your controller, see page
10. Choose how you want to use the card with the controller:
– Turn off the controller, put the card in, and turn the controller back on. The
controller will load the strategy from the card (verifying the signature if it is an .ssd file),
switch to the new strategy if you're using background downloading, and run the new
strategy if you set it to autorun. If it's not set to autorun, you have to start the strategy
manually using PAC Control or PAC Terminal. For firmware versions older than 9.0a, if you
checked the Save to flash memory box, the strategy is saved to flash. For firmware 9.0a or
newer, see step 11.
– Put the card in while the controller is running. The controller will check that the
stratregy differs from the existing one, verify signature on an .ssd file, load the strategy,
switch to the new strategy if you're using background downloading, and then run the
strategy only if the existing strategy was running when you put the card in. If the existing
