RS232 to RS422 Data Interface Adapter Converter
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. Converter compatible with RS-232C, RS-485, RS-422 standard, single-ended to the RS-232 balanced differential signal is converted to the RS-485 or RS-422 signals.
Converters can be RS-232 communications to extend to 1.2 kilometers away from the need for external power supply using a unique "RS-232 charge-pump" driven by the initialization does not require RS-232 serial port available power.
Internal transceiver with auto-zero time delay conversion, unique I / O circuit of automatic control data flow direction, and without any handshake signal (such as RTS, DTR, etc.), no jumper settings to achieve full-duplex (RS-422) , half-duplex (RS-485) model of conversion, so as to ensure the RS-232 full duplex, half-duplex mode without changing the preparation procedures can be run in RS-485/422 mode to ensure that it meets the existing operating software and interface hardware.
Transfer rate converter 300-115.2Kbps, can be applied to Master Control between Master Control between peripherals and MCU or constitute a point-to-point, point-to-multipoint communication network remote multi-response multi-machine communication widely used in industrial automation control systems, card, access control systems, parking systems, self-service banking system, the bus fare collection system, canteen ticketing system, the company staff attendance management systems, highway toll station systems.
