4.6 Using presets
Up to sixteen setups may be stored for the board and recalled either from the board
control or through the use of external GPIs. Presets store board setup data including
operating mode and option card status. It is not possible to recall a preset if the operating
mode or option card configuration is different to those established when the preset was
created. The presets are currently numbered 0-15.
To store or recall a preset proceed as follows:
Disable GPIs – see previous section
Enter the preset menu Menu switch 2 ON (DOWN)
Select appropriate preset with the rotary SEL switch
To store a preset put the Menu lever-1 down and then up again
To recall a preset put the Menu lever-8 down and then up again
The status display will indicate the status of each pre-set as it is selected:
Preset status
Meaning
Valid
A preset has been stored at this location with the same option cards
and mode as now. It can be recalled or over written.
Invalid
The preset cannot be recalled since the mode or option card
configuration has changed. It can be over written with a fresh preset.
Empty
No setup data is stored at this location.
Notes:
Presets cannot be saved or recalled from the card edge unless GPIs are disabled. This is
done to avoid the possibility of GPI inputs causing preset memory data to re-configure
TANDEM-110 at the same time as presets are being updated
