ADC-SDI

4 Connections

The ADC-SDI has its own connector module: ADC-SDI-C1, mounted at the rear of the sub-
rack.

4.1 Mounting the connector module

If the connector module is purchased separately, it should be mounted as described in the
user manual for the sub-rack frame FR-2RU-10-2. This manual is also available from our
web site: http://www.network-electronics.com/

4.2 Correspondence of connectors and signals

The ADC-SDI-C1 connector module has 7 BNC's:
Ch1
Ch2
Dup1
Dup2
SDI1
SDI2
SDI3
The analogue input BNC's can be used with CVBS, one at a time, or together with S-Video
Luma on Ch1 and Chroma on Ch2. SDI1, SDI2 and SDI3 are equivalent SDI outputs.
The backplane has a DIP-switch with two individual switches, as shown in Figure 2. Switch 1
is used to turn on/off 75 ohm termination on input channel 1, and switch 2 is used to turn
on/off 75 ohm termination on input channel 2.
The analogue input must be terminated somewhere to enable the video decoder
chip.
