Section 3 - Activation of Selected Functions 33
Modem initialization
The program initializes the modem after the „MODEM” item is selected from the
„COMMUNICATION” menu. In case of any trouble, the program will display one of
the two messages:
• which means 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 2400Bps). The fast modems of a new
generation require some extra commands being added to limit their operation
speed.
Remote communication procedure:
• program in the control panel:
- FS-2: panel communication code (identifier by which the program
recognizes the alarm system)
- FS-3: computer communication code (identifier by which the control
panel recognizes the computer authorized to establish connection)
- FS-4: computer telephone number (which is not necessary)
- FS-5: “auto download” option (downloading activation from the outside),
“double call” option (any setting) and the FS-101 – number of rings
before answer – if communication is to be initiated from the computer
• start the DLOAD10 program, select the CA-10 control panel (CA10v1, 2, 3,
4) - program version 4 corresponds to the CA-10 plus panel, e.g. by
opening the data of such a panel and, select the “MODEM” item from the
„COMMUNICATION” menu.
Note: The communication codes and the „double call” option settings must be
identical in the control panel and in the alarm system computer data.
Telephone connection with the control panel will be set up automatically after
selecting any communication command in the program (Read, Write, Event log
read, ON-LINE mode). You can also start communication from the panel with the
user function 0.
Telephone communication error messages:
• “modem not responding” – the modem has not acknowledged the dialed
number (a rare case, 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 was off hook but did not answer the modem signal
because it was much corrupted,
– the control panel was off hook but did not answer the modem signal
because it was not in the transmission format V.21 or BELL 103
(incompatible or incorrectly configured modem),
• “communication code not acknowledged” – the control panel
established connection, but the computer communication code does not
correspond to that programmed in the control panel in FS-3 - the panel
disconnects,
