RS232 Universal Serial T-Switch

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 Universal Serial T-Switch 85643 has a settings dump
f u n c t i o n i n t e g r a t e d t h a t a l l o w s y o u t o c h e c k t h e
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 85643.
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 85643
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
