Note: ports 3, 4, 7, 8, 11, 12, and 15 do not support the RI signal.
Technical Tip:
Please ensure that you terminate the DCD or CTS signals if your
application does not use them. The common way to do this is to
connect DCD to DTR and/or to connect CTS to RTS. Failure to
do so may result in a loss of a performance on your Intellicon-
NT960/PCI subsystem.
ACM/Flex16 SLIM Pinouts
You may order the ACM/Flex16 external module with RS-232,
RS-485/422 and/or 20mA Current Loop Serial Line Interface
Modules (SLIM). Please refer to Table 5 for the pinouts for the
SLIM sockets found on the ACM/Flex16 module.
