A.2.2 Connect to the Service Terminal Interface

After creating and setting up a connection, use a communications program such as HyperTerminal to access the AC4’s Service Terminal Interface.

1.Verify communications connections between the remote computer and the AC4. Connect a null modem cable from the computer’s COM1 port to the AC4’s RS232 port (for location, see 3.4 - RS232 Connector).

2.Start the HyperTerminal program—click on the Start button, then on Programs, then Accessories, then Communications, and finally HyperTerminal.

3.Open the AC4 connection created in A.2.1 - Create a Connection. To do this, click on File, then on Open, as shown below.

Click on the file name - for example, AC4.ht

4.In the Open window, shown above right, select the file name—AC4.htin this example—and then click on the Open button.

5.Press Enter (or Escape) to initiate communication and bring up the Main Menu.

For more information on the AC4’s options:

See A.3 - Overview of Menus for examples of the Service Terminal Interface screens.
