FEDERAL COMMUNICATIONS COMMISSION

AND

CANADIAN DEPARTMENT OF COMMUNICATIONS

RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency

energy and if not installed and used properly, that is, in strict

accordance with the manufacturer’s instructions, may cause

interference to radio communication. It has been tested and

found to comply with the limits for a Class A computing device

in accordance with the specifications in Subpart J of Part 15 of

FCC rules, which are designed to provide reasonable protection

against such interference when the equipment is operated in a

commercial environment. Operation of this equipment in a

residential area is likely to cause interference, in which case the

user at his own expense will be required to take whatever

measures may be necessary to correct the interference.

Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to

operate the equipment.

This digital apparatus does not exceed the Class A limits for radio

noise emission from digital apparatus set out in the Radio

Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques

dépassant les limites applicables aux appareils numériques de

classe A prescrites dans le Règlement sur le brouillage

radioélectrique publié par le ministère des Communications du

Canada.

1.0 Specifications

S↔P (SERIAL↔PARALLEL) CONVERTER (128K)

The S

↔

P (Serial

↔

Parallel) Converter (128K) is a serial-to-parallel or

parallel-to-serial converter (conversion direction is user-selectable). It

operates at speeds ranging from 600 bps all the way up to 76.8 Kbps and

has 128K of buffer memory, which is ideal for most ordinary print jobs and

other types of file transfers.

The Converter supports a wide variety of baud rates, three types of data

formats, and either hardware or software (X-ON/X-OFF) flow control, so it

works with many kinds of equipment and applications. You can quickly

and easily choose the settings you want with an external DIP switch. This

switch also has positions that allow you to select the conversion direction

and a self-testing mode. You can choose whether the Converter functions

as DTE or as DCE by moving an external slide switch. And by pushing an

external, recessed pushbutton, you can reset the Converter if anything goes

wrong.

The S

↔

P Converter’s parallel port has a DB25 female connector. Its

serial port has an RJ-45 female connector, so from there to your serial

device you can run unshielded twisted-pair cable with RJ-45 male

connectors. Modular adapters are available to complete the UTP

connection to your serial device if its serial port isn’t RJ-45.

The Converter has its own power supply, so it won’t draw power from the

devices it connects. All the energy in the communication lines goes toward

sustaining communications.

Using the Converter’s self-test mode, you can verify that your Converter

is working properly and that its cable links to your devices are intact before

any operation.

You can use two S

↔

P Converters in series as parallel distance extenders

by setting the first for parallel-to-serial conversion and the second for serial-

to-parallel. This will increase maximum one-way parallel transmission

distance from 20 feet (6.1 m) to as much as 540 feet (164.6 m).

2.0 Introduction

CHAPTER 3: Installation

3.1 What You’ll Need

Before you attach any cables or turn anything on, make sure you have

everything necessary to set up your S

↔

P Converter (128K) system.

Each S

↔

P Converter comes with its own power supply and a 6-foot

(1.8-m) flat satin cable with RJ-45 male connectors. This cable can connect

the Converter to an RJ-45 serial port—or to a modular adapter attached to

a different type of serial port—on a nearby device.

What other equipment is necessary depends on whether you’re using a

single Converter

for parallel-to-serial conversion or serial-to-parallel

conversion (see the list in

Section 3.1.1

)ora

pair of Converters

as parallel

distance extenders (see the list in

One parallel cable

For

parallel-to-serial conversion:

Cable running from the Converter to a

PC’s parallel port should be fully pinned straight-through DB25-male-to-

DB25-male extension cable, up to 20 feet (6.1 m) long, that does

not

have

Pin 1 tied to the shield. Our product code for this cable is ECN25C.

For

serial-to-parallel conversion:

Cable running to a printer’s parallel

port should be standard IBM®parallel printer adapter cable. Our product

code for this cable is EYN600.

B. If the Converter is within 6 feet (1.8 m) of the serial port you need to

connect, you can use the flat satin cable that came with your unit.

Otherwise, you’ll need

one serial cable

Cable running from the Converter to the serial port of a device that’s

between 6 feet (1.8 m) and 50 feet (15.2 m) away should be RJ-45-male-to-

RJ-45-male unshielded twisted-pair (

not

flat satin!). Our product code for

this cable is EYN730MS-MM. If you need to connect a serial port further

away than 50 feet (15.2 m), contact us for extended distance data cable

(“EDDC”), one or more modular adapters, and the maximum cable length

you can run (this will depend on the speed of your serial device).

CHAPTER 3: Installation

C. If the serial port you need to connect is not an RJ-45 female, you will

also need

one modular adapter

For

parallel-to-serial

conversion: To connect RJ-45 UTP to a printer’s

serial port, use an RJ-45-female-to-DB25-male adapter pinned as in

Figure 3-1. Our product code for this adapter is FA080-R2. Refer to

Figure 3-3 for a typical system setup using this adapter.

For

serial-to-parallel

conversion: To connect RJ-45 UTP to an IBM

PC/XT™ type computer’s serial port, use an RJ-45-female-to-DB25-female

adapter pinned as in Figure 3-1. Our product code for this adapter is

FA081-R2. To connect RJ-45 UTP to an IBM AT®type computer’s serial

port, use an RJ-45-female-to-DB9-female adapter pinned as in Figure 3-2.

Our product code for this adapter is FA082-R2. Refer to Figure 3-3 for

typical system setups using these adapters.
