Trusted TM Processor Interface Adaptor Module - T812X
Issue 5 Jan 2006
DESCRIPTION
The Trusted
TM Processor Interface Adaptor T812X provides easy access to
the communications ports of the Trusted TM TMR Processor in the Trusted TM
Controller Chassis for Peer to Peer communications, DCS and other links,
networked PCs etc. The Adaptor also supports fault/fail and diagnostics
connections to the Processor, and connection facilities for IRIG B time
Synchronisation facilities, as well as enabling the user of Modbus Master
facilities on the T8151 Communication Interface Card.
The Adaptor comprises a printed circuit board (PCB) on which the
communications ports are mounted. The PCB also supports two 48-way
DIN41612 E-type connectors which enables the Adaptor to be plugged into
the Trusted
TM TMR Processor Module input/output (I/O) connectors (Active
and Standby) at the rear of the Trusted TM Controller Chassis. The
communications ports available from the Adaptor are RS485 (Port 1) and
RS422/485 (Ports 2 and 3). The Ports are accessed via Phoenix contact
2.5mm pitch connectors.
Fault/fail, diagnostic and PSU shutdown monitor, and IRIG B time
Synchronisation signals are also available via Phoenix connectors.
A complete set of connectors mentioned above are allocated to both the
Active and Standby processors.
Termination resistors for RS422/485 communications are selectable via
links. These are mounted on the PCB and are the only configurable items
which require setting up before using the Adaptor.
When the Adaptor is plugged into
the I/O connector on the rear of
the Trusted
TM Controller Chassis,
it is mechanically latched in
position. Release buttons are
provided to enable the user to
unplug the Adaptor as required.
