Set-up and Configuration Functions

This section explains how to access and set the Set-up and Configuration functions that are provided for the 2.048Mbps Wireless Modem. The main parameters to set are:

•Line interface unit set-up parameters

•Management control parameters

•Modem set-up parameters

•Radio set-up parameters

Accessing the Set-up and Configuration Functions

You can access the Set-up and Configuration functions by connecting a terminal to the RS232/V.24 monitor interfaces on the rear panel of the 2.048Mbps Wireless Modem.

The local monitor allows you to access the set-up parameters from an ASCII ANSI terminal, or from a PC running a terminal emulation program, such as the Windows Hyper Terminal or Procomm. Use the following settings:

•Baud rate 9600

•Data bits 8

•Stop bits 1

•Parity None

•Flow control None

•Connector Available Com port

Connect the terminal to the monitor interface of the 2.048Mbps Wireless Modem. The monitor appears displaying the main menu.
