Config Menu
The Config menu allows you to select which reference you want to use (Master Ref or External Ref).
The Ref In field reports the type of reference signal coming in. You can also select an option for the
CRC PID control (from 4000 to 8000).
Configured Ref • – Select either Master Ref or External Ref.
Master Ref means that the module is taking its reference signal from the Avenue Frame itself.
External Ref means that the module is taking its reference from an external source, such as an
Avenue 7400 Test Signal and Sync Pulse Generator installed in the Avenue Frame.
Ref In • – Reports the type of reference signal coming in.
Possible values are: No Reference, 525 Composite, 625 Composite, 10 MHz.
CRC PID • – Use the arrow buttons to select a value from 4000 to 8000. You can also enter a
number directly in the field. This is commonly a “set and forget” type of configuration. Use it to
select the PID you want to use for inserting CRCs or Checksum, replacing Null packets.
