תיאור
-
- This converter is compatible with RS-232C,RS-485,RS-422 standard ,enable transfer RS232 Signals to Balance Difference RS485 or RS422 signal.
-
- Converter can extends RS232's transmission distance to 1.2KM, drive by using special RS232 charge pump without external power, get power withoutinitialized RS
-
- 232.Inside,there is zero-delay auto transfer, and unique I/O circuit automatically controlling Data flow direction without any hand-shake signals(e.g.:RTS,DTR,etc).
-
- The exchange of Full-duplex (RS-422) and Half-Duplex modes can be realised without jumper,so it ensure the programm under the way of RS232 full-duplex and half-duplex to
-
- run without any modification, so to ensure it compatible with current operation software and interface hardware, and transmission speed as 300-115.2Kbps.
-
- It can be used between main controllers,between main controller and panel machine or external equipment to creat point-to point,point-to-multipoint remote multi-machine
