Outputs
Via signal outputs it is possible to demand various operating modes of the printer.
The signal outputs are made available vial two 9-pin D-Sub-sockets (OUT1) at the rear of the Control
Unit. They consist of optointegrator semiconductor lines which are switched through res. blocked out
corresponding to the different operating modes.
The maximum allowed current in a semiconductor line is Imax = 30 mA.
