Current Loop Interface
Current Loop Interface
The arrangement of a short-circuit jumper on the printed circuit
board determines whether this interface board is used as RS-232C
or Current Loop interface. Both modes allow for three transmission
protocols. The protocols are determined by the arrangement of
jumpers or can be selected in the printer menu.
