Verification of IR Communications Port (Fluke 53 and 54)

This section explains how to verify the operation of the IR Communications Port (IR port). Perform the following procedure using a PC and HyperTerminal. The IR port can also be verified using Flukeview™ software.

To set up a HyperTerminal file, follow these steps:

1.Connect the IR adapter cable to the DB9 Adapter connector. Connect the other end of the DB9 Adapter to a COM port of the PC.

2.Place the Fluke 53 or 54 in front of the IR adapter.

3.Open up a HyperTerminal session. Select Start button, Programs, Accessories,

HyperTerminal.

4.Open up a New Connection with a name like “Fluke 54 IR Test”.

5.When the Connect To box appears, select the COM1 or COM2 (the port that the IR adapter cable is plugged into).

6.Select Port Settings: 9600 baud rate, 8 data bits, no parity, 1 stop bit, and no flow control.

7.Under File, select properties. Verify that the correct port is selected. Click on Configure. Verify that port settings are correct (the baud rate may need to be changed to 9600).

8.Select the Settings tab then click on ASCII Setup. Check the following boxes:

∙Echo typed characters locally

∙Append line feeds to incoming line ends

∙Wrap lines that exceed terminal width

To open a HyperTerminal file to test the IR port, use the following procedure:

1.Under File, select Save As. Use a file name such as “Fluke 54 IR Test” and then click on save.

2.Click on the phone disconnect icon.

3.Click on open folder or under File select Open. Double click on Fluke 54 IR Test.

4.Type in "ID" followed by the Enter key (notice the "ID" is capitalized).

5.The display of the thermometer now shows the thermometer name (Fluke 53-II or Fluke 54-II), and the units operating software version (e.g. Fluke 54-II, V1.01).
