Overview
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-422 standards. It converts RS-232 signals into balanced
differential RS-422 signals. The transmission distance of RS-232 communication
can be extended to 1.2km. 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 (RTS, DTR); this guarantees that there is no need to modify
the programming under RS-232 full duplex mode, it will run smoothly under RS-322
mode, ensure to suitable for current software and hardware. The transmission
rate is 300-115.2kbps. 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.
