I tried to convert those numbers and they seem too big. I'm pretty sure that the highest decimal number that you would ever have in an EDACS is 2047, because the whole thing is based on 11-digit binary (the first 4 are the agency, second 4 are the fleet, and last 3 are the subfleet). 11111111111 converts to 7FF hex or 2047 decimal. I'm not an EDACS expert, this is just what I have discovered by playing around with the numbers.
