LITE SYSTEM INSTALLATION AND SUPERVISOR GUIDE 9.0 VER. 1

2. A screen displays, prompting you to indicate the type of connection you are establishing.

To indicate you are using a null modem cable connection, type N then press <Enter>.

3. The screen refreshes with a display that emulates the Lite system unit. The keyboard and

monitor of the laptop now effectively control the Lite system unit.

Note: If the screen displays a message indicating the program is shutting down

communications, you may need to adjust the COM port settings specified in

the KeyLink program. Do this by repeating step 1, then typing P to select

Port Assignments (instead of N) in step 2. Using, the up and down arrows,

select the COM port to which the null modem cable is installed, then press

<Enter>. Repeat steps 2 and 3.

If the appropriate COM port combination is specified, and you still cannot

establish communication with the Lite system unit, verify that you are using a

true null modem cable. Because it is difficult to visually distinguish null

modem cables from other serial cables, some users mistakenly use the

wrong cable type.

4. Follow the procedures in this document to set up the Lite system.

Note: If you type EDIT to invoke a DOS editor on the Lite system unit, you will

invoke a special editor pre-installed on the unit. This editor was developed

specifically for use with a null modem cable. (Traditional DOS editors

cannot communicate effectively over a null modem cable.)

5. To break the connection between the laptop and Lite system unit, press <Ctrl>-<Break>.

The KeyLink program ends its communication with the Lite system unit, and the laptop

screen refreshes. To re-establish communication with the Lite system, repeat step 1.

Note: For information on transferring files between the Lite system and the

attached PC, refer to section 10 of the Installation and Maintenance Manual

or contact Key Voice technical support.
