Using Presets 

Up to sixteen setups may be stored and recalled from Statesman, the card edge control or by 
external GPIs. Presets store board setup data including operating configurations and option 
card status. It is not possible to recall a preset if the option card configuration is different to 
that established when the preset was created. The presets are numbered 1-16. 

To store a preset proceed as follows: 

 

Ensure ‘GPI controls preset recall’ is unchecked 

 

Select appropriate preset by checking the Preset Number radio button 

 

Click on ‘Store’ to save setup data into the selected preset 

To recall a preset proceed as follows: 

 

Select appropriate preset by checking the Preset Number radio button 

 

Click on ‘Recall’ to recall setup data from the selected preset 

‘GPI controls preset recall’ should not be checked whilst presets are being created or recalled 
by this menu to prevent inadvertent GPI operation. Enable ‘GPI controls preset recall’ when 
finished if required.
