Interfaces
Overview
This chapter describes the host interfaces provided with the printer. The
printer interface is the point where the data line from the host computer plugs
into the printer. The interface processes all communications signals and data
to and from the host computer. Plus, with the Auto Switching feature, you can
configure the printer to accept several interfaces at the same time (see “Auto
Switching Submenu” on page 67).
IMPORTANT
To comply with Electromagnetic Compatibility (EMC) regulatory
requirements all electrical signal interface cables connected to this
printer must be of a minimal quality level, be of the correct length, and
be properly installed.
The RS-232 port and parallel port interface cables must meet the
following specifications:
•
The cable design must be double shielded with a copper braid over
an aluminum mylar foil and not just a conductive foil spiral wrapped
around a drain wire.
•
The shield must terminate coaxially (360 degrees) to a metal
connector housing and not be terminated by just a simple wire lead.
•
The cable length, including connectors, must be 3 meters or less.
•
The cable connector anchor screws must be securely seated into
the printer receptor hardware.
For reference purposes only, two specific Centronics parallel port
cables that have been tested and found to comply with these
requirements are Belkin
®
part number F2A046-10 and Primelogic
®
part
number PLU 2823224. Other electrically equivalent cables are
acceptable.
