1.1 Overview
1.1.1 GX70SM Wireless Input Unit
The GX70SM is a compact, battery-driven analog input unit that uses 920 MHz specified low
power radio. Because it is battery-driven, it can collect data in a variety of locations.
It connects to a SMARTDAC+ GX20, GP20, or GM10 coordinator over a multi-hop wireless
link, and allows data collection and status display of the GX70SM on the GX20/GP20/GM10.
If you turn off the wireless function, you can use the GX70SM as a standalone data logger
and collect data. This will extend the battery life.

1.1.2 WirelessInputUnitConfigurator
Wireless Input Unit Configurator is a software application for configuring and performing
maintenance on the GX70SM.
Input configuration, wireless configuration, input calibration, and firmware updating are
possible by connecting to the GX70SM through USB.

GX70SM
Logging data stored in the GX70SM can be retrieved and saved as a file in the PC.
When the GX/GP/GM fails to acquire GX70SM measurement data because the
communication between the GX70SM and GX/GP/GM is disconnected or because of some
other reason, a logging data file can be used to interpolate the data during which acquisition
failed.
Note: There are certain GX/GP/GM settings that need to be configured to combine data. See
section 2.7, “Saving Logging Data to a File and Combining Logging Data.”
For details on setting the type of data to record, see the following manuals.

•Measurementmode
•Configurationmode
Measurement mode is used to perform measurement.
Configuration mode is used to configure input settings and wireless settings, retrieve logging
data, calibrate the input, and so on.
You can change the operation mode using the GX70SM operation mode switch.
See section 1.5, “Setting the Operation Mode of Wireless Input Units” on page 1-11.

1.2.2 Measurement
With two universal input channels, the GX70SM can measure temperature (thermocouple,
RTD sensor input), DC voltage, DC current (using a shunt resistor), and digital input
(contact, voltage).
In addition, the built-in humidity sensor (/RH option) can be used to measure one channel of
humidity.

1.2.3 Measurement Mode
There are two measurement modes.
Standard mode Powerfrequencynoiseridingonthemeasuredsignalisrejected.Selectthe
power frequency for your region using the Wireless Input Unit Configurator.
The battery life (running time on battery) is shorter than in battery-save mode.
Battery-save mode Powerfrequencynoiseridingonthemeasuredsignalisnotrejected.
Depending on the measuring range, measurement errors will be large due to
the effects of noise, and the values may fluctuate.
The battery life (running time on battery) is 1.3 to 1.5 times longer than in
standard mode.

1.2.4 MeasurementDataLogging
Measurement data of each scan interval is sent to the GX/GP/GM as well as saved in the
GX70SM as logging data (up to 4500 points per channel).
When the data becomes full, the oldest data is deleted to save new data.
Even when an error occurs in the wireless communication with the GX/GP/GM,
measurement data is backed up for a certain period.
Logging data can be retrieved using the Wireless Input Unit Configurator and saved as a file
in the PC.

When the GX70SM battery voltage becomes low, a low battery warning is indicated with an
LED.
The GX/GP/GM can monitor the GX70SM battery status and generate a warning output
(relay output) when appropriate.

1.2.9 DataDropoutDetection(GX/GP/GM)
The GX/GP/GM can detect GX70SM data acquisition dropouts caused by communication
errors or the like by collecting the GX70SM data serial numbers.* When the data serial
number received from the GX70SM does not change over a specified period, the GX/GP/
GM decides that a data dropout has occurred.
The occurrence of data dropouts can be output and recorded as alarms.
You can view the alarms that have occurred on the monitor view. Further, they can be used
to trigger internal switches, relay output, and e-mail transmission.

When a battery error, operation error, communication disconnection, or the like occurs on
the GX70SM, device information can be output using a FAIL relay (/FL1 option).
