2. Choose the target recorder from the Select IED list in TESLA Control Pan-
el’s Main Menu.
• If there is not already an entry for this recorder, create one using the Add
New button.
• The method of communication with the recorder is specified as part of
its IED definition. Use the Edit button to view or change this informa-
tion. Ensure the Direct Serial Link option is selected.
• For details on IED definitions see “Working with TESLA Control Pan-
el” on page 5-1.
3. Initiate the connection by selecting the Connect button.
• A dialog box will appear to show connection progress.
• The connection state and the current IED you are connected to is shown
on the Windows status bar at the bottom of the screen.

If the connection fails, check the following:
• The communication parameters are the same on both ends (see Step 1
above).
• The correct serial port has been selected on your computer.
Some newer laptop computers do not have serial ports. A USB serial
converter adapter can provide a surrogate serial port for a direct
connection to the TESLA recorder. The Edgeport USB Serial
Adapter, model # Edgeport/1, from B&B Electronics
(www.bbelec.com) is an example of such a device.

software is connected to the recorder
and the name of the Current IED.
