No.6 high-power LED dimming
This function of high power LED dimming control card. The number of optical channels: 6 channel. Every road using PWM constant current modulation way. 1 w high power LED for high frequency PWM basins. Communication (physical layer) : RS232 / RS485 baud rate: 9600 bits: eight stop bit: 1 Communication protocol (protocol layer) : the host sends commands to the machine. The machine will return data to the host after proper execution. For confirmation. Communication process has a timeout mechanism of overflow. Frame structure: consists of 16 bytes. In order to frame the first addressable + address + command + + check and structure parameters. Return frame structure: consists of 16 bytes. As the card frame first + address + to + + check and structure parameters. Addressing mode: fixed address (the address is 00 - FE)/broadcast address (address is FF) Mistake proofing mechanism: the checksum + timeout mechanism. Each data frame (send/return frame frame) with the checksum. Timeout time of 80 Ms. Is a data frame (16 bytes) must be within 80 ms after. If he didn't finish 16 bytes within 80 ms. Is automatically discarded has received data. 

Boot the default brightness: is the board to electricity. Each LED brightness. The PWM block data is stored in the board of internal EEPROM. No lose when power supply drop. LED current brightness: after power on the board. By the host sends a command to set the brightness. The PWM value is not stored in the EEPPROM Send frame with four commands. Set the PWM. Get PWM. Set the card address. Get the card address Shipping list: Card + 3 w light + 12 v power supply + serial port
