Product Overview

Trusted Communications Interface Product Overview The Trusted® Communications Interface (CI) is an intelligent module that provides a range of communication services for the Trusted Controller, minimising communication loading of the Triple Modular Redundant (TMR) Processor. A user-configurable module, the CI can support multiple communication media. Up to four Communications Interfaces (CIs) can be supported by a Trusted System.

The Trusted Expander Interface Adapter Unit T8312 comprises four, or seven 12-pin ODU connectors (dependent on type of Unit), a printed circuit board (PCB), a 96-way C type connector which plugs into a double 96-way connector assembly designed to be connected to the Trusted Expander Interface Modules resident in the Controller Chassis. The Unit is contained within a metal enclosure and is designed to be clipped onto the Controller Chassis rear connectors. A release button is provided to enable the Unit to be disconnected.
