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.
