Connecting to the Service Terminal Interface

A.2 CONNECTING TO THE SERVICE TERMINAL INTERFACE

This section describes how to set up and connect to the Service Terminal Interface. To access the Ser- vice Terminal Interface, you will need:

•A null modem cable to connect a computer’s COM1 port to the AC4’s RS232 port.

•A communications program, such as HyperTerminal, to connect to the Service Terminal Interface.

Refer to following sections for step-by-step instructions to set up a connection (one time) and use that connection to access the Service Terminal Interface:

•A.2.1 - Create a Connection

•A.2.2 - Connect to the Service Terminal Interface

The instructions in this section refer to the HyperTerminal program—they may vary for other com- munications programs.
