For direct inputs –
Default Configuration JMP2 and JMP3 installed.
Uses the printer’s +5VDC and Ground to
supply the devices interfacing to the GPIO
inputs (as shown in the sample circuit, right).

For isolated inputs –
To provide galvanic isolation for the GPIO
inputs, remove Jumper JMP 2 then supply an
ex5VDC source voltage to Pin 2.
Remove Jumper JMP 3 and supply an external
Ground (as shown this sample circuit, right).

dedicated outputs
are available for control, warning, and error functions.
These open-collector outputs have slew-limited signal-edge rise and fall times to
prevent cross talk in the cabling. Optional 10K ohm pull-up resistors, tied to a
common point for use at 5 or +24 VDC, are available via Jumper JMP 1.
For +5VDC, on JMP1 place a jumper across pins 1 and 2. For +24VDC, on JMP1 place
a jumper across pins 2 and 3.
Note:
If external pull-ups are used (that is, without Jumper JMP1 installed),
ensure that the applied external voltage does not 30VDC.
The table on the following page details the GPIO port pin assignments, settings and
functions.
