Housing
a. Fastening
The ACW-WL modem is mounted on a flat wall using the 4 mounting holes available at
each end of the box. For best results, it is recommended to install the box at a distance
from any metal object, e.g. avoid mounting it on a metal pole. As the antenna is integrated
in the box, it must be mounted vertically in the right direction on a vertical support or fixed
to a wall. The cable and/or the electrodes (2 screws) must always be downwards.
Identification
The product identifier is visible on the external label on the back of the product, inside on the electronic board and in
the status bar of the configuration software.
For LoRaWAN modems the communication keys are automatically given by the network (pairing by "Over The Air
Activation", or OTAA).
Each product of ATIM's ACW range has a QR Code label visible on the side of the product.
This QR code can be easily read with any 2D barcode reading application on smartphone.
