Create GP2 Program
3.
Address
: Enter the WET150 address so the GP2 will know
which sensor to contact.
You must do this
.
Use DeltaLINK, SDI-12, Transparent mode (or a WET150 Meter)
to give it a unique address
before
putting it on the SDI-12
network with other sensors, or else the network will crash.

4.
Mode
: The default WET150 sensor type uses the SDI-12
Sequential
data measurement and reporting method.
on page 27.
5.
Additional
: No action required. The default value cannot be
changed. The additional features are of use to less capable
loggers from other manufacturers, which can’t do maths as well
as the GP2).
6.
Send data Command
: No action required. Your GP2 logger
knows which D command to send, so this is not something you
need to worry about.
(Note for other logger users: The Dn command is sent by the
logger to retrieve the results when the sensor is ready (n can be
0 to 8). In reply the sensor may send up to 76 characters to the
logger. The number of characters required for each reading can
vary: depending, for instance, on whether readings are
concurrent or sequential. So additional commands, D1
–D8, are
available if necessary.
