kbytes or
less after transmitting the X-OFF code.
② Receiving an X-Off code from the RS-232C stops transmission and restarts
transmission when receiving an X-ON code.
4-4 Error message
When an error occurs, operation is stopped and error contents are notified by
blinking the LED on the front panel.
Note) Error will be cleared when power is turned on again.

GP-IB address, RS-232C communication protocol, and operation mode are set with
the switch on the board. Take the screws at the 4 corners and remove the top cover
to make the setting. The LED indicates the communication status of GP-IB and
RS-232C.
Note) There is a product with SW (4 bit dip switch) mounted on the left side of SW2, but please
use this switch in its initial state.
