3onedata | SW485C | Industrial-grade RS-232 to RS-485/422 Converter
The SW485C is an industrial-grade interface converter that facilitates bidirectional data conversion between RS-232 and RS-485/422 serial ports without requiring an external power supply. It features a compact design, long transmission distance, high speed, and stable performance, making it suitable for use in electric power systems, industrial automation control, and IC card charging systems. The device is equipped with 600W surge protection and 15kV electrostatic protection to prevent damage.
Specifications
- Serial Port: Supports EIA RS-232C, RS-485, RS-422 standards with one RS-232 and one RS-485/422 port. The RS-485 and RS-422 modes can be switched via a jumper.
- Signals: RS-232 uses TXD, RXD, GND; RS-485 uses D+, D-, GND; RS-422 uses T+, T-, R+, R-, GND.
- Baud Rate: 0~115200bps.
- Interface Type: RS-232 uses a DB9 female connector; RS-485/422 uses a 5-pin terminal block.
- Transmission Distance: RS-232 up to 15m; RS-485/422 up to 1200m.
- Direction Control: Automatic data flow control for RS-485.
- Load Capacity: Supports 32-point polling, customizable to 128 points.
- Protection: 600W surge and 15kV electrostatic protection.
