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 CPU IP.
Modem port
PPP server IP address / PPP client IP address
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.
Initialization sequence
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
When clicked, this option sends the characters entered in the Initialisation
sequence field to the connected modem or ISDN terminal adapter.
Restore Defaults
When clicked, this option resets the Baud rate and Initialisation sequence values
to their original default settings.
Power control port
Baud rate
This option configures the speed of the serial connection between the CPU 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.
