Set up
a. Positioning
Install the modem at a minimum height of 2m and not glued to a wall, ideally offset by at least 20cm.
For best results, it is advisable to move the antenna up and clear of any metal obstacle within a radius of
1 meter if possible.
b. Modem connection
Terminals:
Antenna (SMA):
Before powering the product, a 50Ω / 868MHz antenna must be connected, either
directly to the SMA connector or via a 50Ω cable in case of antenna offset.
Alimentation device (Lower terminal):
The ACW-GW module must be powered with a DC power supply between 10V and
30V that can provide a minimum current of 100mA.
Alimentation analogical sensor (Lower terminal):
The analog sensor can be powered at the time of measurement directly with the output
OUT of the ACW_DA. To do this connect its power supply to the pin "OUT" and its GND to
that of the external power supply (or terminal GND). This output can deliver a max current of 1
ampere with the supply voltage (10 / 30V). Before each analog measurement, the sensor will be
powered for 0.5 seconds. If you want to permanently supply the sensor, do not use the "OUT"
connector and connect it directly to the terminals of the external power supply.

Analogical input (Upper terminal):
It is the analog input current or voltage that comes from the sensor.
To choose a voltage or current reading, in addition to indicating it in the configurator (see Modem configuration
section), it is necessary to switch the slide switch to the correct position. For use with a 0-10V
sensor, it is necessary to switch the switch to the high position (SMA side). For a
use with a sensor 4-20mA, it will switch the switch down (USB side).
Numerical inputs (Upper terminal):
You can connect up to two digital inputs. It is necessary to inject a voltage between 10 and 30V continous
or to leave the circuit open.
USB:
The USB connector is used to configure the ACW via a PC and a USB cable. for more detail. The
configuration must be done with the device powered by 10 / 30V.
c. Lights meaning
When the power is turned on or after removing the USB cable, the green LED (upper LED) lights up for
a brief moment signifies that the ACW is starting up properly. If a problem occurs during this phase, the
red LED (bottom LED) will illuminate for a brief moment to testify to this state.
In USB configuration mode, the green LED flashes until the configuration is completed and the USB cable
is removed.
Overall in normal operation, the illumination of the green LED attests to a radio communication. The
red LED illuminates to show any errors that may occur.
d. Pushbutton
The push button, located on the front of the box, allows to emit a test frame to validate the installation
on site. A test frame is constituted as follows.

e. 10/30V digital inputs
The digital inputs IN1 and IN2 have the following function:
Either trigger the analogue measurement on each rising or falling edge, then send the measured value
to the radio (Sigfox / LoRaWAN).
These inputs must be controlled by a voltage between 10V and 30V for an active state. The consumption
of these inputs is 30mA max at 30V and 10mA max at 10V.

ATIM_ACW-DINDA_UG_FR_v1.5
Modem configuration
Download and install the configuration software '' setupACW.exe '' at:
http://www.atim.com/produit/atim-cloud-wireless-acw/
Connect the module to your computer with a USB cable then launch the software, do not forget to supply
the ACW_RS in 10 / 30V.
When you connect the module, the software window changes to allow you to access the main features.
Automatically, the current configuration of the connected module is retrieved and displayed.
The different configuration modes are described below. Once the configuration is the one you want, you just
have to click on the Write key. After a few seconds of waiting, a message appears next to it to inform you if
the module update succeeded or failed.
Note
It is in this phase that the module is updated with the time of your PC.
Once the configuration is complete, do not leave the module connected to USB. This mode of
operation is very energy intensive. When you remove the USB link without disconnecting the
battery, the module automatically returns to normal operation. At power up, 5 test frames are
emitted every minute to validate the operation.

ATIM_ACW-DINDA_UG_FR_v1.5
a. Common configuration (calibration)
Note
In the lower part, you can read in real time (periodic sampling of 2s) the value measured by the
module.
✓Analog measurement
Here you can choose the type of measured value (current or voltage). You must also make
this choice on the slide switch (see Set Up).
✓Calibration
The 'Unit' field allows you to specify the unit of measure for data readability, up to 4
characters long. The 'minimum value' allows to set the minimum value for a sensor output
of 0V or 4mA. The 'maximum value' is used to set the maximum value for a sensor output
of 10V or 20mA.
✓Offset
Offset correction of the sensor + module assembly. Enter the value to add or subtract to the
measure to get the correct value. It is not recommended to correct the offset for an input of
0V or 0mA.

12
ATIM_ACW-DINDA_UG_FR_v1.5
b. Periodic mode configuration (SF8/LoRaWAN)
In this mode of operation, an analog measurement is performed and sent in radio every X time (X is a
configurable value).
✓Statement period
This menu allows you to configure the elapsed time between 2 sending of data. This
period is between 10min and 23h50min with a step of 10min.
✓Threshold
The high and low thresholds are not used in this mode, but they are still transmitted by
radio. Depending on your needs you can choose to configure them.

13
ATIM_ACW-DINDA_UG_FR_v1.5
c. Threshold mode configuration (SF8/LoRaWAN)
In this operating mode, an analog measurement is performed every X time (X is a configurable value). In
the case where the measured value is not between the two thresholds (configurable) the value will be
transmitted in radio.
✓Sampling period
This menu allows you to configure the elapsed time between 2 analog acquisitions. This
period is configurable every 15min, 30min, 1 hour or 2 hours.
✓Temperature sent
This makes it possible to force the sending every X time. Three times are configurable.
To activate and configure them you must check the appropriate boxes.
✓Threshold
During a measurement, it is compared with the high 'High' and 'Low' low thresholds. If
the measurement is outside these thresholds, the value will be sent only if the previous
measured value was between these two thresholds.

14
ATIM_ACW-DINDA_UG_FR_v1.5
Note
When a threshold is reached, it changes value, 5% greater for the low threshold and 5% smaller for the high threshold.
5% of the range of measurement. For example, if the min value is -2 and the max value is 14, Se will be 5% of 16

15
ATIM_ACW-DINDA_UG_FR_v1.5
Operating example
In this example the 'Sampling period' is set every hour and only one 'temperature sent' is set to 13h. The
min value is 0 and the max value is 10. The threshold values could be 5V and 8V (black curve). This means
that if the measured value is outside thresholds (5V and 8V), the thresholds will be changed to 5% and will
become 5.5V and 7.5V (curve in gray).
The blue curve corresponds to the measured analog signal. The orange curves correspond to the analog
measurements. The green curves represent the sending of the measured analog value which has just
crossed a threshold. The yellow curve represents the sending of the measured analog value when the
'temperature feels' is reached.
