UST232485A is one multi-function RS-232/RS-422/RS-485 Converter, concurrently with RS-232/RS-422/RS-485 standard, which can convert RS232 signal of single end into RS422 or RS485 signal of balanced difference. RS232 interface connects with computer serial port through D89 female din. RS422/RS485 connects 6-digit connecting end through D89 pinhead or connects directly by RJ45 interface and equipment RJ45 interface. RS485 supports double line half duplex, which means data should be sent or received through only 2 lines of RS485. Handshaking signal usually control the direction in which data is sent. And the circuit inside HXSP-2108B interface converter may apperceive data flow direction and switch enable-control automatically. A RS-485 network can be formed conveniently without any handshaking signals, and the RS485 enable-control is completed transparent, which means, there is no need to modify any software for the past operation methods based on RS-232. This product is of small dimension, long-distance transmission, high efficiency, stable performance, etc. RS-232/RS-422/RS-485 is applied inside the interface without switch and is widely used in personal attendance management system, one card universal gate inhibition system, park system, automatic bank system, bus charging system, restaurant sale system, and highway toll station system, etc. Features
