The JERRAY Wireless DMX512 2.4G Transceiver PCB Modules are designed for wireless transmission of DMX512 protocol data, suitable for LED stage lighting control. These modules operate in the 2.4GHz ISM band, offering 126 channels with automatic frequency hopping for reliable performance and high anti-jamming capabilities. They are compact, making them ideal for integration into various lighting fixtures.
Each module functions as both a transmitter and a receiver, allowing flexible configuration within a DMX lighting system. Communication is established by setting identical ID codes on the transmitting and receiving units.

3.1 Ukuxhuma Amandla
Connect the module to a stable 5VDC power supply. Ensure correct polarity to prevent damage to the unit.
3.2 ID Code Setting
The modules use ID codes to establish communication. There are 7 available ID codes, each corresponding to a specific LED color combination:
- 1: RED
- 2: OKULUHLAZA
- 3: BOMVU + OKULUHLAZA = OKULUTHUTHUSI
- 4: OKUBLU
- 5: OKUBOMVU + OKULUBLU = OKUPULUMILE
- 6: GREEN + BLUE = CYAN
- 7: OKUBOMVU + OKULUHLAZA + OKULUHLAZA KAKHULU = OKUMHLOPHE
To set the ID code:
- Press the "key" button once to indicate the current ID setting.
- Press the "key" button again to cycle through the ID values. Each press will increment the ID value by one.
- Select the desired ID code. Both the transmitting and receiving modules must be set to the same ID code for communication.
- If multiple wireless networks are used in the same area, ensure each network uses a unique ID code to prevent interference.

4.1 Establishing Communication
- Power on both the DMX512 wireless transmitter board and the receiver board.
- Press the "key" button on both the transmitter and receiver to set them to the same ID value. Refer to Section 3.2 for ID code setting.
- The red LED on the transmitter will flash when it is transmitting DMX data and searching for an interference-free frequency section.
- The receiver will automatically adjust its communication frequency section. The green LED on the receiver will flash until it receives data with the correct, matching ID value.
- Once communication is successfully established, the green LED on the receiver will flash faster as DMX data transmission rate increases.
4.2 Isimo Sesikhombi Se-LED
- LED constant light up: Indicates no DMX signal input or no wireless communication established.
- I-flash ye-LED ebomvu: Indicates the module is transmitting DMX data.
- I-flash ye-LED eluhlaza: Indicates the module is receiving DMX data. A faster flash rate signifies a higher data transmission rate.
4.3 RF Frequency
The modules operate within the 2.400-2.525 GHz RF frequency range, utilizing a total of 126 channels. The system automatically searches for and selects the optimal channel to minimize interference.
5. Ukuxazulula izinkinga
- No Communication (LED constant light up):
- Verify that both transmitter and receiver modules are powered on.
- Ensure the DMX signal is correctly connected to the transmitter.
- Check that the ID codes on both the transmitter and receiver are identical.
- Izinkinga zokugxambukela:
- If using multiple wireless DMX systems in the same area, ensure each system uses a unique ID code.
- Minimize physical obstructions between the transmitter and receiver.
- Avoid placing modules near other 2.4GHz wireless devices (e.g., Wi-Fi routers, Bluetooth devices) if possible.
- Incorrect LED Indication:
- Review the ID code and LED color correlation table in Section 3.2 to confirm the expected color for the set ID.
