Modem configuration
This page allows you to 
configure the COM1 serial 
port located at the rear of 
the CPU IP.

Server IP / Client IP
When a user dials into the CPU IP via a modem or ISDN adapter, the CPU IP 
sets up a temporary two-device network using PPP (Point to Point Protocol). For 
this purpose, both devices must have ‘dummy’ IP addresses so that they can 
communicate correctly. These two addresses can be almost anything expressed 
in the quad octet format (i.e. 192.168.3.1.). However, it is advisable not to make 
them the same as the real IP addresses used by either the remote system or the 
CPU IP. 
Baud rate
This option configures the speed of the serial connection between the CPU 
IP and a connected modem or ISDN terminal adapter. The default setting is 
115200. The other communication settings are fixed as: No parity, 8 bit word, 1 
stop bit.
Init string
The codes entered here are used to prepare the connected modem or ISDN 
terminal adapter for use with the CPU IP. The default code is a Hayes-compatible 
string to configure auto answer mode and would be understood by the vast 
majority of modem/ISDN devices. The code is sent when the CPU IP is first 
switched on or whenever the Initialize button is clicked.
Initialize port
When selected, this option sends the characters entered in the ‘Init string’ field 
to the connected modem or ISDN terminal adapter.
Restore Defaults
When selected, this option resets the ‘Baud rate’ and ‘Init string’ values to their 
original default settings.
To get here
1  Use the local keyboard and log on as the ‘admin’ user.
2  Press 
 
   (hotkeys may be different).
3  Select ‘Configuration’.
