If you are not familiar enough with computers to follow the procedure steps below, you should find or engage the services of someone who has familiarity with Windows-based computers.

First, download the commands zip file. Next, unzip the file to a known location

• To determine which commands you need, see Identifying Data Formats and Operating Modes.

Next, start Hyper Terminal.

• Click Start, All Programs, Accessories, Communications, Hyper Terminal.
• In the "New Connection" dialog box, type Elo or a name of your choice in the Name box and click OK.
  • If you previously named and saved a Hyper Terminal session, click Cancel, then File, Open (or the folder icon) and double-click the session name. In this case, no further setup will be needed as all the correct settings will have been saved, so skip the next two bullets.
• Next, select the COM port from the "Connect using" drop-down at the bottom of the Connect To window, then OK.
• Select 9600 from the bits per second drop-down in the Port Settings window, then OK.
• The Hyper Terminal window opens.
• Click Transfer in the top menu, then select Send Text File (NOTE: "send TEXT file", not "send file").
• Use the Look In drop-down to navigate to the location of the previously saved command text files, then double-click the command file to send.
• A short character string should appear at the top of the window; it will be cryptic and meaningless, but will indicate a response from the controller.
  • If no characters appear, then no command was sent – check the setup, the connection and the controller status.
• Additional commands may be sent by selecting Send Text File from the Transfer menu (it may be necessary to restart Hyper Terminal for each command), then double-clicking the command file to send.
• Be sure to send the Save command last, to save the new settings in the controller.
• NOTE: If the Save command is not sent, all changes will be lost when power is removed from the controller.

See Identifying Data Formats and Operating Modes to check the data format.
