External Sync Source
JP900 selects an external sync source. Position A selects the loop
through frame reference. Position B selects a terminating
reference input used for this module only.
NOTE:
JP900 does not have to be set unless GBR Format Internal/
External Sync Selection (JP103) is in the External Ref position.
If a common reference can be used for all modules in the frame
which require a reference, JP900 should be placed in Position A.
Alternately, if a separate reference is required, JP900 should be
placed in Position B. For example, if modules needing 525 and 625
line standard references are both present in a single frame,
position B should be used on module needing the alternate sync
source.
illustrates the location and settings of JP900.
