Local access to the control console
You can use a local computer that connects to the
Main Module through the serial port on the rear of
the unit to access the contr ol console.
1. Select a serial port at the local computer, and
disable any service that uses that port.
2. Use the provided RS-232 configuration cable
to connect the selected port to the serial port
on the rear panel of the Main Module.
3. Run a terminal program (such as
HyperTerminal®) on your computer and
configure the selected port for 9600 bps, 8
data bits, no parity, 1 stop bit, and no flow
control, and save the changes.
4. Press ENTER to display the User Name
prompt.
5. Use apc for the user name and password.

Module, you can use ARP and Ping to assign an IP
address to a Main Modu le, and then use Telnet to
access that Main Module’s control console and
configure the needed TCP/IP settings.
Note: After the Main Module has its IP
address configured, you can use Telnet,
without first using ARP and Ping, to
access that Main Modul e.
1. Use the MAC address of the Main Mo dule in
the ARP command to define the IP address.
For example, to define an IP address of
156.205.14.141 for a Main Module that has a
