Serial Port C functions as an RS-232 interface or as a dedicated device interface, according
to jumper setting configurations indicated below:

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).

Serial Port D is an RS-232 communications interface.
Indicators:
Real-time incoming (IN) and outgoing (OUT) signal activity can be observed via LEDs on the
card bracket. Sampled every millisecond, color change occurs with a corresponding change
of signal state.
Unused, non-connected inputs and outputs will have an indeterminate state and assume a
value of 1 or 0.
