Step 1: Configuring the Hardware

Configure the card to meet your interfacing requirements by arranging hardware jumpers,

as described in the following procedure:

CAUTION

Always wear a wrist strap and follow standard ESD prevention measures

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 open-

collector outputs, these inputs require no external pull-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.
