Consider the following points when wiring sensors:
•
The maximum wire length from a sensor to the Solar DataSnap is
200 feet.
•
For convenience, the green terminal block can be removed from
the SDI-12 port while wires are connected to it. Simply pull on the
block to remove it from the inside of the Solar DataSnap. To
connect the terminal block, insert it back into the Solar DataSnap
with the screws facing right.
•
One to two sensors can easily be wired directly into the green
terminal block as shown in figure 5 above. To do this, insert all red
wires into the topmost portion of the terminal block and tighten the
screw to secure them in place. Repeat the procedure for the white
wires in the middle portion of the block and the blue wires in the
bottom portion of the block.

•
When connecting up to 10 sensors to one Solar DataSnap, a wire
splice may be necessary. This can be done by connecting all the
red sensor wires to a separate, single wire and then connecting the
single new wire to the terminal block in the appropriate position.
Follow the same procedure to connect the white and blue wires.
The wiring should look like figure 5. When the block is connected to
the Solar DataSnap, the location of the colored wires must match
the colors on the DataSnap.
Configuration
A DataSnap must be configured prior to its first use. The
SnapView software guides you through the configuration process
in a few simple steps. To access the Configuration screen, click
on the ‘Config’ button at the top of the screen. This will display the
Configuration wizard.
The SDI-12 protocol requires that a sensor be given a specific address. All
communication with a sensor is based on this address. When a sensor is
added to a DataSnap, the sensor’s address is stored in the DataSnap.
