TLC422 is the interface converter between RS-232 and RS-422. It is powered from serial port (such as COM port of computer ), no outside power needed. Small size, long transmission distance, high rate, stable performance. It applys DB9 common serial port. It is used widely in the field of electricity, industrial automatic control, IC card billing system. It is a high quality low price data interface conversion product.
Features
1. Plug and play, small volume, easy installation
2. Convert RS-232 data transmit (TXD) and data receive (RXD) signal into full-duplex RS-422 signals. 3. Powered from RS-232 handshake lines -no power supply needed!
4. Point to multiple point
5. Automatic Send Data Control - no software drivers needed!
