Section 19. REMOTE PROGRAMMING AND

CONTROL (DOWNLOADING)

General Information

The VISTA-20HWSE can be remotely programmed from an IBM compatible

Personal Computer (PC), a HAYES Modem, and Ademco's V-LINK® Software

(as specified below).

Downloading may only be performed if a technician is at the site.

Programming the control from a remote location is protected against compromise

by someone attempting to defeat the system, using multi-levels of security

protection:

1. Security Code Handshake: An 8-digit download ID code must be matched

between the control and the downloader .

2. Site Initiated Remote Programming: The installer or subscriber initiates the

callback from the subscriber premises (by entering Installer code + # + 1) while

disarmed. All parameters can then be downloaded via the phone lines using a

personal computer.

3. Station Initiated Remote Programming: The operator calls the site from

your office to initiate the download call. The control hangs up and then calls back

the PC via the preprogrammed telephone number. The unit can then be

uploaded, downloaded, or controlled from your office .

4. Telco Hand-off: Allows the installer or subscriber to perform a download

session on the call initiated from the site.

5. Data Encryption: Data passed between the PC and the control is

encrypted for security so that it is very difficult for a foreign device tapped into

the phone line to take over communication and substitute system

compromising information.

Equipment Required

At the premises:

· VISTA-20HWSE and keypad.

At the installer's office/home:

· An IBM PC compatible computer.

Either

a HAYES brand SMARTMODEM 1200 [Level 1.2 or higher external or

Level 1.1 or higher (with 4 position DIP switch) internal style],

a HAYES

brand Optima 24 Plus FAX96 Modem.

· V-LINK® Downloading Software Diskette (at revision level supporting the

VISTA-20HWSE).

· Appropriate interconnecting cables.

Initial Download

Enter Installer code + # + 5. This sets field

95 to 4 rings, and system to “no call-

back” option. The download computer can then call the subscriber, make

connection, and download all programming items.
