This appendix lists pin assignments for port interfaces on CS/2500 and
CS/2600 series communications servers.
The CS/2500 and CS/2600 include three types of port interfaces:
■Ten serial RS-232-D or RS-422 connectors
■One 802.3 Ethernet (transceiver) connector
■One parallel printer connector
RS-232 Serial Ports The CS/2500 and CS/2600 have ten serial ports, labeled J0C through J9C, that provide RS-232 support and limited RS-422 support for connecting host and terminal devices to the server. Figure A-1 shows pin numbering for these ports.
Figure A-1 Serial Connector Pin Numbering
Table A-1 lists RS-232 pin assignments for devices attached to the serial ports. The communications server acts as a DCE device and can be attached to a DTE device, such as a terminal, host, or printer, using a straight-through cable. If you want to connect the server to a DCE device, such as a modem, use a null modem cable.
