Serial port configuration

This page provides all access to settings concerned with the two serial ports (modem and power control) that are situated at the rear of the ServSwitch CX with IP unit.

To get here

1Using VNC viewer or a browser, log on as the ‘admin’ user.

2Click the ‘Configure’ button in the top right corner.

3Click the ‘Serial port configuration’ option.

Modem port

PPP Server IP Address / PPP Client IP Address

When a user dials into the ServSwitch CX with IP via a modem or ISDN adapter, the ServSwitch CX with 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 ServSwitch CX with IP.

Baud Rate

This option configures the speed of the serial connection between the ServSwitch CX with 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.

Initialization Sequence

The codes entered here are used to prepare the connected modem or ISDN terminal adapter for use with the ServSwitch CX with 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 ServSwitch CX with IP is first switched on or whenever the Initialize button is clicked.

Initialise

When clicked, this option sends the characters entered in the Initialization sequence field to the connected modem or ISDN terminal adapter.

Restore Defaults

When clicked, this option resets the Baud rate and Initialization sequence values to their original default settings.

Power control port

Baud Rate

This option configures the speed of the serial connection between the ServSwitch CX with IP and a connected power control unit. The default setting is 9600 as used by the majority of power units. The other communication settings are fixed as: No parity, 8 bit word, 1 stop bit.
