Introduction
This document provides general information for the Trusted
TM
Processor Interface Adaptor T812x.
The Adaptor provides easy access to the communications ports of the Trusted
TM
TMR Processor
(T8110B) in the Controller Chassis for DCS and other links. The unit is also used to enable a number
of extended facilities available on the Trusted
TM
TMR Processor including facilities for the reception of
IRIG B time synchronisation signals, enabling the use of Dual (‘enhanced’) Peer to Peer and enabling
the Trusted
TM
system to become Modbus Master.
Features

TM
TMR
Processor.
