Power Center Configuration
ID Configuration
Connect the RS485 converter to the PC/laptop and connect the other ends of the wires to the Data Logger.
Open Power Center > Open the “Active Device” drop-down menu, and select the “Power Device”
Click on “Services Center” > “DataLogger USR-IOxx” > Set the “Communication Baudrate” to 9600 > Check the “ID Scan Mode” – to find the current ID default of the device.
Please note! If the current device ID is set according to your wiring diagram, then no additional action is needed, and move on to the next stage.
Click “Next”
In “Device ID” – set the ID device according to your wiring diagram, then click the “Set New Configuration” button.
Please note! Make sure that the “Communication Baudrate” stays on 9600.
10. Click “Yes” when a window will pop up.
12. Once the Power Center detects the device, values will appear in the “Reading Results” section.
