COM C (J4)
Serial Port C functions as an RS-232 interface or as a dedicated device interface, according to jumper
setting configurations indicated below:
COM C Jumper Setting Functions

Note: Jumper settings will override most printer menu settings; however, if COM C jumpers are set for RS-232
communications with both the RFID and Linear Scanner options menu-enabled the printer will
automatically assign the Linear Scanner to COM C (J4).
COM D (J3)
Serial Port D is an RS-232 communications interface.
Applicator Interface Card (Version 2) Indicators:
Verification of settings and activity monitoring of the GPIO ports is available via displayed and printed information;
see the printer Operator’s Manual for menu information:
Note: Unused, non-connected inputs and outputs will have an indeterminate state and assume a value of 1 or 0.
Indicators: Real-time incoming (IN) and outgoing (OUT) signal activity can be observed via LEDs on the card
bracket. Sampled every millisecond, these LEDs change color with a corresponding change of signal state.
