Preconfigure Optional Modem

Preconfigure Optional Modem

1.If a modem is to be connected to the Access Navigator for remote operation, the modem must be pre-configured before installation and connection to the Access Navigator’s RS-232 CLI management port. Preconfigure the modem as follows:

2.Connect modem to a computer, using an appropriate RS-232 cable.

3.Apply power to the modem.

4.On the computer, start up a terminal emulation program such as HyperTerminal and send the following initialization string to the modem:

at s0=1 e0 q1 &c0 &d0 &w

NOTE: The above initialization string uses Hayes compatible modem commands for attention (at), auto-answer (s0=1), no local echo (e0), no result codes (q1), no hardware handshake (&c0 &d0), and write configuration into non-volatile RAM (&w). If the modem is not Hayes compatible, substitute equivalent commands.

5.Disconnect modem from computer.

6.Connect RS-232 cable from modem to Access Navigator RS-232 CLI management port.
