COMPLIANCE DECLARATIONS

PLEASE OBSERVE THE FOLLOWING SAFETY

PRECAUTIONS AS OUR PRODUCTS CONT AIN

CLASS I LASER PRODUCTS

WARNING

Do not disconnect the fiber optic connector while the unit is powered
up. Exposure to laser radiation is possible when the laser fiber optic
connector is disconnected while the unit is powered up.

Although the fiber optic connectors in this product emit only Class 1
energy that is below the levels considered to be hazardous, one should
never stare directly into a fiber optic connector or an unconnected fiber
end unless one can be certain that no exposure to laser energy could
occur.

CAUTION

This manual is intended for use by trained service personnel. The use
of controls, making adjustments, or performing operations other than
those specified may result in hazardous radiation exposure.

The following label or equivalent is located on the surface of laser products.
This label indicates that the product is classified as a CLASS 1 LASER
PRODUCT.

Fiber Optic 8/16 Channel RS-422/RS-232 Data Transmission System

BCI 520E User’s Manual

1.0 PRODUCT DESCRIPTION

The BCI 520E Series is a low-cost, high performance Digital Fiber Optic
Multiple RS-232 or RS-422 Channel Data Transmission System, providing
simultaneous transmission of multiple serial data channels, and offering
a high channel density solution for low-bandwidth applications.

The standard 520E system is designed to transport sixteen asynchronous
RS-232 data channels, or eight asynchronous RS-422 data channels,
over long distances with a single or pair of singlemode or multimode
fiber. Data rates for the 520E are up to 128 kbp s for each RS-232 channel,
or up to 750 kbps to 1 Mbps for each RS-422 channel. Lastly, the
520E’s can be configured for various distances depending on the
application.

The 520E provides front panel LED indicators for power and optical link
status.

The 520E is available in a standalone or card cage format, thereby
accommodating multiple configurations, depending on the application.

2.0 SETUP

The BCI 520E Series units are used in pairs. One 520E transceiver unit
is located at the near end and connected through two optical fibers to
an identical 520E transceiver located at the far end of the link. Each
unit provides an electrical interface connector for the RS-232 or RS-422
data signals. Connections are one to one between both units. Figure 2-1
depicts a typical installation.

Figure 2-1

520E Setup

2.1 Mounting

Before installing the units into your housing, make sure there is
enough space to pull and connect both the electrical and optical
cables without stressing them beyond the manufacturer’s
limitations (also known as the bend radius minimum). Rack
mount kits are available for half-size versions only , with internal
power supplies.

2.2 Cabling and Connectors

In order to setup the BCI 520E properly , make sure to observe
the following instructions when installing the proper cables. The
520E requires two parts to the cabling setup: the electrical and
the optical.

2.3 Electrical Cable Connection

The only available cable connections on the electrical side is
for the RS-232 or RS-422 connections.

2.3.1 Data Channel Connection

Use the following steps to connect to your data equipment.

1. Before connecting your user supplied equipment, wire
up the proper cabling to connect from the 520E to the
end-user’s equipment, observing T able 2-1 pinout s for
the various RS-232 or RS-422 applications. Note: The
520E units require a cable with a 78-pin interface in
order to convert the pinouts over to their respective
RS-232 or RS-422 equivalent. The pinouts for the 78-pin
connector is illustrated in Figure 2-2.

2. At the local end, connect one end of a serial computer
data cable to the user’s data device and the other end
to the 520E unit’s 78-pin connection. Repeat this step
for each RS-232 or RS-422 channel.

3. Repeat steps 1 and 2 for the far end observing the pinouts
for the 78-pin with their respective connector.

4. The following parts and tools are used for this 78-pin
connector.

a. D-Sub 78-pin, Mfg. P/N 180-078-172-000 or BCI

P/N 30304-0878.

b. Male Crimp pin, Mfg. P/N 180-001-170-001 or BCI

P/N 30060-0085.
c. Crimp tool from Paldin 1600 Series.
d. Metalized backshell for DB 78-pin, Mfg. P/N

979-050-020-121 or BCI P/N 30060-0979.
e. D-Sub 78-pin with solder cup pins, Mfg. P/N

180-078-102-01 1 or BCI P/N 30060-4878.
