Using the Modem Port

The internal modem of the INF+M card is an asynchronous, ITU-T V.22bis modem. It allows

remote access to the terminal interface and automatic reporting of alarm messages to a remote

device. Table C-7 lists the specifications of the modem.

Table C-7. Modem Specifications

Connect the MODEM jack to a phone line, using a modular telephone cord. This is an RJ-11

jack; it uses only pins 3 (Tip) and 4 (Ring). Figure C-9 shows the jack pin orientation.

Figure C-9. MODEM Jack

The modem automatically answers incoming calls. A remote operator can press the <Enter>

key to display the log-in screen. After entering a valid password, that operator has complete

access to the user interface.

To disconnect, the remote operator logs off and then hangs up. The modem automatically

resets and waits for the next call.
