Optimizing IR Flasher Levels
Test a few commands for each component before fixing the flasher
in place on the front panel of a device.
Since TiVo, Satellite Receivers and Cable Boxes are all extremely
sensitive to IR overload or saturation, you should test them
thoroughly. Put up the on screen guide and test the navigation
arrows. If operation is inconsistent or sluggish, lowerthe IR line
output for port 1 only and/or reposition the flasher.
If you still have sluggish operation, make sure IR routing is used
rather than ALL. When IR commands are sent to all the flashers in a
cabinet, you can have difficulty adjusting the IR Output. Program
URC Accelerator to send IR commands only via a specific IR port
(1-4), then readjust the IR Line Output level.
Connect an IR emitter to each IR output and run the emitter wire to
the IR receiver of each component. DO NOT STICK the emitter in
place yet. Adjust the LEVELon IR port 1 or adjust the emitter
PLACEMENT for ports 2-4 until the component responds to IR
commands then stick the emitter in place.
IR Outputs: These ports can be as discrete, ‘routed’ outputs that
only send IR commands to the specific component that each
emitter is attached. This assures accurate control in that a given
component’s commands are routed only to its dedicated IR output
and emitter, preventing IR oversaturation from multiple emitters
flashing at the same time.
