Please, we need help!!!

What was done (see attached files):
Konnect was connected to the Kflop through jp6 whith a ribbon cable that was lying in the kit;
in a C-file a Konnect board was initialized by a two strins from a manual:
InitAux();
AddKonnect(0,&VirtualBits,VirtualBitsEx);
hit the "init" button;
Four step-motors work propperly.

But when the input is activated by applying voltage to Konnect board, no reaction takes place in the Kmotionion console,
as well as in the Digital I/O window. But the green LED in front of the input on the Kmotion board lights up.
On a Konnect board pin 24 activated. Sending in console "readbit1048" always return "0". In both cases - LED on, or LED off (when we disconnected power).

So, we can't setup pneumo relay and home limits. And we don't understand, - what we did wrong?
