rayihni RS232 to RS485/RS422 converter

RS232 to RS485/RS422 serial converter can be used as an RS232 to RS485 or RS232 to RS422 converter, without the need for jumper switching. Network connection mode can be connected to the corresponding mode to work adaptively RS232 to RS485/RS422 serial port adapter is a passive interface converter with surge capability and can be connected to an external power source. RS232 is a passive port that can also work without relying on stealing power from signal lines. Ordinary interface converters are not equipped with high-energy protection devices, and the wiring board connects the GND terminal to the lightning protection ground RS232 to RS485/RS422 adapter is an adaptive interface with zero delay automatic transmission and reception conversion. I/O circuit automatically controls the direction of data flow and enables automatic switching of transmission/reception control Compatible with EIA/TIA RS-232C standard and RS-485/RS-422 standard; RS422 full duplex and RS458 half duplex working modes. Signal: RS232C: TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND-RS485/422: D+/A (TX+), D -/B (TX -) RX+、RX-、GND、+5V-+12V DB9 serial adapter are widely used in attendance machines, IC card charging systems, industrial automation control systems, one card access control systems, parking lot systems, self-service banking systems, bus charging systems, canteen meal systems, highway toll station systems, etc › See more product details
