OG-3GDA-1x9
For the OG-3GDA-1x9, the incoming SD, HD or 3G signal is distributed to each
of the nine 3G-SDI outputs, allowing the same signal to be sent to multiple
destinations simultaneously.
If the incoming SD, HD or 3G signal is one of the five SMPTE rates (270 Mbps, 1.483
Gbps, 1.485 Gbps, 2.966 Gbps, 2.970 Gbps), the signal will be reclocked, and both
the SMPTE Lock LED and Signal Present LED will illuminate. Otherwise, if a non-
SMPTE input is detected, the signal will bypass the reclocker and only the Signal
Present LED will illuminate.
