Step 1: Configuring the Hardware
Configure the card to meet your interfacing requirements by arranging hardware jumpers,
as described in the following procedure:
Always wear a wrist strap and follow standard ESD prevention measures
CAUTION
when handling the card.
A) Remove the card from the packaging and then place the card onto a static-free work
area.
B) Set the jumpers on the card (detailed below) to meet the requirements of your
application:
► GPI/O A (J1)
Four dedicated inputs control printer functions. Designed to interface to opencollector outputs, these inputs require no external pu ll-ups, while blocking diodes
allow the use of totem pole outputs from +4.5 VDC to + 26 VDC. Optical isolators
provide galvanic 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 A inputs
(as shown in the sample circuit, right).
For isolated inputs –
To provide galvanic isolation for the GPI/O A
inputs, remove Jumper JMP 9 then supply an
external +5VDC source voltage to Pin 2, and
remove Jumper JMP 8 then supply an external
Ground to Pin 1 (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.
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 below details the GPI/O A pin assignments, settings and functions.

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

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 in the
sample circuit, right).

► COM C (J4)
Recognized by the printer as Serial Port C, COM C functions as an auxiliary RS-232
interface or dedicated device port for the RFID and Linear Scanner options. Pin
assignments for the port are as follows:

Note: Jumper settings override menu settings: If set for RS-232 (default) with
the RFID and Linear Scanner menu-enabled, the printer will assign RFID to
Serial Port B (back plane port J13) and the Linear Scanner to the COM C
port.

Step 4: Configuring the Software Settings
Configure the printer’s m
A) Using the Control Panel, enter the ADVANCED MENU (see the Operator’s Manual for
menu navigation details):
• If using the GPIO A (J1) port, configure the settings to meet the requirements of
your system using the PRINTER OPTIONS GPIO PORT APPLICATOR
menu selection;
• If using the GPIO B (J2) port, refer to your MCL documentation;
• If using the COM C (J4) port for serial communications, configure the it to meet the
requirements of your host system’s serial port settings using the
COMMUNICATIONS SERIAL PORT C menu selection; or,
If using the COM C (J4) port for a dedicated device, enable that device using the
enu settings for the option’s operation.
PRINTER OPTIONS menu selection; and,
• If using the COM D (J3) port for serial communications, configure the port to meet
the requirements of your host system’s serial port settings using the
COMMUNICATIONS SERIAL PORT D menu selection.
B) After entering the desired settings exit the menu system and save your changes. The
printer is now ready to operate using the GPIO option.
