Note : iop universal is now split into iop wet and iop dry builds, and that
"dry" and "wet" refer to the IO mother board type and so may differ from 
other usages of the term

Support for motion sensor formats required by MR7
Simrad EM1000, Simrad EM3000, TSS1 and NMEA-$PASHR

All data is sent up in current SIMRAD format

EM3000 currently is set to accept a status of AX and 9X data is sent up
i.e. even if quality is bad

NMEA apparently has several formats and the one implemented is POSMV per spec

The time delay port is enabled on port 3 with same format as other ports -
port number, size data

LED indicators are same as previous revisions of iop universal
