DOWNLOADING
Downloading is the use of an IBM compatible computer
to program the PC4000 system. The computer can be
located either on site, or communicate over the phone.
The DSC downloading package version 5.0 or later
supports downloading to the PC4000.
See the downloading manual for details on specific
capabilities and the "DLS" section in the PC4000
Programming Guide for programming DLS options.
Downloading over phone lines
Make sure the "TIP" and "RNG" terminals are connected
to the phone line. Program the access code and the
panel I.D. code in the PC4000.
The PC4000 panel can call the computer, or vice versa.
"Ring Detect" or "User enabs DLS" must be enabled for
the PC4000 to detect when the phone line is ringing, the
time the computer is calling the panel.
The number of times the panel allows the phone line to
ring before answering is programmable, and the default
setting is 8 rings.
If the panel calls the computer, enable "User call up"
and program the phone number of the computer. Initiate
the call by entering [ ][6][Master Code][7].
The TM1 or RJ31-X are jacks which connect single wires
into one end, and a telephone cord into the other end.
Although this jack is not necessary, it simplifies the
connection of the PC4000 to a modem. If a TM1 or
RJ31-X are not readily available, use a telephone cord.
Plug one end into the modem, cut off the other end, and
wire the green and red wires into the TIP and RNG on
the PC4000.
Downloading with an On-site Computer
Phone lines are not necessary to download to the panel
if the computer is at the same location as the PC4000.
The tip and ring lines of the modem can be directly
connected to the tip and ring terminals on the panel.
A DTS-1 must be connected to the lines and in the local
mode.
Program the downloading access code and panel I.D.
code.
Program a zone for "Forced Answer". See "Zone Type"
in the Programming Guide. This zone is only meant to
be temporary, to initiate downloading. It can later be
changed back to the required zone type.
Make sure the access code and panel I.D. code are the
same in the panel and computer. A telephone number
must be programmed into the computer to initiate
communications, and any number entries are accepted.
Activate the computer to call the panel. When the
computer indicates "Dialing...No dial tone", press the
dial tone button on the DTS-1 until the modem dialing
the phone number is heard. Trip the zone programmed
for "Forced Answer". The panel will seize the phone line
and initiate communications with the computer. The
computer will then display the message "Connected to
panel..." and continue with communications.
The DTS-1 must remain connected to the phone line in
local mode during the downloading.
