Part # MAN-ZNDC-01
Solution
This message will come up only the
first time the ZNDC is hooked up, or
after it has been reset to factory
defaults. It basically means that the
ZNDC has not been programmed to
communicate with a PC or a
receiver. This message will remain
on the panel until you have written
to the ZNDC, and the panel has
been reset.
Go to your ZNDC_Prog
programming software, to your
Account Data tab. Enter in the
correct phone number.
Note: Some phone systems require
the user to dial a '9' to pick up an
outside line. If this is the case in
your building, simply put a '9'
followed by a ',' (comma) before the
phone number.
After entering the correct
information into ZNDC_Prog, write
to the ZNDC.
Make sure the PCI cable that came
with the ZNDC is connected to the
PC at either COM 1 or COM 2.
(Some computers come with more
COM ports, but the ZNDC can be
programmed only for ports 1 and 2.)
At the PC, make sure that the COM
port set in ZNDC_Prog is the same
as the port actually being used. To
change the port in ZNDC_Prog, go
to the Communications tab, and
click once on the COM port listed
just below the Offline / Online sign.
If you have to use an extension
cable between the PCI cable and
the PC, do not use Null Modem
cable. Instead, use a straight-
through, M-to-F DB9 cable.
Check to see if any other programs
(such as PC3K or PC1K) are open
and using the COM port
themselves. Note: the computer
cannot share one COM port with
two programs.
