Access Security

Accessing the control from a remote location is protected against compromise by the use of
four levels of protection:
1. Security code handshake: The subscriber's account number as well as an 8-digit ID
number (known only to the office) must be matched between the control and computer.
2. Hang-up and Callback: The control panel will hang up and call the computer back at the
pre-programmed number only if the security codes match.
3. Data encryption: All data that is exchanged between the computer and control is
encrypted to reduce the possibility of anyone tapping the line and corrupting data.
4. Operator access levels: Operators may be assigned various levels of access to the
downloader, each having its own log-on code. The access levels allow the operators
read/write capabilities of the customers' account information. For a detailed explanation
of the access levels, see the downloading software User Manual.
NOTES:
•
Each time the control panel is accessed successfully, a Callback Requested report is sent
to the central station, if programmed.
•
When downloading, the keypad displays MODEM COMM.
•
After each download or a save, an automatic time stamp is done, indicating the date and
time of the last download (or save) and the operator ID number.
•
A complete hard copy of each individual account can be obtained by connecting a printer
to the computer. Refer to your computer Owner's Manual or contact your dealer for
printer recommendations.

Connecting a 4100SM Module for Direct-Wire Downloading

The VISTA-32FB can be downloaded without using a modem or telephone line, but by using
a 4100SM Serial Module and Compass Downloading Software. The direct-wire downloading
connection is to be temporary, and is not part of the permanent installation. Direct-wire
downloading is meant as a tool for the installer during the installation process.
The connections between the control and the 4100SM are different than those shown in the
4100SM Installation Instructions. See the diagram below for correct connections. Instead of
using the green wire referred to in step 2 of the IN CASE OF DIFFICULTY section of the 4100SM
Instructions, use the violet wire.
Connector J8 on the main PC board (see the Summary of Connections diagram on the inside
back cover of this manual) is intended to be interfaced to either a local serial printer (see
Event Log printer Connections in Section 17: Event Log Options) or a computer. Make
connections to a computer as shown below. Note that the violet wire connection for a
computer differs from that used when connecting a serial printer.
