2.4 SDA-122i Electrical Installation
When connecting the SDA-122i to external equipment, make sure that all serial digital
connections are point-to-point.
For instance, there must be a point-to-point connection between
the source equipment and the
4:2:2 IN
BNC. If a T-connector is used to connect other equipment,
the maximum specified cable length is no longer valid.
Also, make sure that the input and output serial cables have a maximum length of 275 m (900')
for signals up to 270 Mbps or 180m (600’) for signals up to 540 Mbps.
Refer to Figure 2.2, 2.3 or 2.4 and to the following descriptions for a complete SDA-122i
installation.
••••
4:2:2 IN - serial digital input
Connect a serial digital video signal, conforming to the SMPTE 259M-ABCD standard, or to the
proposed EN50 083-9 DBV-ASI standard (270 Mbps)
to the BNC labeled
4:2:2 IN
. The SDA-122i
will automatically switch to the detected standard.
•
4:2:2 OUT - serial digital outputs
Connect destination equipment to any of the serial digital video output BNCs labeled
4:2:2 OUT
.
All five outputs conform to the SMPTE 259M-ABCD or to the proposed EN50 083-9 DBV-ASI
standard (270 Mbps)
.
