An external DMX dimmer seems to soften e.g. a fire effect. It looks bad. What is wrong?2017-08-31T01:10:37+02:00

The dimmer curve is obviously not set to “linear”. Please change the dimmer curve of all power outputs to “linear” at the DMX dimmer.

Check it by using a tungsten lamp at the power output of the LFXHub. Also note you should disable any pre-heat function.

Assign DMX-channels to an RC4 dimmer2022-05-05T22:41:21+02:00

The DMX channel assignment for a DC output is identical for all RC4 Magic 2.4 GHz, LumenRadio and W-DMX receivers according to the ONETOUCH procedure.

This procedure requires the dimmer, a transmitter (DMX tester or a DMX control desk) and a 5-pin DMX cable.

A bent paper clip is used to press the buttons behind the oval openings.

Transmitter and receiver must be coupled, the DMX signal must be present at the dimmer.

Procedure:

  1. Set the levels of all channels on the DMX transmitter to zero.
  2. Send the DMX channel on the DMX transmitter that is to be assigned to the first channel of the receiver (SetA).
  3. The level of this DMX channel determines the DMX address and the dimmer curve according to the table below.
  4. Using the paper clip on the receiver for channel “DIM A”, briefly press the “SET A” button behind the oval opening once.That’s it. If the assignment was successful, the LED (the monitor for channel DIM A) should now be on/dimmable by the DMX tester directly next to the oval opening..

Change digital persistance2022-05-05T17:01:57+02:00

Change digital persistance for LEDs with ISL dimmer curve

The inertia simulation (digital persistance) can be changed for all RC4 wireless dimmers. This changes the response time of the LEDs when dimming.

This change makes sense when the optimal value for fast response in combination with soft dimming of LEDs is required.

Factory setting is “Medium”

A DMX signal must NOT be present!

  1. Each long press of “SetC” (“OPTC” for LumendimM2) advances one option at a time. After option 7, option 1 is selected again.
  2. Feedback is given by the flashing pattern of the lamps connected to DimA and DimB, or of the output display LEDs.
  3. As soon as the flashing pattern appears, the “SetC” button can be released.

Change private ID on RC4Magic dimmer2022-05-06T10:11:46+02:00

Several RC4 Magic systems can be used simultaneously at the same location.

For this purpose, different private IDs must be used.

There are four IDs available for each RC4 Magic 2.4 GHz gear: ID0, ID1, ID2, ID3 (public ID)

Change the ID on the receiver and transmitter DMXio/DMXio-HG (see label on the unit):

  1. Disconnect the dimmer/transmitter from the operating voltage
  2. Press and hold the “SetA”> ID0, “SetB” > ID1, “SetC” > ID2 or the public “SetD” >ID3 (public) key.
  3. Apply operating voltage > flashing indication of which ID is used directly after power-up: > ID0: LED “RFcon”; ID1: “COP”; ID2: “RFcon” and “COP” flash together, ID3 (public): “RFcon” and “COP” flash alternately > release key.

By default ID0 is selected if reset to factory settings is accomplished.

Change PWM Frequency on a dimmer2022-05-06T09:22:04+02:00

PWM Frequency selection is a Long-Press Button Feature, and the selected frequency is confirmed using patterns of two LEDs.

To cycle through available PWM frequencies:

Ensure live DMX data is streaming in by either wire (miniplug input) or wireless. If DMX data is not streaming, the Set buttons act as dimmer bump buttons only.

  1. Long-Press SetB
  2. When the LED blink pattern appears, release SetB.
  3. The next PWM frequency is now selected for all dimmers on the device and saved.

The LED blink pattern of DimA and DimB outputs indicates the frequency as outlined below. Each long-press of SetB advances to the next frequency.  Advancing from the last option returns to the first option:

  • Option 1: 615Hz (default): DimB > DimA > DimA
  • Option 2: 1250Hz: DimA > DimB > DimA
  • Option 3: 5kHz: DimB > DimB > DimA
  • Option 4: 10kHz: DimA > DimA > DimB
  • Option 5: 20kHz: DimB > DimA > DimB
  • Option 6: 40kHz: DimA > DimB > DimB

RC4 dimmer factory reset2022-05-06T10:15:25+02:00

Performing a Factory Reset :

If someone else has used your dimmer, or you just want to get back to a known configuration, performing a factory reset is easy:

  1. Power on the device. The green COP indicator will be blinking.
  2. Press and hold Func, briefly tap (press and release) the SetABC (for 6 channel dimmers) or SetA (for 2 and 4 channel dimmers) button, then release Func. Four indicators will blink to confirm that factory settings are restored.

NOTE: This does NOT affect transmitter linking.

PRO TIPS: Bending a single paper clip into a U shape will enable you to easily reach and press both buttons together. If you are not sure what mode or setting you may have selected, you can always get back to a known starting point by returning to factory defaults.

Which wireless standard should I use?2017-09-11T21:27:19+02:00

First of all you need to check if there are any existing wireless networks.

If no, the best choice is the RC4Magic series. It provides the most number of product variations for virtually every application. Alternatively choose Lumenradio products or the W-DMX standard.

Please get a overview of the different standards.

If yes, this shouldn´t be a problem but you need to consider some things. Please contact us for assistance.

Why should I prefer the LFX Tools instead of the built-in effects engine of some LED lamps?2017-08-31T01:38:39+02:00

The LFX Master DMX and LFXHub use high resolution flicker CURVES with sequential dimmed values.

All built-in effect engines of LED fixtures use random patterns of a variation of fixed values.

For that reason all “organic” effects like fire, candle, welding, lightning and TV take advantage of the pre-programmed flicker curves with 24 fps resolution which ensures a natural look.

Even the LFX Master dim uses the same quality of flicker curves as used in the LFXHub and LFX Master DMX.
