The blue connector does not have the extended tail or the
included tie-wrap.
Do not tin the power supply leads before installing in the
direct insertion connector. Tinned wires are not as
secure in the connectors and could be pulled out.
After making any adjustments to the BUC 102, either
via the front panel controls, SIS commands, or the
Extron Audio Products Control Program, wait at least
10 seconds after making those changes before
disconnecting power to the BUC 102. Failure to
observe the 10-second timeout may result in those
adjustments not being saved.
Your BUC 102 may have shipped with a blue captive
screw connector. This blue connector can be plugged
into either a blue or an orange power receptacle.
The ideal length of exposed (stripped) copper wire
for the blue connector is 3/16" (5 mm).
