- Automatically detect the RS232 or RS485 and data way, so you can easily connect in either direction.
- Compact size, long range transmission, high speed.
- Compatible ETA/TIA RS-232C standard and RS-485 standard.
- Interface: DB9 connect for RS232, and RS485, including one extra DB9 to screw terminal board.
- Data speed 300~115-21BDS
- Working mode: Asynchronous half-duplex
- Transfer distance: 5 meters for RS-232 end, and 1200 meters for RS-485 end.
- Signal:
- RS-232: TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND
- RS-485: Data+, Data-, GND
Application:
- Convert signal from RS232 to RS485
- On the end for RS485, you can connect up to 32 RS485 devices, need mach resistor 120ohm 1/4w to prevent interference.
