This guide will show you how to connect the Polar Monitoring Gateway to the Soccomec DIRIS A20/30/41 electricity meter. It will also take you through the setup and parameters required on the Soccomec DIRIS A20/30/41 to ensure communications to the Polar Gateway.

Steps to follow:

Connect power to the Gateway.
Connect RS-485.
Final checks.
Power on the system.
Configure the DIRIS A40 Serial Parameters

Soccomec DIRIS A20/30/41 Connection Setup

1. Connect power to the Gateway

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+ => + and 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.
Re-check the RS-485 twisted pair cable is correctly wired.

4. Power on the system

Now you are ready to go, you can now switch on the Polar Gateway and the DIRIS A10.

5. Configure DIRIS A20/30/41 Serial Parameters

In order for the Gateway to correctly communicate with the Soccomec DIRIS A20/30/41 controller, there will need to be some changes made to the communication parameters.

Note: It is critical to change the default settings to reflect the table below.

Serial Communication Setup

Name	Description	Parameter	Default	Required
Communication Address	Serial Node Address	Addr	5	1
Serial Speed	Baud Rate	bAu	38.4k	9600
Parity	Communication Parity	Prty	n=no	N=no
Stop bits	Communication Stop Bits	StoP	1	1

You may now sign in to the Polar Portal to monitor the device remotely, the button on the right will take you through a setup process.
