Power port:
The Soil EC Surveyor is shipped
with an accessory power cord.
If an alternative connection is
desired, make sure that the unit
is properly connected to a power
connection that is not controlled
by the ignition switch. If
connecting directly to the
battery, we suggest a 3-amp in-
line fuse is installed between the
battery and the instrument. EC Signal:

either VTG or RMC strings
at a 1hz rate, at 4800 baud,
8 data bits, 1 stop bit, no
parity.)
