4. Setup & Installation
4.1 Power Connection
Connect the provided DC 5V power adapter to the "POWER" input on the DMX Splitter. Ensure you use the correct adapter type for your region (US, EU, UK, AU).
4.2 DMX Signal Connection
- Connect your DMX controller's output to the "DMX IN" port on the splitter using a 3-pin XLR cable.
- Connect your DMX-controlled lighting fixtures (dimmers, par lights, moving lights, etc.) to the "DMXOUT 1" through "DMXOUT 8" ports using 3-pin XLR cables.
- If you need to daisy-chain the DMX signal to another DMX device or splitter, use the "DMXOUT" (direct output) port.
4.3 Mounting
The DMX Splitter features a hook mounting design, allowing it to be hung on a wall or other suitable surfaces. Please note that hanging hooks and nails are not provided with the unit.
5. Operating Instructions
5.1 Powering On/Off
After connecting the power adapter, press the red "POWER" switch to turn the unit on. The red Power LED will illuminate. To turn off, press the switch again.
5.2 DMX Signal Indication
The green "Signal" LEDs will illuminate when a DMX signal is detected on the corresponding output channel, indicating active data transmission.
5.3 DMX512 Wireless Receiver Function (Wireless Version Only)
For models equipped with a wireless receiver, follow these steps to set up wireless DMX communication:
- ID Code and LED Color Relationship: The wireless system uses 7 groups of ID codes, each corresponding to an LED color combination:
- 1: RED
- 2: GREEN
- 3: RED + GREEN
- 4: BLUE
- 5: RED + BLUE
- 6: GREEN + BLUE
- 7: RED + GREEN + BLUE
- Setting the ID:
Press the "KEY" button (located near the FR ID indicator) to cycle through the ID codes. Each press will advance the color ID code by one. Set the desired ID code to match your wireless DMX transmitter.
- Working Condition:
- LED constantly lit up: Indicates no DMX signal or no wireless signal.
- Green LED flash: Indicates the unit is receiving a wireless DMX signal.
The wireless receiver will only operate when its ID code (1-7) matches the ID code of the DMX transmitter. Ensure both devices are set to the same ID color for proper communication.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use abrasive cleaners or solvents.
- Storage: Store the DMX Splitter in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Inspection: Periodically check all cables and connections for any signs of wear or damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power LED indication | No power supply or faulty adapter/cable. | Check power connection, ensure adapter is plugged in, and verify power outlet. Try a different power adapter if available. |
| No Signal LEDs illuminated | No DMX input signal or faulty DMX cable. | Ensure DMX controller is sending a signal. Check DMX IN cable connection. Test with a known working DMX cable. |
| Intermittent DMX signal | Loose connections, signal interference, or faulty DMX cable. | Secure all DMX cable connections. Ensure cables are not too long or running near power lines. Replace suspect DMX cables. |
| Wireless DMX not working (Wireless Version) | Incorrect ID code, out of range, or interference. | Verify the ID code on the splitter matches the transmitter. Ensure the splitter is within the 300m visible distance range. Check for other wireless devices causing interference. |
8. User Tips
- For optimal signal integrity, use high-quality DMX cables.
- When using the wireless version, ensure a clear line of sight between the transmitter and receiver for the best performance.
- Consider using DMX terminators on the last device in a DMX chain to prevent signal reflection issues.
