AdderView DVI Installation and Use Page 20

option switch 7 to the OFF position to exit upgrade mode and start normal operation.

firmware version query function.
Some useful issues to bear in mind when performing flash upgrades
The upgrade program rewrites the AdderView's firmware code. If the upgrade
process is interrupted then the AdderView will have invalid code and will not be able
to operate. It is therefore good practice to ensure that the upgrade process is always
fully completed. A partial or failed upgrade may be rectified by performing another
upgrade. If the upgrade process is interrupted accidentally then you should
immediately repeat the upgrade process without moving switch 7 from the flash
upgrade (ON) position. Switch 7 forces the AdderView into flash upgrade mode and
prevents the upgraded code from being run. Running faulty or partially upgraded
code may have unpredictable results and may damage your AdderView or
computing equipment. For obvious reasons, the code that the AdderView uses to
perform upgrades is not itself upgradeable - a common problem on some flash
upgradeable products that could effectively be destroyed by a partial upgrade!
WARNING - Running faulty or partially upgraded code may have unpredictable
results and may damage your AdderView or computing equipment.
