Optimizing IR Flasher Levels
Test a few commands for each device before fixing the flasher in
place on the front panel of a device. Since Satellite Receivers and
Cable Boxes are extremely sensitive to IR overload or saturation, you
should test them thoroughly. Put up the cable or satellite
on-screen guide and test the navigation arrows. Compare operation
via RF to the original remote control. Operation should be identical.
If operation is inconsistent or sluggish, lower the IR line output
and/or reposition the flasher.
If you still have sluggish operation, check that the remote control is
set to a particular LINE OUT, rather than ALL. When IR commands
are sent to all the flashers in a cabinet, you can have difficulty
adjusting the IR Output. Reprogram the remote control to send IR
commands only via a specific (1-6) Line Output, then readjust the IR
Line Output level.
1. Connect an IR emitter to each IR output and run the emitter wire
to the front panel of each component. DO NOT STICK the emitter
in place. Adjust the level first.
2. Adjust each of the IR Output levels with the included adjustment
tool for best operation. If the component operates best at minimum
level, but is still operating sluggishly or intermittently, move the
emitter farther away from the component’s IR sensor.
RS-232 Connection
The MRX-8 can operate equipment via RS-232 communication. This
allows discrete serial commands to be triggered from a Total Control
remote to a MRX-8. The signal is then sent to the device over
proprietary URC RS-232 cables. These use either male or female
DB-9 connections with standard pin-outs.
