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 electrically-isolated inputs –
To provide galvanic isolation for the GPI/O B
inputs, remove jumper JMP 11 then supply an
ex5VDC 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 5 or +24 VDC via jumpers
JMP 2 – 7.
To avoid damage if external pull-up resistors are used (that is, when Jumpers JMP 2 - 7 are
not installed), ensure that the external voltage does not 30VDC.
The table below details the GPI/O B pin assignments, settings and functions:
