Jupiter Systems
CAUTION For Jupiter-controlled routers, replacing an HO-33120 output board that is
part of a protected path scheme will cause a momentary loss of video on the
active output. In other words, video will be lost on the board not being
replaced. This interruption will continue for several seconds. Maintenance
personnel should therefore plan on such replacement only when the pro-
tected output is not being used on air.
This interruption time is equivalent to the protected path fail-over time. It
is also a function of the control system refresh. When a board is replaced in
the system, the outputs do not become active until switched by the control
system refresh. Once a board is replaced in the system it must be polled by
the Com Bus and be found to be part of a protected path before the output
will be disabled or enabled appropriately.
