Operating
a. Operating mode
The operating of the ACW-TCR deals with several modes:
-Exploitation mode: this is the default mode when starting the product. In this mode, the module periodically
sends measurements according to the configuration applied (if the product has never been configured, the
factory configuration applies, cf. Factory settings).
-Deep sleep mode: this standby mode mainly allows the product to be put to sleep from the moment the
product is powered on until it is installed on site. In this mode, no measurement or radio communication
function is possible.
-Confirmation mode: this mode is active FIVE minutes after exiting deep sleep mode and allows configuration
of the product in Bluetooth using the PC configurator. In addition, radio frames are sent every minute
(therefore five frames) to ensure that the product is properly commissioned. After these five minutes, the
product returns to operating mode and Bluetooth is deactivated (possibility of reactivating it via Downlink).
-Pairing mode: this mode is active after exiting dee sleep mode and allows to pair to the network.
-Fault mode: This mode allows the normal operation of the module to be interrupted when a critical event
occurs. The nature of the event can be multiple:
•Empty battery (battery voltage less than 2.2V)
•Error on the radio module
•Error when automated tests
•Error in the application
Entering Fault mode is indicated by a flashing RED LED of the product.
If the error does not come from the radio module, the product will send 3 radio frames every 24 hours containing the
error code (s) (see chapter Frames format for error codes). In addition, the product will emit luminous warning
depending on the nature of the event.
Once in this mode, the module must be restarted (by disconnecting and reconnecting the battery or by command in
Downlink) to return to its normal operation.
At any time, it is possible to identify which mode the product is in by bringing a magnet close at least for 2 seconds to
the diamond mark on the case. The product led will light up in one of these colours depending on the mode:
for operating mode
for configuration mode
for deep sleep mode
for fault mode
for pairing mode

ATIM_ACW-TCR_UG_EN_V1.0
b. Product start up
In most cases, the ACW-TCR is started up before delivery (battery packs already connected) and then placed in deep
standby to limit consumption.
To place the product in its operating mode, bring a magnet close to the diamond-shaped marking on the box for 6
seconds. During these 6 seconds, the product LED should flash WHITE and then GREEN after six seconds to indicate
that the product has started up.
The ACW then enters the network pairing phase. During this phase, a FUSCHIA light signal with a fading effect indicates
that the search phase is in progress.
If the connection is successful, the product will emit a light signal depending on the quality of the network:
•GREEN light signal: good quality of network
•YELLOW light signal: low quality of network
•ORANGE light signal: bad quality of network
•WHITE light signal: no information on the quality of the network
The module will then enter its operating mode and start to send information to the network depending on the
configuration.
In case of connection failure, the ACW will return to its fault mode because no radio transmission can be made.
WARNING: To have information on the quality of the Sigfox or LoRaWAN network, it is necessary to provision a
Downlink. It is this that will determine the quality of the network. The product emits at startup (directly for Sigfox
after the Join phase for LoRaWAN), a test Uplink described in the Classic frame chapter (type of frame 0x02). If a
Downlink is provisioned, information on network quality will then be fed back by the ACW (light signal). If no
Downlink is provisioned, then ACW will always display the WHITE light signal.
c. Test frame emission
When the product is in its operating mode (and only in this mode), it is possible to send a test frame (which avoids
waiting for the next measurement frame) including a measurement sample.
To do this, simply bring the magnet closer until the GREEN light signal goes out. The successful sending of the test
frame will be indicated by a CYAN light signal.
d. Deep sleep entry
While transporting or storing the ACW-TCR, it is best to place it in its deep sleep mode to limit unnecessary energy
consumption.
From any operating mode (except fault mode), bring a magnet near the diamond marking on the box for 6 seconds.
During these six seconds, the LED of the product will flash in the colour corresponding to the operating mode then the
end of the sequence will be indicated by a WHITE fade acknowledging that the product has been put on standby. The
magnet can therefore be removed.
e. Radio module activity
Any sending of a radio frame is indicated by three brief GREEN flashes of the LED.

13
ATIM_ACW-TCR_UG_EN_V1.0
f. Threshold exceeded
When thresholds have been configured using the configurator and the measurement values exceed these thresholds,
the product LED emits a periodic ORANGE flash to notify it.
g. Anti-fraud system
A mechanism (push button) is present on the product to notify any opening of the case during normal operation.
Normally, the box exerts pressure on the button. As soon as the back cover is removed, the button is released,
triggering an alert. A light signal indicates that the opening of the case has been considered.
In addition, if the module is connected to a network, an alarm frame will be sent immediately when the box is opened
and then closed.
h. Substitution to the magnet
You can use the push button on the ACW-TCR card to perform the same actions as the magnet (activate or standby
the product, activate / deactivate Bluetooth).
To do this, open the box and press the push button twice at the same time. A white flash indicates that the button
now acts as the magnet (button pressed = magnet approached, refer to the chapters Product Start up, Sending a test
frame and Deep sleep setup above to know how to use the button).
WARNING: Once the operations are complete, press the button twice again to restore it to its main function. A
white flash indicates that the manipulation was successful.
i. Battery passivation
The ACW-TCR incorporates a battery depassivation feature, to limit the phenomenon of battery passivation during
prolonged phases of deep standby. This feature is automatically activated as soon as the product goes into its deep
sleep mode. The product will then wake up once a day to start the battery depassivation sequence, then the product
will automatically return to deep standby.

ACW configurator
a. Compatible configurator version
For a TCR with the following application software version
Use the version of ACW Configurator
Sigfox: V0.0.1
LoRaWAN: V0.0.1
V5.1.0 or greater
Download and install the configuration software setup “setupACW.exe” at:
https://www.atim.com/en/downloading/
When the ACW Configurator is launched, the waiting
window appears on the screen.
Click on "Help" at the top left of the window then on
"About" to display the version number of the ACW
configurator.
Pairing the ACW-TCR with the configurator can be done in two ways:
⚫Through USB: open the case of the ACW-TCR and connect it to a computer with a micro-USB cable.
⚫Through Bluetooth: make sure that Bluetooth is activated
Do not leave the product connected to the configurator (via USB or Bluetooth) unnecessarily, otherwise
the autonomy of the product will be seriously degraded.

ATIM_ACW-TCR_UG_EN_V1.0
b. Configuration du ACW-TCR
Emission period and samples in the frame
The transmission period (1) corresponds to the time interval between each sending of a measurement frame. This
period can be configured from 10 min to 255 h and its default value is 1 hour.
In addition, it is possible to configure the number of samples in a frame (2). Thus, several measurements will be carried
out before the sending of the frame which will contain all these measurements.
For example, with a period of 12 minutes and several samples of 4, a measurement will be made every 3 minutes and
the 4 samples will be sent in a single frame every 12 minutes.
Finally, it is possible to apply a redundancy of the data (3), which means that samples having been sent in the frame
n-1, n-2 or n-3 could be sent again in the frame n to the continuation of the new measurement samples (the most
recent sample first in the frame and the least recent last).
For example, for a history depth of 3, data from the last 2 frames will be sent, in addition to the new data, in the next
frame.
Keep alive frame period
A life frame can be sent periodically (4). This frame will contain the supply voltage of the product.
The value of this period can be configured from 1 hour to 1 month. By default, the value is set to 4 days.

Frame timestamp
It is possible to enable / disable the timestamp in all radio frames (5).
WARNING: This option when activated monopolizes 4 bytes in the frame which cannot be used for useful data.
Product’s clock
Each time you connect to the configurator, the product clock is updated (based on the computer clock) and displayed
(6). In addition, an offset in seconds can be applied if needed.
Versions of the product
When connecting to the product, the configurator retrieves all the software versions of the product (product software
and radio module software) as well as the network identifier (7).
Sensor’s configuration
On ACW-TCR, only a single Temperature/Humidity can be connected. However, the interesting part of the ACW-TCR
lie in the possibility to activate a virtual probe which apply an inertial coefficient to the measurement returned by the
physical probe.
In deep, the virtual probe’s values are calculated by averaging the x last values from the physical probe.
According to this, the parameters are (8):
-Enabling and disabling both virtual and physical probes.
-The value of the inertial coefficient representing how many physical probe’s measurement are considered to
calculate the value of the virtual probe.
Example
If inertial coefficient is equal to 5, the virtual probe value will be the average of the last 5 physical probe’s
measurements.
In addition, a threshold detection can be activated on each probe to detect a high or low threshold according to a
configurable hysteresis and duration of overrun. When a measurement reaches a threshold, a radio frame will be sent
(see the Alert Frame chapter for details on the frame format).
Validation the configuration
After having filled all the configuration parameters, it is imperative to click on the button "Apply to ACW" to send the
configuration to the product (9).
It is also possible at any time to read the current configuration of the product which will update the parameters on
the configurator or to reset the default configuration of the product.

Frame specific data
We can differentiate three types of frames:
⚫Classic frame; New generation: Very similar to the old frames, the difference is that you can activate the
timestamp. These are for example the life frame, the error frame, the response to configuration frames, ...
These last frames are common to all ACWs but, it is also possible to have other independent frames for each
ACWs.
⚫Measuring frame; New generation: These frames consist of samples of the different values of each of the
channels that an ACW can read. Beforehand, the number of samples and the depth of the history will be
inserted in the header.
Notes: The number of samples and the depth of the history are in common for all the
channels of the frame.
⚫Alert frame (threshold crossing); New generation: These frames combine a conventional frame and a
measurement frame. They consist of a header warning that a threshold has been exceeded, followed by
samples of each of the channels for which a threshold has been exceeded.
