Setup Instructions
Follow these steps to correctly set up your CHINLY wireless DMX system:
- Connect the Transmitter: Plug the DMX wireless transmitter into the DMX output port of your lighting console or DMX controller. Ensure a secure connection.
- Connect the Receivers: Plug each DMX wireless receiver into the DMX input port of your DMX-compatible lighting fixtures (e.g., PAR lights, moving heads).
- Power Connection: Connect the provided power adapters to each transmitter and receiver unit, then plug them into a suitable AC100-240V power outlet.

Operating Instructions: Establishing Communication
To establish wireless DMX communication between the transmitter and receivers, follow these steps:
- Power On Receivers First: Ensure all DMX512 wireless receiver units are powered on before powering on the transmitter.
- Power On Transmitter: After all receivers are powered, power on the DMX wireless transmitter unit.
- Set ID Value: Press the "Key" button on both the transmitter and each receiver to set them to the same ID value. The units will display their current ID.
- Important: If you need to use multiple independent wireless DMX networks in the same location, ensure each network uses a different ID value to prevent interference.
- Observe LED Indicators:
- The red LED on the transmitter will flash when it is transmitting DMX data on an available frequency section.
- The receiver will automatically search for and change to the communicated frequency section.
- The green LED on the receiver will flash once it receives data with the matching ID value. The faster the green LED flashes, the more DMX data is being received.
- Communication Established: Once the green LED on the receiver is flashing, communication has been successfully established, and your lighting fixtures should respond to DMX signals from your console.

Troubleshooting
- No DMX Signal / Lights Not Responding:
- Ensure all units (transmitter and receivers) are powered on.
- Verify that the ID values on the transmitter and all receivers match. Press the "Key" button to cycle through IDs.
- Check DMX cable connections between the console and transmitter, and between receivers and fixtures.
- Confirm the DMX console is outputting a signal.
- Ensure the green LED on the receivers is flashing, indicating DMX data reception. If not, try re-pairing.
- Reduce the distance between the transmitter and receivers, or clear any obstructions.
- Intermittent Signal / Flickering Lights:
- Check for strong 2.4Ghz interference from other wireless devices (Wi-Fi, Bluetooth, other wireless DMX systems).
- If using multiple wireless DMX systems, ensure each system uses a unique ID group.
- Relocate units to minimize interference.
- Ensure units are within the specified 400M visible communication distance.
- Unit Not Powering On:
- Verify the power adapter is correctly connected and plugged into a live power outlet.
- Check the power adapter for damage.
Maintenance
To ensure the longevity and optimal performance of your CHINLY DMX Wireless System, consider the following maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the units. Do not use liquid cleaners or solvents.
- Storage: Store the units in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Handle the units with care to avoid physical damage, especially to the DMX connectors and antennas.
- Power Adapters: Regularly inspect power adapters for any signs of wear or damage. Replace if necessary.
