Local Source IR Control |
Local IR Source Control
Local source control is accomplished by connecting IR emitters to the Alternate Master [IN] of the keypad. Local control is not limited to one source, as many as four IR emitters can be wired in series directly from the keypad. NOTE: Additional resistance will need to be added when running emitters directly from the keypad. Resistance will vary depending on the distance of the run and the size of the wire used. Typical in line resist- ance will range from 50Ω for long runs to 150Ω for short runs. 12V Control voltages for local amplifiers or other voltage sensing devices may also be terminated directly to the keypad’s Alternate Master [IN] using the 12V control and ground. If resistance is not added, control of shared sources may be lost.
Multiple emitters should be con- nected in SERIES!
Most common brands of emitter can be used, however all Emitter output
more consistent levels when con-Home run to CT back panel nected in series. Parallel connec-
tions may work “some of the time”. Series connections are recom- mended for consistent operation!
Standard 2 conductor 16 gauge speaker wire is ideal for long runs from the keypad to a Local TV or device using an IR emitter. Utilizing CAT 5 cable will also work well.
Note: Additional resistance needs to be added when running a flasher directly off a keypad. Resistance will vary depending on length of run usually between (50Ω - 150Ω). The resistor needs to be wired in series with the flashers. This can either be on the + or - side of the connection. You will know if you need addi- tional resistance if the keypad is not able to control the shared sources connected to any of the 9 IR outputs.
