To carry out the digital communication between external devices or intelligent instruments with different standard serial interfaces, standardize the serial conversion is necessary. Rs 232 to TTL converter(UT-210) converts data (TXD, RXD) of RS-232C to TTL/COM; the TTL electrical level is 0-5V, without external power supply. It adopts unique "RS-232 charge pump" technology to drive the system and gains power without initializing the RS-232 serial port.
As rs232 to TTL adapter, this converter has an automatic transmission and reception conversion within no delay, and a unique I/O circuit auto control data flow direction. With these, we don't need any handshake signal (RTS, DTR). And rs 232c converter can run smoothly and is compatible with current software and hardware under TTL mode, without modifying the programming under RS-232 full-duplex mode. The baud rate is 300-115.2Kbps.
