 I have a Chelton system and an EAU (("Engine Air Unit" or "Engine and Airdata
Computer")providing engine and air data.  The EAU (mine is model EUB2C I
think) is manufactured by Grand Rapids Technologies Avionics but I can't seem
to find a manual on their website.
 Does anyone have an EAU manual or a link?  I need some info on setup
parameters (both pages).   ...Clark Still (N750S)
