Diagnostic functions

Starting up an RS232 port is often accompanied by difficulties,
since both the pin assignments as well as the transmission
parameters need to agree in order to enable errorless data
transmission.
The RS232 Multi Computer Adapter 85603 has a settings dump
function integrated that allows you to check the configuration,
which can be quite useful during installation.

Settings dump

As a first test the settings dump integrated in the T-switch can
be used to automatically generate a text which shows all the
programmed settings in the 85603.
The settings dump has multiple functions:
: Testing the data and ground line connection
: Testing the transmission parameters
: Concise output of all settings
: Handshake test for data output from the 85603
To be able to generate the settings dump even under improper
handshake conditions, the dump is even output if the port is
blocked, though at a very slow speed. This means:
: Handshake enabled r Fast dump output
: Handshake blocked r Slow dump output
Hold down the „Dump" key and then connect the T-switch to
its power supply. After releasing the key the port set on the DIL
