1
Classic 2000 Mk II panel reports
this message: “NDC EEPROM
CORRUPT.”
ZNDC has not yet been
programmed.
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.

ZNDC attempts to dial, but no
connection is made. Or, ZNDC
sounds a series of clicks, but does
not dial. The Trouble and Line Fault
LEDs activate on the board, and a
trouble is reported at the panel.
Wrong phone number or
No phone number has been
programmed in at all.
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.

ZNDC is connected, but will not go
Online with ZNDC_Prog. PC
reports this message: “Trouble
writing to ZNDC.” ZNDC may also
exhibit the same symptoms as
mentioned above.
Wrong COM port.
COM port disconnected.
Wrong or damaged PCI cable.
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.

Everything seems to be working,
but ZNDC won’t go online with the
Programmer.
COM port is occupied.
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.
