TELEMETRY BYTE ORIENTED SERIAL (TBOS) MANAGEMENT CONNECTIONS
(RJ48)
TBOS operates via RS422, therefore the inputs and outputs are differential pairs. The pinout for the
MANAGEMENT IN port is:
pin 1 - Transmit- (out of TRACER)
pin 3 - T (out of TRACER)
pin 5 - Receive- (in to TRACER)
pin 7 - (in to TRACER)
The pinout for the MANAGEMENT OUT port is:
pin 1 - Receive- (in to TRACER)
pin 3 - (in to TRACER)
pin 5 - Transmit- (out of TRACER)
pin 7 - T (out of TRACER)
The rear panel connectors are on a double-stack RJ45, so the pin numbers are opposite of each other:
A TBOS monitoring system will need to define the following bitmaps to indicate status and alarm
conditions.
