Purpose
Used for making connections to the separately ordered 12VAC
transformer.
Used for connecting to the RS-485 bus.
Used for connecting the printer to the printer interface unit.
Indicates the unit's communication status to the printer as follows:
•
•
Used for setting the communication address on the RS-485 bus.
Insert only if the printer interface unit is located at one end of the RS-485
bus.
Indicates the unit's communication status to the control unit as follows:
•
•
Space is provided for adding a tamper switch, which must be ordered
separately as a 248116 Tamper Kit.
