User manual

Specification for Product Selector V1.2 1. USB connector or 4pin 2.0 connector: connect to Media Player or other unit to communicate with each other, also can get the power from this connector(Just Host Device, and the protocol please see point 9) 2. Pairing Key and Pairing Indicator: Pairing Key is used to pair the host device and slave device, right now one host device can pair with up to 32 pcs slave devices with ID from 1 to 32. Pairing Indicator can indicate if the device is working on pairing mode and success for pairing Pairing: 2.1. Set the host mode and slave mode on the device according to the below information(Point 6) 2.2. Press and hold th e Pairing Key, and then power on, after 5 seconds, the Pairing Indicator will flash to indicate the device are working in pairing mode 2.3. Setting the slav e device to pairing mode one by one and then setting the host device to pairing mode. 2.4. After pairing succe ss, the Pairing Indicator will be on 2.5. After all the de vice pairing success, power off the devices or wait 20seconds for auto reset. 3. Reset Key: Reset the system 4. Mode and ID setting switch: Host/Slave mode setting: There are two resistors for Host or Slave mode setting. Shown as the pictures below: When R41 is connected, the device is working on Host Mode;
and when R49 is connected, the device is working in Slave mode. When in host mode, there is a pin setting to set the bit rate to 9600bps or 19200bps. We used ID1 for this setting. When ID1 is short, the bit rate is set to 19200bps, and when ID1 is open, the bit rate is set to 9600bps. When in host mode, there is 3 pin setting (ID4, 5, 6) to set the quantity of slave device. When ID4 is short, the host support to 8 pcs slave device; and when ID5 is short, the host device support to 16 pcs slave device; when ID4 & 5 are short, the host device support to 24 pcs slave device; and when ID6 is short, the host device support to 32 pcs salve device. When device is working in Slave mode, the 8x3 jumper connector is used for ID setting. As the picture below showed: In the new device, we have change the ID setting mode. The ID setting was divided to single digit and tens digit. 1-5 and 12-16, total 10 pins have changed to the single digit (1-1, 2-2, 3-3, 4-4, 5-5, 12-6, 13-7, 14-8,15-9, 16-10, none-0); and 6-8, total 3pins have changed to tens digit (6-10, 7-20, 8-30). When set the slave ID, we need to short the single digit and/or tens digit. Such as if we set the slave ID as ID9, then we need short the current pin 15. If we set the salve ID as ID10, then we need short the pin 16 (or short pin 6). If we set the salve ID as ID20,then we need short the pin 7 (or short pin 6 and pin 16); If we set the slave
ID as ID32, then we need short the pin 8 and pin 2. 5. Push Button switch for output: this switch is just used on the slave device, for a switch signal which can trigger other device as our Media players, Audio box and etc. 6. LED Indicator for Slave device: When the module is setting for slave, this LEDs indicator will be off in standby, if Slave device N receive a command from the Host device, LED Indicator N will be on for 1second and PB switch for output will trigger as a push button function. 7. The host device can communicate with other device through UART protocol: UART Protocol V3.2（Add descriptions for the command） Interface UART 9600bps 8N1 Command Length: Number of bytes follow by Header Command: Packet Command Data: Packet Data Checksum: Checksum=Header+Command Length+Command+Data Command Trigger Command Active Slave Command (0x01) Usage: Send this command to trigger related slave active ouput, and Dongle will return battery level Command: 0x01 Data: Slave ID (0-15) Return: Related Slave Battery Level (0-2). 0=battery low, 1=battery good, 2=battery full Example: send: 0xf5,0x04,0x01,0x00,0xFA return: 0xf5,0x04,0x01,0x02,0xFC Get Active Slave Command (0x02) Usage: Get active wireless slave Command: 0x02 Return: 32bits to indicate 32slave status Example: send: 0xf5,0x04,0x02,0x00,0xFB
