4 CONNECTING THE SRS SRS Sensors
tions. First, you can clip off the plug on the sensor cable, strip and
tin the wires, and wire it directly into the data logger. This has the
advantage of creating a direct connection with no chance of the sen-
sor becoming unplugged; however, it then cannot be easily used in
the future with a Decagon data logger. The other option is to obtain
an adapter cable from Decagon. The 3-wire sensor adapter cable has
a connector for the sensor jack on one end, and three wires on the
other end for connection to a data logger (this is referred to as a
“pigtail adapter,” Figure 10). Both the stripped and tinned adapter
cable wires have the same termination as seen above; the white wire
is excitation, red is data output, and the bare wire is ground.
Note: Be extra careful to secure your stereo to pigtail adapter con-
nections to ensure that sensors do not become disconnected during
use.
