Communications Interface T8151

Issue 6 Jan 2006

FRONT PANEL

DESCRIPTION

The Trusted

Communications

Interface provides the Trusted

Controller with an intelligent

communications interface which acts

as a relay between the Trusted

processor and other systems, i.e. the

Engineering Workstation (EWS) and

third-party systems. This minimizes

communications loading of the

Trusted

Processor.

The module has a Motorola 600

series processor and MPC106 PCI

bridge/memory controller, its

associated memory and glue logic.

There is also a site for a PCI

mezzanine card for future expansion.

The module communicates with the

Trusted

Processor via the

triplicated Inter-Module Bus (IMB).

When polled by the processor, the

module’s Bus Interface 2-oo-3 votes

the data from the IMB, and transmits

back its reply via all three channels.

The module implements

communications processing under the

control of the Trusted

Processor.

Messages received from the

processor, or an external link, are

validated, undergo the necessary

protocol conversion, and are then

forwarded to their destination.

An electrically isolated RS232

diagnostics serial port is provided on

the front panel of the module for

interfacing to the EWS.

The module receives a dual 24V dc

supply from the Controller backplane.

An on-board power supply unit

provides voltage conversion for the

module electronics, supply

conditioning and protection.

Configuration of the module is carried

out using the Trusted

Toolset

running on an Engineering

Workstation. Once configured and

loaded into the Trusted

Controller,

replacement modules are on-line

educated by the TMR Processor.
