Parallel interface information
Centronics 100 interface
6–2
Select the interface for each of the two ports. You select the
actual interface setup using the 4235 LPS menu dialog at the
time of installation. Only one parallel and one serial interface
can run concurrently. You can select one of the following
interfaces:
Parallel:
Serial:
You must fill out Checklist 10 for your parallel interface
selections, and Checklist 11, 12, or 13 for your serial interface
selections, before your Xerox service representative can
successfully install your 4235 LPS.
Parallel communication allows the transmission of data over a
group of wires simultaneously.
Two emulation modes are available with the parallel interface:
one is compatible with Centronics 100 (or equivalent) interface,
and the other is compatible with a DataProducts standard 2260
(or equivalent) interface.
The parallel interface accepts 7–bit or 8–bit ASCII encoded data
at rates up to 200 KBytes per second. EBCDIC and ISO 6937
character encoding schemes assume 8–bit encoding. When
you use XPPM, ISO 6937 selection defaults to 8–bit ASCII.
The Centronics interface uses a 36–pin Amphenol 57–40360
connector. This connector mates with an Amphenol 57–30360
connector.
Note: The connector part numbers for countries other than the
United States may differ from those numbers listed later in this
chapter.
Parallel cable
You need to order a Centronics or DataProducts parallel cable
to connect your host computer system to the 4235 LPS. If you
do not have one, contact your Xerox sales representative to
order one. To make sure the cable is available on the day of
installation, place the order approximately four weeks prior to
the installation date.
Make sure the parallel interface cable is in compliance with
U.S. Federal Communications Commission (FCC) regulations
regarding electromagnetic emissions or any similar regulations
applicable within the country in which you operate your 4235
LPS. The parallel interface cable must also meet the following
specifications:
Data Products or Centronics
SNA / SDLC, asynchronous, or bisynchronous.
