W&T Expanded services of the Com-Server
Subject to error and alteration
25�4 Up-/downloading configuration data
Factory default: 8003/TCP=read, 8004/TCP = write
These services allow you to read out the configuration data
for the Com-Server stored in the non-volatile memory and
send it to another Com-Server. Especially when installing a
large number of Com-Servers having the same settings this
methjod eliminates having to open a Telnet configuration con-
nection for each individual unit.

services can be reached is configured and deactivated

Use of the system password
If a system password has been configured (see section Basic
Configuration of the Com-Server), this must be null-termi-
nated (=[password] + 0x00) and sent to the Com-Server via
the Control Port within 2s after a connection has been suc-
cessfully opened. If the Com-Server does not receive a correct
or even any password within this time, it sends the message
PASSWD? followed by a null byte (0x00) to the client and clo-
ses the TCP connection.
If no system password is configured, the Com-Server expects
or sends the configuration data directly after the TCP connec-
tion has been established.
Reading out the configuration data on port 8003
All the client application needs to do is open a TCP connec-
tion to Port 8003 of the Com-Server. The Com-Server accepts
it, automatically sends its 2048-byte long configuration and
then closes the connection to the client.
The client application can store this data now in a binary file
and use it for downloading to other Com-Servers.
