Description: Parameter: Product Name: USB to TTL download line Length: 1 meter Chip: PL2303HX, PL2303TA, Line order definition (Red +5V,Black GND,Green TXD,White RXD) Description: Please do not directly get the operation, first do a simple test, the method is very simple: If you plug the line into the computer, the computer prompts "find new hardware....", connect with a black pen (GND) The red pen can be connected to both (RX) and (TX) to measure the voltage, which means the small board must be good. Here, it is specially stated that if (GND) is connected to the voltage pin of the device, the power-on must be burned, so the pin of the device must be accurately measured before wiring. Pin connection and description: Please be sure to find the pin definition before connecting, especially the GND must not be connected to the voltage pin, and the RX and TX terminals should not be connected to the VCC pin. (The actual VCC pin voltage is up to 14V.) Will burn the patch chip, Connection method: only 3 wires are needed for the brushing machine. Generally, only three signal lines of RX TX GND are used, and VCC is not connected. Above is a 4, 5 pin friend, do not need to connect VCC and BT pin. When using, please connect RXD with target board TX, TXD is connected with target board RX, GND is connected to GND, if not, adjust RX and TX. Connection method: RX to TX; TX to RX; Ground to ground (GND to GND) Red VCC Black GND White RXD Green TXD USB to serial port small board function: 1 Simple serial communication. 2 router or ADSL firmware upgrade. 3 GPS serial communication. 4 Hard disk firmware upgrade. 5 Easy to use, RX is connected to the TX of the MCU; TX is connected to the RX of the MCU. There is no need to convert with MAX232. 6 used in the HyperTerminal; commonly used serial debugging tools. 7 Various satellite machines are upgraded. ect...............Universal USB to serial portlet
