Direct-Wire Downloading
The VISTA-50P/VISTA-50PUL can be downloaded
without using a modem or telephone line 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 Figure 7-
1 for the correct connections. In addition, in
place of the green wire, referred to in step 2 of
the “IN CASE OF DIFFICULTY” section of the
4100SM Instructions, use the violet wire
instead.
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 SECTION 3:Installing the Control) 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.

Telco Handoff
Telco handoff is another method of getting on-line with the downloader. The installer or customer enters the User Code
+ [#] + [1], while on the phone line with the computer’s modem phone line. The customer will get cut-off and the panel
and download computer will establish a connection.
