take note of

RS485 lead wire are A (data +) and B (data -), and equipment RS485 connection A (+) connected to the A (+), B (-) connected to the B (-), interference in the case of serious recommended to connect the GND together.

This product can be used with 32 terminal 485 devices, with a maximum communication distance of 1200 meters. The maximum communication distance is 1200 m. The 485 termination resistor is 120 ohms, which is usually necessary for wiring over 300 meters. Note that when wiring, A+ and B- must be a pair of twisted pairs hinged together to minimize signal interference.
