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.
