Press momentary switch the side led indicator to indicate ID setting. 2). Press again to set IC, to the color ID desired, adding 1 each time you press the switch will advance the color IDcode. 3). Working condition: LED constant lit up: No DMX or wireless signal. Red LED flash: Transmitting. Green LED flash: Receiving 4) RF frequency 2.400 - 2.525G, total 126 channels, it’s searching automatically. 5). ID Code “1-7” groups ID code, press ‘KEY’ for setting, it only can work under same ID code of transmitter and receiver. ( Same LED Color ) Establishing Communication 1. Power on DMX512 wireless received board first and then following to power up the transmitted board. 2. Press “Key” button to set same ID value of transmitted board and received board. Please use different ID value if you need use more than 1 group wireless universals at same time in same place. 3. The red LED flashes when transmitter transmits DMX data by no interfered frequency section, then receiver changes communicated frequency section. Green LED flashes until received same ID value, the more DMX data, the faster the LED flashes. 4. Communication was established correctly.
