Using an External Modem with your LINK AVS-816

This document outlines the basic steps required to connect and control an AVS-816 with an external modem. These instructions assume that the modem is compatible with the Hayes "AT" command set.

First of all, it will be necessary to edit the modem's configuration or "profile". This is done using a personal computer (PC) running a simple terminal program such as Procomm, Comit, or Windows(tm) Terminal. To read your modem's profile, simply issue the command:

AT&V

The resulting display will look something like this:

OK

You should modify the modem's profile by issuing the following commands:

ATS0=1 Select Auto-answer
AT&D0
AT&Q0 Instructs the modem to ignore the DTR line (not asserted by the AVS-816).
ATQ1 Turns off the modem's "result codes" (incompatible with the AVS-816).

Next, save these modifications in the modem's non-volatile memory by issuing the command:

AT&W0

Now, you are ready to disconnect the modem from the computer and connect it to the AVS-816. You will notice that both the AVS-816 and your external modem have female subminiature D connectors. Therefore, a special cable or adapter will be necessary with the following pin configuration:

Modem (25-pin) Modem (9-pin)   AVS-816 (9-pin)
3 2 ..connect to.. 3
2 3 ..connect to.. 2
7 5 ..connect to.. 5

All AVS-816s are shipped with a Windows(tm)-based remote control program with built-in modem dialer. For more information, visit the AVS-816 page on this website.
