To install this option, you will need a Philips screwdriv er.
Additional Requirements
Depending on your application, you may need the following hardware to interface the card:
GPI/O A – DB15 Male connector (e.g., StarTech C15PCM) and shielded cabling.
GPI/O B – High Density DB15 Male VGA connector (e.g., StarTech C15HPSM) and
shielded cabling.
COM C – DB9 Male connector (e.g., StarTech C9PSM) and shielded cabling, or a
prefabricated cable (see part numbers and pin out requirements below).
COM D – RJ45 Plug (e.g., Belkin R6G088) and shielded cabling, or a prefabricated
cable (see part number and pin out requirements below).

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.
