7.1 Wiring
The Wintersense SDI-12 cable has an M12 connector on one end and terminates in individual
wires at the other. See
Figure 7-1 (p. 8). Connect the wires in the order shown in the following
table.

C and U terminals are automatically configured by

.
If multiple SDI-12 sensors are connected to a data logger, Campbell Scientific recommends using
separate terminals when possible. However, multiple SDI-12 sensors can connect to the same
data logger control or U terminal. Each must have a unique SDI-12 address. Valid addresses are 0
through 9, a through z, and A through Z.
For the CR6 and CR1000X data loggers, triggering conflicts may occur when a companion
terminal is used for a triggering instruction such as
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
. For example, if the Wintersense SDI-12 is connected to C3 on a CR1000X, C4
cannot be used in the
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
instructions.

loggers. If your data acquisition requirements are simple, you can probably create and maintain a
