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
external +5VDC source voltage to Pin 2.
Remove Jumper JMP 3 and supply an external
Ground (as shown this sample circuit, right).

Seven 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 either +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 exceed +30VDC.
The table on the following page details the GPIO port pin assignments, settings and
functions.
