The following procedures should be used to verify the cellular
signal strength for the Intelligent Equipment gateway.
1. Mount and connect the wireless antenna per the
instructions included in document section, Antenna
Installation on page 19.
2. Using a laptop computer and Ethernet cable, connect
to the “ETH” port of the M2M Gateway (you will need to
temporarily disconnect the Ethernet cable between the
M2M Gateway and the MicroTech III controller, to make
use of the “ETH” port on the M2M Gateway).
3. Navigate to your laptop’s Local Area Connection settings
screen and change the IP subnet mask to 255.255.0.0,
and set the IP address to be compatible with the default
M2M Gateway IP address of https://172.31.255.1
(example compatible address: 172.31.255.7). For
more information on how to change your computer’s IP
settings, consult the Operating System’s “Help” les.
4. Temporarily disable the wireless adapter(s) on the
computer, as these may prevent accessing the HTML
Interface page.
5. Open a web browser page and type,
https://172.31.255.1, then press enter.
NOTE: Your browser will likely notify you of a security risk
related to an unsigned security certicate. This is
expected, and does not indicate a gateway defect.
Simply click the ‘advanced’ menu link within the
browser, then accept the security exception.
a. When prompted, enter the User Name: “service”
b. Enter the unique password that was provided with
the Gateway hardware and press ENTER.
c. This opens the Gateway home page (Figure 85 on
page 40). The System Information section of the
Gateway home page will indicate that permission
is denied. This is expected, and does not inhibit
access to the functionalities required for properly
conguring the gateway.
6. Click the ‘Status’ tab
a. Select the ‘WWAN Modem’ tab
b. Under “Signal Quality, verify cellular signal strength
(Figure 86).
7. Adjust antenna as necessary to establish a strong
cellular connection
a. For reliable operation, signal quality and power
should both be in the good or excellent range.
b. As the antenna is adjusted, be mindful that
signal strength is impacted by structures or other
antennas. As much as practically possible, make
eorts to avoid such interference while adjusting
the antenna.
8. Once a strong cellular connection is obtained, close the
web browser, and disconnect the Ethernet cable between
the laptop and M2M Gateway.
9. Reconnect the Ethernet cable between the M2M
Gateway and the MicroTech III controller.
