UTEK UT-204E RS232 to RS485 Serial Adapter with 600w Surging Protection Industrial Grade Automation Data Transmission 1.2KM

UTEK UT-204E RS232 to RS485 Serial Adapter with 600w Surging Protection Industrial Grade Automation Data Transmission 1.2KM For communication between PC with different standard serial port and external equipments or intelligent instruments, standard serial conversion is necessary. This converter is compatible with RS-232C, RS-485 standards. It converts RS-232 signals into balanced differential RS-485 signals. This converter is designed to protect RS-485 port; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR). The transmission distance of RS-232 communication can be extended to 1.2 km. It adopts unique RS-232 charge pump technology to drive the system, and gains power without initializing RS-232 serial port.

This converter is with built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTU, DTR); this guarantees that there is no need to modify the programming under RS-232, it will run smoothly under current software and hardware. The transmission rate is 300- 115.2 kbps. It can be used between hosts, host and SCM, which building a point to point, point to multipoint long-distance communication networking. It is widely applied in industrial automation control system, all-in-one card, access control system, parking system, ATM system, bus charging system, canteen ticketing system, attendance system, and toll station system, etc.
