EA-01 RS232 to RS485 Serial Converter

  • Bidirectional converter interfaces RS-232 and RS-485 between applied between the master form between the host computer and the microcontroller or peripheral point to point, multipoint remote multi-machine communication network, multi answering machine communication, widely used in industrial automation control systems, card access control systems, parking systems, self-service banking system, bus fare collection system, canteen canteen system, employees attendance management systems, highway toll station systems, etc. .

Serial feature Interface compatible with EIA / TIA RS-232C, RS-485 standard 
Electrical Interface RS-232C terminal DB9 female connector port, RS-485 terminal DBP pin connector port with terminals (four or six wiring wiring) 
Way of working Asynchronous half-duplex
Transmission medium  Ordinary line, twisted pair or shielded cable
Transmission rate  300-115200BPS 
Transmission distance 5 m (RS-232 terminal) 1200 m (RS-485 terminal) 
letter of agreement  Transparent 
signal  RS-232: TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND RS-485: Date +, Date-, GND 
working environment  -10 ℃ ~ 85 ℃ 
Operating temperature 5% to 95%
Power supply Efficient serial stealing technology, no external power supply, real three line (TD, RD, GND) communication system

The converter can convert RS-232 serial port TXD and RXD signal into balance half-duplex two-wire RS-485 signals. No external
power supply, directly from 3 feet RS-232 port stealing, while the 7 feet Request to Send (RTS), 4 pin Data Terminal Ready (DTR)
to the auxiliary power supply converters, automatic flow control so you do not have to re set of hardware and installation is very simple.
Applications:Point-to-multipoint communications;Industrial distribution system, industrial control automation;Road traffic control automation;
Closed-circuit monitoring;security system;Smart cards, attendance access control systems.




Wire half duplex, efficient stealing, no external power supply, support remote 1.2km, 128 nodes, serial protection, hot-swappable,
with only RX and TX, speeds up to 115.2k, industrial design, anti-lightning, anti-static, widely used in industrial automation control
systems, card access control systems, parking systems, automated banking systems, vehicle charging system, employees attendance
management system, highway toll systems.
