RS-232 to RS-485/422 Converter Adapter Port-Powered Industrial RS232 to RS422...
Serial converter adapter converts TXD and RXD signals from a single ended RS232 serial port into balanced differential RS485 or RS422 signals without the need for an external power supply;
Widely used in industrial automation control systems, one card systems, access control systems, parking systems, self-service banking systems, bus fare systems, company employee attendance management systems, etc.
Supports the following four communication modes:
1. Point to point/four cable asynchronous full duplex (RS-422 mode);
2. Point to multipoint/four cable asynchronous full duplex (RS-422 mode);
3. Point to point/dual cable asynchronous half duplex (RS-485 mode);
4. Point to multipoint/dual cable asynchronous half duplex (RS-485 mode).

Packaging includes: 1PC * RS232 to RS485/422 serial converter
- RS232 to RS485/RS422 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 converter 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 interface 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 -) converters 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
