Installation
The installation of the
IWM-LR3
module is allowed on the GMDM-I, GMB-RP-I and GMB-I meters only.
It is recommended to install the
IWM-LR3
module away from metal objects or any potential radio
shielding, in a place protected from tampering.
Provision the network server in which you want to integrate the sensor (AppEUI) and provide the
application server with the unique DevEUI and AppKey keys. The installer has the task of checking the
propagation conditions of the radio signal during installation.
Commissioning
Make sure that you have respected the installation conditions described above and that the module
is positioned within the operating range of the LoRa gateway installed.
Remove the aluminum sticker applied on the bottom of the module to initialize it and send joining
requests to the desired network server. Now connect the module on the meter as shown in the
picture.
It is necessary to pair the inductive index of the meter beneath the inductive sensor placed on the
plate of the module. With one hand, keep the meter steady, with the other hand press then carefully
the module and turn it in a counter-clockwise direction to lock it to the meter.
Configuration by using Android App + NFC Device (for ABP mode or parameter modification):
to initialize the configuration process, place the NFC antenna of the android device near the module
as shown in the picture. For the complete configuration instructions, please refer to the app manual.
Check on the reading software/web application the correct data collection and check that no alarm
is active. To avoid possible frauds on the module, it is recommended to tighten the mounting screw
supplied and apply the adhesive seal.
