Preparation
You need to assemble the following equipment:
Item
Accessories / notes
GP1
Mounting kit (GP1-MP1)
Serial cable, small screwdriver and PC software on
CD (included with GP1)
SM300
Logger cable (SMSC/sw-05)
Extension cables may be required (see section 1.1)
Note that the SM300 includes a built-in temperature
sensor but this can only provide soil / substrate
temperature readings when the SM300 is fully buried.
Cable to solenoid
Round cross-section 2-core wire
3-way
connector
block
You will need to put the connector block into a
sealed box if connecting to the solenoid valve in a
wet area.
Tape and/or cable ties
For keeping wires tidy and preventing accidents.
These may also be helpful:
SM300 + HH2
Useful for checking range of moisture contents
during set up and adjustment.
Note that the HH2
does not display readings from the SM300 temperature
sensor.
You will also need access to the following:
Tools
Wire cutters & wire strippers
…
An electrical multi-meter with audible short circuit
warning is also very useful.
Ladder
If some of the wiring will run overhead.
Portable computer
with Windows 98, XP,
Vista or 7
For configuring the GP1.
It is even more convenient to do this with an iPAQ
(see section 7), but check for compatibility.
