The GM-1010-B interface converter converts data (TXD,RXD) of RS-232C to TTL/COMS; the TTL electrical level is 0-5V, without an external power supply. It adopts unique "RS-232 charge pump" technology to drive the system, and gains power without initializing RS-232 serial port, with internal zero delay auto transceiver and unique I/O circuit data flow direction automatic control, there is no need any handshake signals(such as RTS, DTR, etc), and this guarantees that there is no need to modify the programming under RS-232 full-duplex mode, it will runs smoothly and compatible with current software and hardware under TTL mode. The baud rate is 300-115.2Kbps.
