Prelude
This user guide describes the ATIM ACW-MR products functionalities. It explains operating, configuration and
installation modes in functions of different use cases.
ACW-MR Product line
ACW-MR product line regroups different types of radio equipment which allow pulse metering, bang-bang control and
fraud detection.
Each devices of this product line are available in LoRaWAN and Sigfox version and are delivered with removable
batteries. They are can be parametrized through intern switches or via downlink frames on the network (exclusively
on LoRaWAN version).
ACW-MR4
The ACW-MR4 is a sensor used for remote metering monitoring (gas, water, electricity,
pluviometer meters…) or for remote bang-bang equipment control (eg: starting up/shutting
down, opening/closing...).
This sensor can be connected up to 4 independent equipment when they are close enough,
allowing devices and network plans savings.
The ACW-MR4 is delivered with two Lithium 3.6V removable batteries packs with a total capacity
of 14400 mAh.
CAPT-OPT2 & CAPT-MECA
In addition to the ACW-MR4, there are 2 metering
sensors options: an integrated optical sensor, this
plug and play device monitors remotely the
consumption of an LED optical electrical meter (eg:
Linky meters, PME-PMI meters) or an integrated
mechanical sensor which traduces the rotation of
the meter index into pulses and then to energy
consumption. It is delivered and pre-set to
memorize the consumption index every 10
minutes and send the last 6 every hour.

Operating
Operating modes
The operating of the ACW-MR4 is divided between different modes:
-Operating 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, see Factory settings).
-Deep sleeping mode: this standby mode mainly allows you to put the product to sleep from the time it is put
into service until it is installed on site. In this mode no measurement or radio communication functions are
possible.
-Configuration 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).
-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:
•Measurement function error
•Low Battery (less than 15% of the maximum battery level)
•Empty Battery (less than x% of the maximum battery level)
•Radio module error
•Automated tests errors
•Casing opening
•Application error
-The entry in the Fault mode is shown by a RED LED blinking 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 Frames format for error codes). In addition, the product will emit an audible
and 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 colors depending on the mode:
for operating mode
for configuration mode
for deep sleep mode
for fault mode

16
ATIM_ACW-MR4_UG_EN_V0.9.docx
Product start-up
In most cases, the ACW-MR4 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 six seconds, the product led must flash in WHITE then in GREEN at the end of the six
seconds to indicate that the product is on the way.
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 an audible signal and a light signal depending on the quality of
the network:
•GREEN led signal: good network quality
•YELLOW led signal: medium network quality
•ORANGE led signal: bad network quality
•WHITE led signal: no information on the network quality
The module will then enter its operating mode and start feeding information back to the network according to the
configuration.
In the event of a connection failure (in LoRa only), the ACW will return to its fault mode because no radio transmission
can be carried out.
WARNING: For information on the quality of the Sigfox or LoRaWAN network, it is necessary to provision a
Downlink. It is this one which will make it possible to decide on 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 chapter Classic frame
(frame type 0x02). If a Downlink is provisioned, the information on network quality will then be relayed by the ACW
(light and sound signal). If no Downlink is provisioned, the ACW will always display a WHITE light signal.
Test frame
When the product is in its operating mode (and only in this mode), it is possible to send a test frame including a
measurement sample (which avoids waiting for the next measurement frame).
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.
Deep sleep
When transporting or storing the ACW-MR4, it is best to place it in its deep standby 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.

17
ATIM_ACW-MR4_UG_EN_V0.9.docx
During these six seconds, the product led will flash in the color 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.
Radio module activity
Any sending of a radio frame is indicated by three brief GREEN flashes of the LED.
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.
Anti-fraud system
A mechanism (push button) is present on the product to notify any opening of the case during normal operation.
In normal times, the box presses the button. As soon as the back cover is removed, the button is released, triggering
the fault mode of the ACW-MR4. An audible and light signal indicates that theopening of the case has been considered.
In addition, if the module is connected to a network, an error frame will be sent every 24 hours until its next restart.
Substitution to the magnet
You can use the push button on the ACW-MR4 card to perform the same actions as the magnet (activate or deactivate
the product, activate / deactivate Bluetooth).
To do this, open the case and exert two simultaneous presses on the push button. An audible signal as well as a white
flashing indicates that the button now acts as the magnet (button pressed = magnet approached, refer to Product
commissioning, Test frame, Deep sleep above to find out how to use the button).
WARNING: Once the manipulations have been completed, press the button again two times to restore it to its main
function. An audible signal and a white flashing indicate that the manipulation has been successful.
Battery passivation
The ACW-MR4 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 be awakened once a day to start the battery depassivation sequence, then the
product will return to deep standby by itself.

ACW configurator
Compatible configurator version
For an MR4 with the following application software version:
Use the version of ACW Configurator:
Sigfox: V0.0.1
LoRaWAN: V0.0.1
V5.0.1
Download and install the configuration software setup ’setupACW.exe‘ at:
https://www.atim.com/en/support-2/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-MR4 with the configurator can be done in two ways:
⚫By USB: open the case of the ACW-MR4 and connect it to a computer with a micro-USB cable.
⚫By 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.

19
ATIM_ACW-MR4_UG_EN_V0.9.docx
ACW-MR4 setup
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 a number of 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, the data of 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 raise 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 deactivate / activate the time stamping of all radio frames (5)
WARNING: This option when activated monopolizes 4 bytes in the frame which cannot be used for useful data.
Product clock
If the time stamping function is activated, it is essential to configure the internal clock of the product from the
configurator, which will retrieve the system clock from the computer to apply it to the product (6).
Product versions
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).
Inputs configuration
On the ACW-MR4, the 4 inputs can be configured individually (8). So, for each entry you can configure:
-Input function: front detection, metering or disabling
-Type of line draw: to ground or towards power supply
-Trigger front: rising, falling edge or both.
In addition, it is possible to configure an anti-bounce time which corresponds to the wait following a level change
before taking it into account (bounce time).
Finally, when the input is configured for edge detection, and only in this mode, its current state is indicated on the
right (under "Active level").
Metering thresholds setup
In the case where an input is configured as a counter, it is possible to activate a threshold detection function allowing
to alert by a radio frame that the counter has exceeded a certain value (9).
Meters overview
When an input is configured as a counter, it is then possible to have a real-time display of the value of the counter and
of the triggering input (10).
Setup validation
After having filled in all the configuration parameters, it is essential to click on the "Apply to ACW" button to send the
configuration to the product (11).
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.
