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

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 twisted pair (STP)

7) Transmission distance: 1,200M 5m(RS-232)

8) Work environment: -20C to 85°C, relative humidity: 5% to 95%

9) Mechanical dimension: 95x33x17mm
