RS-232 to TTL Converter (Industrial Standard)

From the shop's description

RS-232 to TTL converter (UT-210) converts data (TXD, RXD) of RS-232 to TTL signal. The TTL electrical level is 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. The RS-232 to TTL converter has an automatic transmission and reception conversion with no delay. It has a unique I/O circuit auto control data flow direction. With these, you don't need any handshake signal (RTS, DTR). The RS-232 converter run smoothly and is compatible with current software and hardware without modifying the software. Specifications Standards: RS-232 TIA/EIA, TTL Power: port-powered over RS-232, no need external connected TXD/RXD/GND communication Baudrate: 300bps-115.2Kbps Works with all communication software, plug & play Supports all operating system Dimension: 62×34×18mm Operating temperature: -40℃ to 85℃ Industrial RS-232 to TTL converter (UT-210) datasheet Industrial RS-232 to TTL converter (UT-210) manual
