RS-422 Output Module
This section provides operating instructions and software provisioning procedures
for the RS-422 Output module (part number 23413287-000-0) designed for use in
the SSU-2000e Synchronization Supply Unit.
Functional Overview
The RS-422 Output module generates 10 balanced square-wave outputs (TTIP and
TRING signal pairs) and 10 single-ended (Ring) square-wave outputs. Each output
can be turned off independently of other ports; relays on each output disconnect the
driver output from the output pins. A squelch feature turns off selected ports when
the input signal falls below predetermined quality levels.

On (Green) = Source C is the selected source clock
On (Amber) = Faulty or missing source C clock
Off = Source C is ignored or good and not selected
On (Green) = Source D is the selected source clock
On (Amber) = Faulty or missing source D clock
Off = Source D is ignored or good and not selected
On = Module has detected one or more faulty outputs
Off = All output signals are good
