The connector has been
changed from a 25-pin to a

The SG signal has been
changed from pin 7 to pin 9.
The following changes are necessary for
half-duplex transmissions that use CD.
Check the system for timing problems when
using SEND(90), RECV(98), or CMND(––) to
initiate communications from the PC 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.

Note The number of words that can be read and written per frame (i.e., the text
lengths) when using C-mode Host Link commands is different for C-series Host
Link Units and CQM1H-series Serial Communications Boards. A host computer
program previously used for C-series Host Link Units may not function correctly
if used for CQM1H-series PCs. Check the host computer program before using it
and make any corrections required to handle different frame text lengths.
