DGPS ENCODEMENT
There are some things that must be set up before the LH 665 can log positional
data to a data card. These settings are the same for all operating modes and we
refer to the DATA CARD chapter in this operator’s manual.
GPS SETUP
If an ADD-ON GPS model 3000, 3050 or 3100 is fitted there are some
encodements needed for correct operation. A description of these encodements
follows:
Step Key Procedure

NMEA MESSAGE
The ADD-ON GPS module uses the Trimble TSIP protocol for transmitting
positional data to the LH 665. This means that NMEA strings are not used and are
not shown under RAW-GPS diagnostics.
GPS/PORT CONFIGURATION
It is not necessary at present to change any of these settings and we recommend
therefore that no encodements take place.
