Wire the Polar Gateway to a 12-24 V DC power supply. Connect the positive wire to the positive terminal and the negative wire to the negative terminal.

2. Connect RS-485

Wire the RS-485 cable to allow communication with the Polar Gateway. Connect A+ => A and the B- => B.

3. Final checks
Before you switch on the Gateway and the device make sure you have done everything correctly in the previous steps.
 
  • Make sure the wiring is secure – no short circuits.
  • Check if the power cables are not loosely wired to the Gateway.
  • Check if the power cables are not loosely wired to the device.
