Data Back-up &
Recovery
To back up loop data to NVM
A fully allocated loop should be backed up to the Non Volatile
Memory (NVM). The following procedure assumes no password
access is required and write protect is disabled.
¨
Press the Menu On/Off button and then [SetUp],
momentarily press <etc> to select [Backup] and select
the loop number n to be backed up to the NVM. Select
[NVM card] ->[Enter]. A confirmation will be given
on the display:
Loop card n Backed up
Checksum written to card 14
"
It is also important to back up data held in
Card 0 (MCC), to do this follow the above procedures
except after the [Backup] command enter 0, as this is
card 0.
To recover loop data from NVM
¨
On power-up the information stored on the Non
Volatile Memory is automatically recovered to the
Local Controller (MCB) and Loop processor cards.
If there is a recovery failure you will get the following message:
Recovery failed at card x
¨
It is possible to recover data previously backed up to
Non Volatile Memory. The following procedure
assumes there is no password access required.
Press the Menu On/Off button and then [SetUp],
momentarily press <etc> to select [Recover] and select
the card number n to be recovered from the Non
Volatile Memory. Select [NVM card] ->[Enter]. A
confirmation will be given on the display:
Loop card 1 Recovered
"
A warning will be given if the loop map is
different to that previously backed up to the memory
(NVM). For information on how to 'hardware' write protect
NVM see page 44.
To 'software' write protect NVM
Once the NVM is protected it is not possible to write or backup
card data to NVM. To write to NVM it must first be unprotected.
¨
The following procedure assumes no password access
is required.
Press the Menu On/Off button and then [SetUp],
momentarily press <etc> to select [Protect] and then
select [Enable] ->[Enter]. A confirmation will be
given on the display:
NVM is write protected at card 14
4188-856_i2_12/06_Generic Vigilon (Compact + VA) Comms.
Vigilon (EN & BS) Compact (VA) panels
To 'software' write unprotect NVM
Once the NVM is unprotected it is possible to write or backup
card data to the NVM. After card data is backed up to NVM it
must be write protected.
¨
The following procedure assumes no password access
is required.
Press the Menu On/Off button and then [SetUp],
momentarily press <etc> to select [Protect] and then
select [Disable] ->[Enter]. A confirmation will be
given on the display:
NVM is not write protected at card 14
How to electrically erase the NVM
&
Under normal circumstances erasing the
NVM is not necessary as there is only one back up
of the complete system configuration data held at
the panel. The NVM Initialisation should only be
performed by a trained and qualified engineer, as
executing this command will erase all the data
backed up at the panel.
"
To completely erase the NVM you will first
need to switch On the freeblock and disable the hardware
and software write protect. This will allow access to the
initialisation command.
To switch On freeblock
The following procedures assume no password access is
required.
Press the Menu On/Off button and then [Test/Eng] ->
[UserCode] momentarily press <etc> and select [Test] and then
select [Freeblock], press [Next] for controller and select [Enter],
which will display numbers on the top left of the display to show
the freeblock is On.
To initialise Non Volatile Memory
The following procedures assume no password access is
required.
Press the Menu On/Off button and then [Test/Eng] ->
[UserCode] and then select [Card] -> [Init NVM] and then
[Enter].
NVM Card Being Initialised NVM card 14
: 512K bytes
To switch Off freeblock
Press the Menu On/Off button and then [Test/Eng] ->
[UserCode], momentarily press <etc> and select [Test] and
then select [Freeblock], press [Previous] for Off and select
[Enter]. On completion do a display test to clear the freeblock
number display.
