In order to facilitate data communication between external devices or intelligent instruments equipped with different standard serial interfaces, it is necessary to convert the standard serial interfaces. UT-210T interface converter can convert the RS-232C serial interface data transmission (TXD) and data reception (RXD) signals into TTL/COMS compatible level, and the converted TTL level is 0-3.3V, No external power supply is required. Driven by a unique "RS-232 charge pump", power can be obtained without initializing the RS-232 serial port. It has zero-delay automatic sending and receiving conversion inside, and the unique I/O circuit automatically controls the data flow direction. Without any handshaking signals (such as RTS, DTR, etc.), it ensures that programs written in RS-232 in full-duplex mode can run in TTL mode without modification, ensuring that it is suitable for existing operating software and interface hardware. Converter transmission rate 300-115.2Kbps.
