Remote communication:
•
connect the telephone line to the TIP and RING terminals,
•
program in the control panel:
−
FS2
: panel communication password (identifier by which the program recognizes the
alarm system),
−
FS3
: computer communication password (identifier by which the control panel
recognizes the computer authorized to connect to panel),
−
FS4
: computer telephone number (which is not necessary but ensures a better
protection against unauthorized access),
−
FS5
: “external downloading” option, “double call” option (any setting) and the
FS101
– number of rings before answer – if communication is to be initiated from the PC.
•
start the DLOAD10 program, select the control panel type (e.g. by opening the data of
such a panel) and, from the menu “
Communication
”, select the “
Modem
” item and the
„remote” connection mode;
•
apart from the communication codes, conformity is also required between the above
mentioned options in the control panel and the security system data in the computer.
It is also possible to initialize communication with the panel with the user
function 0
.
Having established connection, read the control panel data and then you can proceed to
reading the events, programming parameters, etc.
Messages on troubles during modem initialization:
•
„
modem not responding
” – a technical problem with communication with the modem,
e.g. an incorrect COM port number, conflict with the Windows system drivers.
•
„
initialization error
” – wrong command initializing the modem.
Correct initialization of the modem does not mean it is properly configured to work with the
control panel. The first initializing commands, as suggested in the program, are sufficient
for a correct operation of most older-generation modems (i.e. modems with a maximum
speed of 2400 Bps). The fast modems of a new generation
require
some extra commands
being added to limit their operation speed.
Messages on telephone communication errors:
•
„
modem not responding
” – the modem has not acknowledged the dialed number
(a rare occurrence, usually a problem caused by modem hardware or e.g. missing the
“V1” initializing command),
•
„
connection failed
”, „
no control panel signals
”, „
poor quality of connection, no
control panel handshake
”
−
connection with the control panel was unsuccessful,
−
the control panel picked up the phone but did not answer because the modem
signal was corrupted,
−
the control panel went off-hook, but did not answer the modem signal, because it
was neither V.21 or BELL 103 transmission format (incompatible or
wrongly
configured
modem),
•
„
communication password not acknowledged
” – the control panel established
connection, but the computer communication password does not correspond to the one
programmed in the control panel in FS3 function – the panel disconnects,
•
„
connection interrupted
” – the control panel stopped answering the computer signals.
Note:
If the control panel answers the call but fails to establish communication and
disconnects, while the “double call” option is deactivated, it will be answering no
calls for the next 5 minutes.
