12.Verify that you have a connection between the computer and the Protocol Adapter. Have the Protocol Adapter within eyesight of the computer keyboard. Type any character and confirm that the “RS-485, Data, TX” LED and the “RS-232, Data, RX” LED (see DIAGRAM 6 on page 10) on the Protocol Adapter flash as you type. The LEDs flash very quickly.

13.Press Enter to clear the command line.

Note: On Windows ’98 computers, HyperTerminal does not echo typed characters (doesn’t show them on the screen as you type) locally. Do not be concerned. This can be a little confusing, but does not affect the checkout of the thermostat communication system.

•If you were unable to verify a connection, specify a different com port. Go to the File pull down menu, and select Properties. Change the “Connect using:” setting to a different port by using the pull down menu options. Start typing and look for the Protocol Adapter LEDs to flash. Repeat until you have successfully verified connection between the computer and communication system, or until you run out of com ports to choose from in the “Connect using:” pull down. If there is still no communication you are going to have to consult a computer professional.
