V1.0/236 V_pro8 Manual
Installation & Configuration
Signal Connections
External Reference Connections
The pro8 provides four external reference connections:
IN - external video reference input. Use this input to connect an analog video reference signal
such as Tri-Level Sync or Black & Burst (BB). The following reference signal standards are
supported:
o
Analog Genlock High Definition Tri-Level Sync (SMPTE-274M/296M)
o
Standard Definition 1V Black & Burst (SMPTE-170M/318M)
LOOP - passive loop-thru output of the video IN (75-ohm termination required). Use this
connection to daisy-chain an external video reference signal in and out of the pro8.
The video IN connection must be properly terminated by fitting a 75-ohm terminator either
on the LOOP connector (if unused), or on the LOOP THRU connector of the last "looped"
device.
OUT - video reference output. Use this connector to feed the system's video reference, as
selected in the user interface, to an external device.
WK - wordclock out. (In a future release, this bi-directional connection will be set to either
wordclock in or out from the user interface).
