INSTALLATION
System Installer must adhere to Article 820-40 of the NEC that provides
guidelines for proper grounding and specifies that the cable ground shall
be connected to the grounding system of the building, as close to the
point of cable entry as possible.
UNPACKING and INSPECTION
Each unit is shipped factory tested. Ensure all items are removed from the container prior to
discarding any packing material.
Thoroughly inspect the unit for shipping damage with particular attention to connectors and
controls. If there is any sign of damage to the unit or damaged or loose connectors contact
your distributor immediately. Do not put the equipment into service if there is any indication of
defect or damage.

HARDWARE INSTALLATION and CONNECTIONS
1. The unit is designed to be rack mounted in a standard EIA 19” rack.
2. Use a 75Ω coaxial cable with RCA connectors to connect the video source (e.g., STB,
DVD, VCR, and Camera) to the unit’s yellow RCA VIDEO INPUT jack (IN1…IN4).
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). 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).
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).
5. Connect the included power cord to the unit’s POWER plug.
6. Connect the power cord to an appropriately rated AC power outlet.
