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.
4. In the Open window, shown above right, select the file name—AC4.ht in 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.
