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.
