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 Liebert 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.
