COM Port Interface

The COM port connects to a PC for front panel emulation, to an ASCII terminal or printer for alarms, to an async terminal, to a network device (e.g., a router) for SNMP or Telnet applications, to the LAN Adapter for SNMP or Telnet applications, or (for Model 3164) to another DSU/CSU’s AUX port for daisy chain connectivity.

(The SNMP LAN Adapter includes the cable that is needed to attach it to the DSU/CSU.) The COM port connector is an 8-position unkeyed modular connector (Table E-5, COM Port Connector). The data signals on this port are referenced to a DTE interface.

The COM port-to-PC cable is shown in Figure E-5, COM Port-to-PC Cable, and the COM port-to-terminal/printer cable is shown in Figure E-6, COM Port-to-Terminal/Printer Cable.

NOTE:

For daisy-chaining an AUX port to a COM port (Model 3164 only), a

25-pin-to-8-pin cable is required and the appropriate configuration options (Com Use and Aux Use) must be set to Daisy. Whenever the cable is connected or disconnected, you should change the Daisy selection to ensure that the correct parameters have been negotiated for the link layer.
