Operation
Approximately three seconds after powering up, the DA-6804
+
D module should
be fully operational. The module can be set to either local (card-edge) or remote
(CCS network) control, using the
J3 jumpers setting described on page 9 .
The current software version of a DA-6804
+
D module can only be viewed using a
CCS-enabled control panel or a CCS software application. Default settings cannot
be recalled on this module.
Automatic Changeover
The signal at SDI In_1 is distributed to 8 outputs. If the signal at SDI In_1 is lost,
the outputs are switched to SDI In_2 (the module must be able to detect a signal
at SDI In_2 ). Using the Hysteresis parameter, you can set the amount of delay
before the module switches over to SDI In_2 , and before the problem is reported
to CCS.
When the signal returns at SDI In_1 , the outputs automatically switch back to SDI
In_1 from SDI In_2 .
Reclocking
The DA-D can reclock 270 Mb/s SD-SDI signals; the DA-D,
can reclock 270 Mb/s, 1.485 Gb/s, and 2.97 Gb/s SMPTE signals. If the input data
is not at one of those rates, the reclocker function will not function. Instead, the
signal will pass through the module.
