3.5mm Plug Wiring
The EC-5 comes with a 3.5mm “stereo plug” connector.
This allows for rapid connection directly to Decagon’s
Em50 and Em5 loggers and the ProCheck. Below is a
diagram showing the wiring configuration for this con-
nector.

Wiring to Non-Decagon Data Loggers
Models with stripped and tinned leads are pre-config-
ured for connecting to non-Decagon data loggers. Sim-
ply wire the lead into the data logger as described in
“Connecting to a Data Logger” in Chapter 4.
If your model uses the standard 3.5mm plug, you have
two choices when attaching the sensor to non-Decagon
data loggers. First, you can clip off the plug on the sen-
sor 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 sensor becom-
ing un-plugged; however, it then cannot be used in the
future with a Decagon Em50 or Em5 logger. The other
