3.7. Interconnection
The following figure shows the HVD3001C04 module rear board connector layout.
Rear view of the HVD3001C04
The HVD3001C04 module includes two inputs (IN A, IN B) and four outputs per section
(OUT0-A/LOOP-A to OUT3-A, OUT0-B/LOOP-B to OUT3-B) for 3G/HD/SD-SDI digital video.
When configured as a single channel one input, eight output distributor only input IN A
is used.
The HVD3001C04 modules includes bypass relays on the rear board that connect the
signal at the IN A input to the OUT0-A/LOOP-A output and also from the IN B input to the
OUT0-B/LOOP-B output in case of power loss or extraction of the module.
The HVD3001C04 also includes rear-panel optical inputs and outputs (B-IN and A-IN
OPTICAL, A-OUT and B-OUT OPTICAL) for SDI video.
The HVD3001C04 also accepts 270 Mbits/s DVB-ASI signals. These signals are polarity
sensitive, and because half of the outputs of the distributor are polarity inverted, only
the non-inverted outputs marked as OUT0, OUT2 and OUT4 can be used in section A and
OUT1 and OUT3 in section B.
