Product commissioning
Sensor connection
•If the LTE-M modem is supplied without a sensor, it can be connected to terminal block J2 on the circuit board.
•The sensor cable must first be inserted into the housing via the cable gland. Ensure that the cable runs to the
left of the terminal block, so as not to obstruct the passage of the battery when closing the housing.
•The cable gland is limited to a cable diameter of between 3 and 7mm.
•The modem's IP rating cannot be guaranteed if the sensor is not connected during manufacture.

Operating mode
If the magnet is held for more than 2 seconds on the location indicated by the QR code, the operating mode will change
according to the order defined below :
To find out the status of the product, simply pass a magnet briefly (<2 sec) over the above location, causing the LED to
light up in the corresponding color.
OFF mode : Modem off (default mode)
ON mode : The modem is activated and sends MQTT data frames
CONFIG mode : The modem connects to the configuration server
Magnet

ATIM_ACW-LTEM_UG_EN_V1.0
Once the mode has been changed, the modem processes an associated function. The LED then lights up continuously
while the function is being processed, for example :
•In ON mode, the modem starts sending a life frame before going into standby mode until the next frame is
sent (PSM for Power Sleep Mode).
•In CONFIG mode, the module connects to a server to download the latest configuration.
When the modem is processing one of these functions (green LED on), it is impossible to change modes.
Product commissioning
The modem is delivered in OFF mode. To switch it on, move the magnet until you see the GREEN LED (ON mode).
The modem then connects to the LTE-M network and the remote MQTT broker, retrieves any configuration (MQTT
subscribe) and sends a message (MQTT publish), before disconnecting and registering with PSM.
When the modem is properly connected, the LED flashes and gives an indication of the strength of the signal received
:
i. 4x times in GREEN if RSSI > -50dBm
ii. 4x times in YELLOW if RSSI is between -60dBm and -80dBm
iii. 4x times in ORANGE if RSSI < -60dBm
If a step is not carried out correctly, the LED flashes RED:
i. 3x if battery voltage is too low (below 3V)
ii. 4x times if network connection is impossible
iii. 5x times if the MQTT broker cannot be reached
iv. 6x times if the modem fails to reach PSM mode
In all four error cases, the start-up phase is considered incomplete, the modem automatically switches to OFF mode
and the RED LED remains lit until the magnet is used.
