I. All RC4 Series 3 Harmonized Design dimmer devices revert to bump button modeBump button modeWhen an RC4 Wireless Series 3 dimmer does not see a DMX data input, the Set buttons operate as bump buttons. This is called bump button mode.

A. This is useful for testing a dimmer when no transmitter or DMX data source is available.
B. In a LumenRadio CRMX system, DMX data stops streaming if any of these conditions are met:
1. The receiver device is not paired to a transmitter and the blue RF indicator on the RC4 receiver device is off
2. The paired transmitter is not powered on or is out of range and the blue RF indicator on the RC4 device is blinking continuously
3. The paired transmitter is powered on, no DMX data is present at the transmitter input, and the RF indicator on the RC4 is on with short blips off
II. Un-pairing a LumenDimM4 from any transmitter it may have been paired to
A. Using a small tool like a paper clip, hold down the RF button for several seconds
B. The blue LED will turn off, indicating the device is no longer paired to the transmitter
III. When there is no streaming DMX data to a LumenDim device, all Set buttonSet buttonAll RC4 dimmers have a Set button for each individual dimmer output. On a 2-channel device, these are SetA and SetB. A 4-channel device adds SetC and SetD. The most common use of the Set button is to assign a DMX channel and dimmer curve to the associated Dim dimmer using RC4 OneTouch; SetA is […]
Read more »s become dimmer bump buttonsBump buttonsA bump button temporarily turns on a dimmer output for testing. On RC4 Series 3 dimmers, the Set A, Set B, Set C, and Set D buttons act as bump buttons when there is no DMX data signal present. This makes it easy to build and test a prop or set piece without the need […]

A. When bumping a dimmer, the assigned dimmer curve is used
1. For the non-dim curveNon-dim curveSome devices being controlled by a dimmer should only be turned on and off; gradations of dimming are inappropriate. Examples of these kinds are load are relays, solenoids, and pneumatic valves. In cases like this, a non-dim curve is used. The RC4 non-dim curve uses hysteresis to ensure the output will never unintentionally oscillate, even […]

2. For any dimmer curve capable of varying levels, the bump level is 75%
A. Set the Set A buttonSet A ButtonAll RC4 dimmers have Set buttons for each individual dimmer output. The first button is the Set A button. On a 2-channel device these are Set A and Set B buttons. A 4-channel device adds Set C and Set D. The most common use of the Set button is to assign a DMX channel and […]

1. Set A bumps dimmer output A
2. Set B bumps dimmer output B
3. Set C bumps dimmer output C
4. Set D bumps dimmer output D
B. Bump Button Mode is only engaged when there is NO streaming DMX
1. If a dimmer output does not come on or stays on after releasing a bump button, DMX data is streaming and the Set buttons are not in bump button mode
