Figure 4 power supply and network port

2) RS485: use RS485 to connect 485B and 485A, where 485B represents the

negative line of 485 and 485A represents the positive line of 485; 485 with

load of 32. The longest communication distance is 1200 meters. Generally

RS485 line more than 300 meters when it is necessary to use the terminal

resistance, 485 terminal resistance is 120 ohms.

3) Network port: connect RJ45 interface network cable, support automatic

crossover.

4) Indicator lights: Power (PWR), Link (LNK) and Active (ACT) lights, which

respectively represent Power supply, connection indication and data

indication.

1) Link is Green when the cable is connected.

2) When a TCP connection is established (or in UDP mode), the Link is

blue (actually with a faint green light). Can be used to determine
