One-stop solution for all your connection needs In order to facilitate the allocation of a different standard computer serial interface, external devices or between the intelligence apparatus for remote data communication, the need for standards conversion of the serial interface. Convert an RS232 data signal to RS485 or RS422 The DTECH Industrial RS232 to RS-422/485 Serial Converter is a bi-directional adapter that lets you adapt an RS232 data signal to either RS485 (2 or 4-wire) or RS422 and vice-versa, with support for baud rates up to 115.2 Kbps. The adapter supports auto baud rate detection as well as RS-422 and RS485 mode detection, and supports connection distances of up to 4000ft (1200m). It is suitable for most applications, including industrial, commercial and any general office computer device. Specific Compatible with RS232C,RS485,RS422 TIA/EIA standard Baud rate: 300bps to 115.2Kbps Automatic send / receive data, without external flow control signals. Zero delay automatic transmission Supports multiple terminals up to 32 RS-485 or RS-422 devices Transmission distance: up to 4000 Feet (1200 meters) for RS-485/422 end Power supply: Unique serial charge pump drive technology, no external power supply. Working modes: Asynchronous half-duplex(RS485) or asynchronous full duplex(RS422),no need jumper wire settings. Transmission media of RS232 Data Converter: twisted pair or shielded twisted pair ( STP ).
