Data
On/off inputs (DI1, DI2)
Input DI1 is used for the printer’s paper function. DI1 is connected to a contact function which is
operated when the paper has been placed in the printer. (Top of form setting).
The DI2 input is used for manual change-over between “default” and “optional” alarm destinations in
connection with the extended alarm routing (cf. section “AKA Alarm Table”).
Light-emitting diodes
- For each communication gate (RS 232/DANBUSS) there are two light-emitting diodes (LED), one
for sending and one for receiving. The diodes are lit, when there is communication to or from the
gateway.
- The status of the ON/OFF inputs and relay-outputs are also indicated with light-emitting diodes.
- There is an LED for power ON
- There is a LED for LON-communication
