How to Program a Digital Slider

  • Digital Slider Switches are programmed just like photocells.
  • Digital Slider Switches must be consecutively addressed and set as “ANALOG/DIGITAL” in the BUS MAP screen.
  • Sliders are assigned to control dimming relays using scenes in an iDIM panel.
  • In order for the sliders to operate dimming outputs. The scene containing those sliders must be the active scene.
  • Trigger 11/Button 11 must be set as “Digital 1” and contains the scene for the “take control” button on the slider switch.




  1. Just like photocells, digital slider switches must be consecutively addressed in order to be seen by micro panels. For example, if you have digital sliders at address 21, 25 and 27 and a photocell at address43, micro panels will only see the first slider switch at address 21. They will not see the other 2 slicers or the photo cell.


In order to have them accessible for controlling dimmers, all photocells and digital slider switches must be addressed one after the other, with no other devices in between. In the above example, setting the three slider switches to address 21, 22, and 23 and the photocell at address 24 would make them all visible to the micro panels.

Remember the absolute limit for the total number of digital slider switches and photocell cards on a single bus is 16. The system will not recognize more than that.


  1. In BUS MAP, set any digital slider switches as “ANALOG/DIGITAL”. This is because the slider itself is an analog input, while the little button below the slider is a digital input.


Programming the Scene:


  1. Using a regular “Scene” type of scene, select the dimming relay/s that you want to respond to the digital slider switch and set it to “PC” for photo cell control.


  1. Enter on “PC” and scroll up/down until you have selected the address of the digital switch you want to use. The first four addresses are always “IN 1” through “IN 4” which are the photocell inputs on the iDIM card itself. Scroll Up/Down past these and the addresses of the photocells/slider on the bus will be selectable.


The digital slider switch will have one or more addresses like “23-1” or “23-3. In this case, the 23 is the actual address on the bus of the slider switch. The -1 or -3 refers to which specific slider on the switch is being followed. In a single slider switch it will always be -1, e.g. “23-1”. For a dual slider witch, the slider on the left is -1, and the slider on the right is -3. Currently, -2 is never used.


So, to set a dimmer to the follow the level of the right-hand slider of a digital slider switch at address 10, the “input” field should be set to “10-3”. (On a Dual Slider Switch always use the same SCENE for both sliders).



You can verify that the correct address was selected by moving the slider while looking at the photocell output. When the slider is moved all the way up, the reading should be 0 (Like a photocell reading total darkness, causing the lights to go to full bright). When it is moved all the way down, he reading will be 1000 (like a photocell reading maximum brightness, causing the lights to dim all the way off).


  1. Fill out the rest of the parameters on the dimming curve screen as follows:


Fade UP: 00:01 Min/Sec

Fade DN: 00:01 Min/Sec


Start: 1

Mid: 500

OFF: 999

Time from OFF: 00:00

Must Turn On @ 998


  1. Repeat steps 1-3 above for each dimming relay that you want to be controlled by a slider. You can have several relays operated by the same slider if you wish.


  1. When you have completed these steps, the lights will now fade up and down in response to the slider switches, BUT this will only happen when the scene you just programmed is the active scene. If another scene is active, moving the sliders won’t have any effect. To Solve this, each slider switch has a small round button below the sliders which activates the correct scene and allows the slider to “take control: of the dimming.



Setting up the “Take Control” button


  1. Go to the PROGRAM SWITCH menu, and select the address of the digital switch.


  1. Scroll down to TRIGGER 11 or BUTTON 11 and press ENTER.


  1. Set the button to ON MODE and program it to control the SCENE you programmed earlier. (For example, if yon programed SCENE 6 in LCP-2, program the button for LCP-2:6 in ON MODE).


  1. Now highlight the words “ON MODE” and press ENTER. On the screen that appears, SCROLL UP or SCROLL DOWN to change the word “ANALOG 1” to “DIGITAL 1”. Exit back to the main menu.



When the digital slider switch is controlling the lights, the small round button will glow red. In order to take control of the dimming relay the user can press the small round button, which should then light up.


*Final Note:


It is a good practice to make sure that there is NO PROGRAMMING assigned to Triggers/buttons 1-10 and 12-14 on a Digital Slider Switch. Since the slider behaves like and is programmed like a photocell, any programming on the triggers can cause the switch to turn relays on and off as the user is sliding the knob up and down (since this is just like a photocell passing up and down through light level set points).
