6. Matching and Clearing Codes

The EX4S controller supports matching with receivers, other touch panels, and remote controls. Ensure all devices are powered on and correctly wired before proceeding.

6.1. Match Code between Touch Panel and Receiver

Method 1:

1. Power on the receiver and complete step 2 within 10 seconds.
2. Long press the 'MODE' key on the touch panel until the connected lamps flicker.
3. Touch the color circle on the touch panel within 5 seconds. If the lamps stop flickering, the match is successful.

Method 2:

1. Short press the "ID learning button" on the receiver.
2. Long press the 'MODE' key on the touch panel until the connected lamps flicker.
3. Touch the color circle on the touch panel within 5 seconds. If the lamps stop flickering, the match is successful.

6.2. Match Code between Touch Panels (Multi-panel Control)

Assuming touch panel 'B' is to be matched with 'A':

1. Touch the color circle on touch panel 'A' for 5 seconds.
2. Long press the 'MODE' key on touch panel 'B' until all indicators flicker. If the indicator of 'B' stops flickering, the match is successful.

Note: After touch panel 'A' controls the lamps, if 'B' and 'C' are matched with 'A', they can also control the lamps. Connecting touch panels with DMX decoders can also achieve multi-control functionality.

6.3. Match Code between Touch Panel and Remote

Touch panel match up with remote:

1. Long press the 'MODE' key on the touch panel until all indicators flicker.
2. Long press the remote control button. If the indicator light of the touch panel stops flickering, the match is successful.

Remote match up with touch panel:

1. Press the 'I' and 'II' keys on the remote simultaneously. The indicator light will stay on.
2. Touch the color circle on the touch panel. If the remote's indicator flickers twice, the match is successful.

6.4. Clear Code

To clear code between Touch Panel and Receiver:

Method 1:

1. Power on and off the receiver continuously for 5 times.
2. If the buzzer long beeps and the lamps flicker twice, the matching is successfully deactivated.

Method 2:

1. Long press the "ID learning button" on the receiver for 5 seconds.
2. If the lamps flicker twice, the matching is successfully deactivated.

To clear code between Touch Panels:

Press the 'W' key on touch panel 'B' simultaneously for about 3 seconds. If the indicator light flickers several times, the code is successfully cleared.

To clear code between Touch Panel and Remote:

Long press the 'I' and 'II' keys on the remote simultaneously for about 6 seconds. If the indicator light stays on, the code is successfully cleared.

7. Maintenance

• Keep the device clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• Ensure the operating environment is within the specified temperature range (-30°C to 55°C) to prevent damage.
• Regularly check all wiring connections to ensure they are secure and free from damage.
• Avoid exposing the touch panel to excessive moisture or direct sunlight.

8. Troubleshooting

If you encounter issues with your EX4S controller, consider the following:

• No Power/No Response:
  • Check the main power supply to the controller (100-240Vac).
  • Verify all wiring connections are correct and secure, especially the input voltage.
• LED Strips Not Responding:
  • Ensure the receiver (sold separately) is correctly wired to the LED strips and has power.
  • Verify that the touch panel and receiver are successfully matched (refer to Section 6.1).
  • Check the DMX512 or RF wireless connections as per the wiring diagrams.
  • Confirm the LED strips themselves are functional.
• Inconsistent Control/Signal Issues:
  • Ensure the touch panel and receiver are not located near large metal objects that could interfere with the 2.4GHz RF signal.
  • Try clearing and re-matching the codes between the devices (refer to Section 6.4).

9. User Tips

• Verify Wiring: Always double-check all wiring connections before applying power to prevent damage to the controller or LED strips.
• Optimal RF Placement: For wireless setups, avoid placing the touch panel or receiver directly behind large metal structures to ensure the best signal strength.
