now we are getting somewhere......
i dont understand, your key assignments can't be blank, you printed them off to edit your keymap file. you didn't move or delete the file by accident did you?
the PMDG MCP/EFIS are controlled by keystrokes and what the VRInsight MCP/EFIS does is
send in single or repeated keystrokes to increase/decrease values in the software.
if there are no assignments in your PMDG key menu, then the keys that your VRInsight unit sends will not be actioned because the keys its sending are not assigned.
ok, email me at ian@737ng.co.uk and when i get home, i'll send you my 737kbd.ini file and my serialfp2 dat (keymap file).
let's see if we can sort this out.
talk to you later.... ian
