Video Connections
OG-RTR-10/20
Video system interconnects are made by using 75 ohm transmission lines (coax cable).
The device driving the line has a “source” impedance of 75 ohms, the cable has a 75
ohm impedance and the end of the interconnect is internally terminated with 75 ohms.
The accuracy of the termination affects signal level. Use either a 1% or 0.1% termination.
Unused amplifier positions do not need a termination.
Only the outputs which are used need to be terminated.
Input Equalization
The OG-RTR Series HD/SDI 3G Routing Switchers have adjustable input equalization
settings. The factory default setting for Equalization is ON.
There are two states for the equalization setting - active (ON) or bypassed (OFF).
Adjustment to the input equalization is made via the DashBoard software (see next
section).
Reclocking
The OG-RTR Series HD/SDI 3G Routing Switchers also have adjustable output
reclocking settings. The factory default setting for reclocking is ON (automatic).
The
factory default setting for reclocking is Automatic.
The reclocking circuit, when in the automatic mode, will automatically detect and lock to
incoming SMPTE SDI data signals.
If a non-SMPTE data rate is detected, the reclocker will automatically enter the bypass
mode in order to pass the signal without reclocking.
There are two states for the Reclocking setting - automatic (ON) or bypassed (OFF).
Adjustment to the output reclocking is made via the DashBoard software (see next
section).
