FUNCTION
The Instrumentation Northwest PS9105
Enhanced Pressure Transducer is used to
measure water level. This instruction excites
the PS9105 with a single excitation channel and
measures the sensor’s output on two
consecutive differential analog input channels.
The pressure and sensor temperature are
written into two consecutive input locations
starting at the location specified in parameter 3.
Each PS9105 has 20 enhanced measurement
parameters that are documented on the
calibration sheet. Enter these parameters into
Instruction 29.

*** 105 SDI-12 RECORDER ***
NOTE: Version 1.2 of the SDI-12
specification has been implemented in the
CR10X. Features added in this version are
marked with a dagger (†) and may not be
supported by older SDI-12 sensors.
Instruction 105 allows data to be collected from
SDI-12 sensors. The sensor’s SDI-12 data line
is connected to a control port (C1 or C2). The
SDI-12 ground should be connected to a "G"
terminal on the CR10X wiring panel. SDI-12
power may be connected to 12V.
If multiple SDI-12 sensors are used, up to ten
sensors may be connected to a single control
port, but each sensor must have a unique
address and requires a separate Instruction
105.
