A.2 CONNECTING TO THE SERVICE TERMINAL INTERFACE

This section describes how to set up and connect to the Service Terminal Interface.

A.2.1 Connection Methods

There are two ways to access the Service Terminal Interface:

•Direct—Use a null modem cable to connect a computer’s COM1 port to the AC8’s RS232 port,

OR

•Remote—Use a remote computer’s modem to dial the telephone number of the phone line con- nected to the AC8.

Both methods require a communications program, such as HyperTerminal, to connect to the Service Terminal Interface.

Refer to Table 34 for step-by-step instructions to set up each type of connection. Note that the remote connection does not require setting up the COM1 port.
