Page 3: Chapter 1. Introduction
Chapter 1. Introduction The WM-I3 is our 3rd generation low-power cellular pulse signal counter and data ® logger with a built-in cellular modem for smart water and gas metering. Automated water meter readings with customizable breakdowns, leak detection and prevention. Detection of water leakages to avoid flooding, non-revenue water for more accurate billing, optimization of operating costs, and improvement of water supply reliability. - Page 4 The device has an IP67 waterproof housing. The installation is easy, which is supported by operation LED lights to indicate proper functioning. Optionally, add-on boards can be attached to the mainboard to extend the capabilities (e.g. more inputs, M-Bus connection, etc). The modem has a special internal battery which provides energy for more than 5-10 years.
- Page 5 With the over the air (OTA) protocol, the device can be configured and the firmware can be updated remotely without the need to send experts to the field.

(9). 2.7 MBUS connection The WM-I3 device has an optional MBUS addon board (12) – order option – which can be connected to the J11 and J17 connectors by the right direction – as you can see on the next photo. - Page 12 Step #4: The J12 interface connection can be used for local configuration and firmware refresh by using the configuration cable (17). Step #5: The configuration cable’s (17) black connector must be placed to the WM-I3 mainboard’s J17 Connection interface (5-pins), according to the next photos. The black connector’s 1st pin is signed by a white mark, this side of the connector must be placed...
- Page 13 Step #7: Prepare for the configuration. Make a short on the Power ON pins (nr. 8). This will add battery power for the device. Then the modem will be starting its operation according to the configured settings. The device will be available to configure through the local serial connection. Step #8: Configure the device operation parameters on the local USB port by the WM- E Term software.

IMPORTANT! Note that the WM-I3 is operating from individual battery power source, which has a limited capacity and life time. Take care to the configuration and be fast as it is possible when you carry out the settings. When you have finished, remove the jumper from the J5 (marked by nr. - Page 17 #Step 2. Connect the USB dongle and download the driver from the manufacturer’s website: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers Choose the from the page and download the .ZIP CP210x Universal Windows Driver extension file. Extract compressed the file to a location on your computer’s hard drive. #Step 3.

Page 34: Firmware Update
3.15 Firmware update The Tools menu / Firmware update (LwM2M) feature works, therefore the firmware can be refreshed in LwM2M mode only. 1. Choose the the Tools menum Firmware update (LwM2M) item. Then the following window appears. Important! Note, that the LwM2M (Leshan) server must be running and connected to the network. - Page 35 4. The severity is the priority. 5. The maximum defer period means the delay of the firmware installation. 6. Change the settings and click on the Upload the parameters button. 7. Begin the firmware update by pushing the Start update button.
