Control Inputs and Outputs
By means of a maximum of 16 control inputs and outputs which, in the
following, are also referred to as ports, different functions of the printer
system can be triggered and operating states can be displayed.
The ports are provided by means of a D-Sub bushing (26pin HD) at
the rear panel of the printer system and are galvanically isolated from
protective earth (PE) by means of an optocoupler semi-conductor
route.
Each port can be configured as input and as output. This function
however, is predefined in the printer software and cannot be changed
by the user.
The following parameters can be changed and set by using the menu:
debounce times and high or low active.
