This converter is compatible with RS-232C and RS-485 standards. It converts single-ended PS-232 signals into balanced RS-485 differential signals and extends the communication distance to 1.2 km. The converter is passive and does not require an external power supply. It uses a special current pump technology to draw power from RS-232 signals (RTS, DTR, TXD) without prior initialization of the RS-232 interface. Internal transceivers and special circuits automatically control the direction of the data stream without the need for handshake signals (such as RTS, DTR). If the software works in RS-232 half-duplex mode, it can maintain the same function in RS-485 mode without modification. The baud rate of 300-115200 bps can be applied to communication between the master computers, the master computer and external devices, and can form a point-to-point, point-to-multipoint communication network. It is widely used in industrial automation, access control, card, parking lot, ATM, bus charging, canteen sales system, employee attendance management, highway toll stations and other occasions. Size: 57mm*37mm*17mmbr> Working environment: 2-50 ° C, relative humidity 5%-95% (commercial working environment is 0-70 ° C), (industrial working environment is -20-85 ° C) Communication distance: 1200 meters (RS-485 end), 5 meters (RS-232 end)

Communication rate: 300-115200bps. Transmission medium; twisted pair or shielded twisted pair. Working mode: asynchronous, half duplex. Differential transmission. Electrical interface: rs-232 end is a DB9 female (hole shape), RS-485 end is a 4-digit terminal. Interface: Compatible with EIA/TIA RS-232C standard and RS-485 standard.
