Liebert AC4 用户手册

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.
