HARDWARE INSTALLANTION and CONNECTIONS
1. The unit can be rack mounted in a standard EIA 19” rack. Attach the rack mounts
if the unit is to be installed in a rack.
2. Use a 75Ω coaxial cable with RCA connectors to connect the video source (e.g.,
CATV, DVD, VCR, Camera) to the unit’s yellow RCA VIDEO INPUT jack
(IN1…IN4 depending on the CSD model).
Repeat this step for each video source connection.
It is highly recommended that quality coaxial cable and connectors be used for all
video source connections.
3. Use RCA cables to connect the audio source to the red / white AUDIO L and
AUDIO R INPUT jacks (IN1…IN4 depending on the SCDM model). Use the red
and white jacks for audio input or either one for a single input.
Repeat this step for each audio source connection.
Be sure the video and audio connections for each source are consistent with the
unit’s inputs (IN1…IN4 depending on the SCDM-SD model).
It is highly recommended that quality cables and connectors be used for all audio
source connections.
4. Use a quality 75Ω coaxial cable with “F” connectors from the unit’s RF OUT jack
to the distribution system (combiner or reverse splitter) or directly to a
television.
5. Connect the included 12VDC 3A power supply to the unit’s DC 12V POWER
jack.
6. Connect the 12VDC 3A power supply to an appropriately rated AC power outlet.
