DESCRIPTION

The Trusted

Fibre TX/RX Unit

T8314 is designed to extend the

Trusted

Expander Bus over

distances of up to 10km. This

enables a Trusted

Expander

Chassis to be located remotely

from the Trusted

system.

It is recommended that if a

remote Expander Chassis is to

located more than 2km from the

Controller Chassis, the route of

the cable is surveyed.

The Expander Bus is extended by

means of a communications link

using a single mode fibre-optic

cable. The Trusted

Fibre

TX/RX Unit converts the

differential signals of the

copper-based Expander Bus to a

fibre-optic signal for transmission

via the single mode cable. Three

totally independent pairs of

Trusted

Fibre TX/RX Units

provide a non-interfering ‘Grey

Channel’ approach to safety.

Six Units are required for each

remote link with three located at

each end. A dual 24V dc power

philosophy is employed allowing

the user to supply each Unit with

dual power feeds.

Individual Units require no

configuration prior to installation

within a remote communications

link. Each Unit operates in a

stand-alone mode allowing

replacement without interrupting

the operation of the Trusted

System.

There are no diagnostics,

available, but the quality of

communications may be checked

by using the main Processor

diagnostics via the Trusted

Diagnostics Interface Utility.
