1) Serial port feature: Concurrently compatible with RS-232C, RS-485 standard of EIA/TIA

2) Electric interface: RS-232 interface is DB9 interface (female). RS-485 interface is DB9 interface (male), or RJ-45 interface. DB9 needle (male) interface can adapt to patch panel, and through binding post it is convenient to wire routing

3) Protection rate: 600W surge protection

4) Signal indication: Indicator lights TXD,RXD,POWER

5) Work methods: Asynchronous half-duplex differential transmission

6) Transmission media: Twisted pair or shielded cable

7) Transmission distance: 1,200M (115200bps~9600bps)

8) Work environment: -25C to 70°C, relative humidity: 5% to 95%

9) Power Input: DC 9V/350mA

10) Size: 63 x 33 x 17mm
