Pin assignments of the D-Sub connector
Only the signals of the serial interface are connected to the D-Sub-plug directly. If
another signal shall be connected to a pin of the plug, a DIP-switch must be set to the
‘ON’ position.
Whenever an additional signal is connected to the rear panel,
special care must be taken to the configuration of the cable used
with the connector. If pins with TTL level and RS-232 levels are
connected to each other, the circuits on the board may be dama-
ged.
Because the pins 1/4/8 of the D-Sub connector could be used for two different
signals, only one of the switches assigned to these pins might be put in the ‘ON’
position. The table below shows the pin assignments for the connector and the DIP-
switch assigned to each of the signals:

Those signals which do not have DIP-switch assigned are always available at the
connector. All DIP-switches not assigned are reserved and should remain in the
‘OFF’ position.
