How to calculate DME

[Verley]

Hello,

I'am working on a VB pogram to monitor 7 segment displays on my radiostack. There for I need to read out the DME. I get a value of 5 numbers when I use offset 0C29 (for DME1). Can You tell me how to recalculate these 5 numbers to get the distance in nm? :?:

Regards,

:wink:

As clearly documented (!), they are not "5 numbers" but an ASCII character string, ready for display. e.g "18.9" for 18.9 nm. If you want them in binary you'll need to convert them from character form to binary using something like sscanf or whatever the equivalent is in the language you are using.
