You might be using old version of Dashboard and you have an old firmware on M10.
Use C:\Program Files\Digi\Digi m10 JumpStart Kit\tools\m10UpgradeUtility.exe tool in your PC to upgrade modem firmware.
Latest firmware can be found in http://www.digi.com/support/productdetail?pid=4145&type=documentation
126.96.36.199 > http://ftp1.digi.com/support/patches/m10/m10CoreModem_2006.ldr
After upgrade, uninstall Digi Dashboard completely.
Go to regedit and delete
If Win 7(64-bit) -> HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Digi\Digi m10 JumpStart Kit
If Win 7(32-bit) -> HKEY_LOCAL_MACHINE\SOFTWARE\Digi\Digi m10 JumpStart Kit
Note :- Windows 7 is not officially supported , but you can work by starting it in Win XP Compaitability mode

If you still have issues download any serial terminal application like “Hyperterminal” or “Teraterm” and connect M10’s Debug port in 115200 baudrate.
Turn on module and in serial console do 2<enter>48<enter>0<enter> , which will do a factory restore on module.
