Changes required for CS/CJ-series product
Wiring
The connector has been
changed from a 25-pin to a
9-pin connector.
The CS/CJ-series products
do not support the ST1, ST2,
and RT signals and wiring
them is not required.
The connector has been
changed from a 25-pin to a
9-pin connector.
No changes have been made
in wiring.
No changes have been made
in wiring.
Port 1:
The connector has been
changed from a 25-pin to a
9-pin connector.
Port 2 set for RS-232C:
The SG signal has been
changed from pin 7 to pin 9.
Other
The following changes are necessary for
systems that sync with ST1, ST2, and RT.
Synchronized transfers will no longer be possi-
ble.
Full-duplex transmissions will be possible with
the CS/CJ-series product, but the host com-
puter's communications program, hardware, or
both will need to be altered.
The following changes are necessary for
systems that did not sync with ST1, ST2,
and RT.
It may be possible to use the host computer
programs without alteration as long as the
same communications settings (e.g., baud rate)
are used. It may be necessary, however, to
change programs to allow for different text
lengths in frames or different CS/CJ command
specifications. (See note.)

The following changes are necessary for
half-duplex transmissions that use CD.
Check the system for timing problems when
using SEND, RECV, or CMND to initiate com-
munications from the PLC or timing problems in
sending commands from the host computer. If
necessary, switch to full-duplex transmissions.
The following changes are necessary for
full-duplex transmissions that do not use
CD.
Half-duplex It may be possible to use the host
computer programs without alteration as long
as the same communications settings (e.g.,
baud rate) are used. It may be necessary, how-
ever, to change programs to allow for different
CS/CJ command specifications.
