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).
