good morning peter,
my appologies if i didn't explain myself properly, so let me have another shot at it :o)
the PMDG737NG Idle/Cutoff Levers respond to your FSUIPC option of 'Toggle Engine# Fuel Valve' in the dropdown menu in the Buttons Page of FSUIPC.
i am currently operating the levers this way via 2 microswitches in my TQ connected to a BU0836 card which FSUIPC recognises.
the option in FSUIPC is for a 'Toggle' only. so sometimes the synchronisation of the hardware and software Idle/Cutoff Levers on startup is not right. i.e. PMDG
will start with the levers in Idle and the TQ levers will be in cutoff. so only having a Toggle option available means getting out of the cockpit to synchronise them with a mouse click.
i dont have a keyboard or a mouse in the cockpit at all, everything is controlled by a switch or pushbutton sending keys or key2mouse.
what i was asking is would you be able to add distinct ON/CLOSED commands for the Engine Fuel Valves in a future version. for example Control Sent When Button Pressed
'Engine 1 Fuel Valve Closed' and Control Sent When Button Released 'Engine 1 Fuel Valve Open'.
this is the only thing i do not have 'exact' control over and when i have visitors to the cockpit, they tend to be asking questions and distracting me and very often the synchronisation of the fuel levers gets overlooked.
hope i explained it better this time.
thank you sir, have a great day. regardsian
