Step 4 - RS-485 to USB converter

You must have an RS-485 to USB converter.

The download file is available at the bottom of the page.

Process 3 - Establishing serial communication

Step 1 - Making the physical communication connection

Connect terminals 15(-) and 16(+) on the RS-485 > Serial converter connected to the computer.

Step 2 - Check the connection and communication port

Open Windows device manager:

Check the port corresponding to the converter. 

Process 4 - Configuring the communication

Step 1 - Define time out and number of retries.

The Time Out is the maximum value of time that the software will wait for a response in communication with the equipment. This value must be entered considering the time in milliseconds.

The field Attempts refers to the maximum number of times the system will try to establish communication with the IDM. When the time-out time is exceeded in all X attempts, the software will accuse of communication failure.

Step 2 - Verify settings on the IED

Press and hold the P key for 5 seconds until you reach the following screen:

Use the ↑ and ↓ keys to enter the password to access the parameterization menu, then press ↵ to enter the menu. (For initial value = 4210, the default password is "0").

Navigate to the "CONF" menu and press the ↵ key.

Change between the settings using the ↵ key, check and note the address and BaudRate values.

Step 3 - Putting information into the software

• Select BaudRate according to the BDR value on the IED;
• Insert COM port as the value seen in step 2 of process 3;
• Insert address as the END value in the IED;
• Then click the Connect button.

Process 5 - Selecting Memory Range and Exporting Data.

Step 1 - Choose between the memory range options that you want to export:
