GPI/O B (J2)
Six unassigned inputs are designed to interface to open-collector outputs. These
inputs require no external pull-ups and blocking diodes allow the use of totem pole
outputs from +4.5 to + 26 VDC. Optical isolators are available to provide isolation. Two
print control interface circuit examples are given below.
For direct inputs:
Use the printer’s +5VDC and Ground to supply
the devices interfacing to the GPI/O B inputs (as
shown, right).

For isolated inputs:
To provide galvanic isolation for the GPI/O B
inputs, remove jumper JMP 11 then supply an
external +5VDC source voltage to Pin 1, and
remove jumper JMP 10 then supply an external
Ground to Pin 6 (as shown, right).

Six unassigned outputs are programmable and slew-limited. Optional 10K ohm pull-
up resistors, one for each of the output lines, can be used at either +5 or +24 VDC via
jumpers JMP 2 – 7.
;
If external pull-up resistors are employed (that is, when Jumpers JMP 2 - 7 are
not installed), to avoid damage ensure that external voltage does not exceed
+30VDC.
The table below details the GPI/O B pin assignments, settings and functions.
