Appendix D: Interface Data
Interface boards may vary in
design.
Technical data
* The transmission format of
7 bits without parity is not
valid.
D-22
Coresident RS-232C /
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.
The following pages contain information about the correct jumper
assignment and the correct menu selections for each mode as well
as general technical details and information about transmission
protocols.
