Does anybody know if there's a way to activate a task in the old Cambridge flight recorders WITHOUT using the separate display unit? Tasks can be loaded (via a serial cable) from a PC running the Cambridge Aero Explorer software, but they don't appear in the resulting flight logs unless they are "activated" from the display unit. I'm hoping there is an alternative method, e.g., sending some secret phrase to the thing via the serial port. Nothing fancy needed, just make "Task A" active. This is to enable electronic declaration of goal flights.
