4.8Modem Connections

A COM2 port is provided on the COM2 Port Adapter or the Redundant TP Ethernet + COM2 Port Adapter. The COM2 port can support serial connections for the following dial-up interfaces:

External modem

Point-to-point protocol (PPP) services

Wide area network

The COM2 port provides a single DB-9 connector wired for an RS-232 DCE signal. The COM2 Port Adapter plugs into any NET slot (slots 11 and 12) of the D400. The Redundant TP Ethernet + COM2 Port Adapter plugs into the NET1 slot (slot 11).

Note: The COM2 Port requires an external modem to provide dial-up functionality. See section “3.11 COM2 Port Adapter” for more information.

»To connect a modem to the COM2 Port Adapter, use a straight-through modem cable (not supplied with the D400):
