Delivery Damage Inspection
Carefully inspect the frame and exterior components to be sure that there has been no shipping
damage. Make sure all modules are seated correctly and have not detached during shipment.
Also, make sure the input buffer modules on the rear panel are secure.
Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from a source
to a destination.
Signal cables — Use only the best quality cables to avoid interference, degraded signal
quality or elevated noise levels.
Sockets and connectors of the inputs and outputs — Use only the highest quality, since
"zero ohm" connection resistance is the target. Connectors should also match the routers
75 ohm impedance to minimize return loss.
Amplifying circuitry — Must have quality performance when the desired end result is
high linearity, low distortion, and low noise.
Distance between the router and devices connected to it — Plays a major role in the final
result. For long distances (over 15 meters) between sources and destinations, special
measures should be taken to avoid high frequency cable losses. These measures include
using higher quality cables and/or adding line cable equalizing amplifiers.
Interference from neighboring electrical appliances — These can have an adverse affect
on signal quality. Balanced signals are less prone to interference, but and signal wire
should be installed away from any power lines, electric motors, transmitters, etc. to
minimize the possibility of electro-magnetic interference.
CAUTION!
Only an authorized Sierra Video Systems technician can service the switchers. Any user who
makes changes or modifications to the unit without the expressed approval of the manufacturer
will void the warranty
Use the proper AC voltage to supply power to the switcher.
Use only the recommended interconnect cables to connect the switcher to other frames.
