Determining and Setting Router Signal Levels
Signal levels are preset at the factory and tested during manufacturing, determined by cus-
tomer input and requirements. The installation of your new Utah-400 Router should not require
any signal level changes to operate after the new installation.
By definition, a signal level represents distinct elements of the broadcast system. These indi-
vidual elements include, but are not limited to, High Definition Video, SDI Video, Digital Audio,
Analog Video, Analog Audio and Data Routers. For additional information relating to signal
levels, refer to the Introduction, Page 1-7.
Should you ever need to change the signal level of your router it is useful to determine:
•
What new signal level is required.
•
If other signal levels will have to be modified to accommodate the new signal level.
•
Additional encoding requirements necessitated by the change.
To change the Utah-400 Router Signal Level:
Note: The Utah-400 crosspoint board must be powered down or reset for it to
recognize any configuration changes made to the dipswitches. If the
router has on-air signals present do not attempt a reconfiguration until it
can be completed during the off-air time slots.

If the Utah-400 is not powered down, disconnect it from the power source.
