Manual Configuration

If you are not importing a .vis project, or if you need to set up new LED dimmers manually, you can configure them from scratch using the RS485 tab in the IHC Plugin. This method gives you full control over channel linking, naming, and KNX group object assignment.

Before starting, it is recommended to clear any existing channel assignments to avoid conflicts.

Proceed as follows to configure LED dimmers from scratch:

1. Open the RS485 tab
   In the IHC Plugin, navigate to the RS485 tab to access the LED dimmer configuration.

2. Clear existing channel assignments
   If you are reconfiguring an existing installation, it is recommended to use the Unlink all button first. This sends a broadcast message to all connected LED dimmers, instructing them to clear their channel IDs. This helps prevent issues caused by duplicate or conflicting channel assignments.

3. Start linking the first channel
   Select an unlinked channel from the list and click Link Channel.

   

4. Enter linking mode on the physical dimmer
   A dialog window will appear, instructing you to press and hold both physical buttons on the LED dimmer until they start blinking. This puts the device into linking mode.

   

5. Confirm the channel selection
   Press either the left or right button on the dimmer to confirm which channel you want to link. Click Link in the dialog.

6. Review auto-filled fields
   The Channel ID and group address fields are auto-filled. The Channel field will indicate whether you linked the left or right channel.

7. Name the channel and adjust settings
   Enter a custom Name and adjust additional parameters as needed.

   

8. Assign KNX group objects
   You must assign KNX group objects to enable communication between the dimmer and other devices. You can select existing objects or create new ones using the Add new object option.

   Assign the following group objects:

   • Status: 1-bit group object used to send ON/OFF commands to the LED dimmer channel.

   • Dimming: 4-bit group object used to send dimming commands (e.g., dim up/down).

   • Level: 8-bit group object used to send specific brightness levels (0–100%).

   • Level feedback: 8-bit group object used to receive brightness level updates from the dimmer.

   • Status feedback: 1-bit group object used to receive ON/OFF status updates from the dimmer.

9. Save the configuration
   After completing the configuration, click Save changes.

   

10. Repeat for additional channels
    Continue configuring other dimmer channels by repeating the linking and setup process.
