Output Process Variables
The following table lists the PVs for the output settings used to configure the signal
outputs. These outputs include the external output on the front panel and TTLTRG
N
outputs on the external trigger header. The trigger output PVs are duplicated for each
TTLTRG
N
output. In the following table,
N
is substituted with the appropriate trigger
number (for example: OutTrig1Enable).
