Wi-Fi Configuration
The following procedures should be used to configure the
Intelligent Equipment solution for Wi-Fi connectivity:
1. Mount and connect the wireless antenna per the
instructions included in document section, “Antenna
Installation”
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).
a.
The Wi-Fi settings of the M2M Gateway are
configured using HTML Interface pages in an
HTTP server.
b.
In order to access these pages, your computer
must be on the same subnet as the M2M Gateway,
which is shipped set to a default IP subnet mask
(
255 .255 .0 .0
) and IP address (
172 .31 .255 .1
). You
must change the computer’s network settings to
match the subnet (the Wi-Fi configuration process
is the same regardless of the operating system on
your computer).
c.
Navigate to your laptop’s Local Area Connection
settings screen and change the IP subnet mask to
255 .255 .0 .0
, and the IP address to be compatible
with the default M2M Gateway IP address
listed above (example:
172 .31 .255 .7
). For more
information on how to change your computer’s IP
settings, consult the Operating System’s “Help”
files.
d. Temporarily disable the wireless adapter(s) on the
computer, as these may prevent accessing the
HTML Interface pages.
3.
Open a web browser page and type,
172 .31 .255 .1
, and
then press enter.
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 13
).
4.
If the M2M Gateway will be using DHCP, skip to step 6.
If the M2M Gateway will be using a Static IP address, go
to step 5.
5. Click the ‘Network’ tab
a.
Under wlan0 Configuration (
Figure 14
), select
‘Static IP’ for Connection Type
b. Enter the IP, Subnet, and Gateway address
information
c. Under wlan0 DNS Servers enter the primary DNS
server and click ‘Add’
d. If a secondary DNS server address is to be
entered, enter it after the page has reloaded and
click ‘Add’ and enter the secondary address.
e. Click ‘Save’.
6. Click the ‘Wireless’ tab (
Figure 15 on page 14
)
a. Enter the ESSID of the network
b. If Wi-Fi security is enabled enter in Wi-Fi network
SSID and password and security type
7.
Click the ‘Save Changes’ button in the lower right corner
of the page.
8. Click the System tab, and then click the Reboot tab.
a. Click the ‘Yes, really reboot now’ button
b.
The gateway will automatically refresh after several
minutes.
9. Click the ‘Status’ tab
a.
Under ‘WLAN’, verify Wi-Fi signal strength (
Figure
16 on page 14
).
10.
Adjust antenna as necessary to establish a strong Wi-Fi
connection
a.
For reliable operation, signal level should be 60
dBm or lower and link quality power should be
50/70 or higher.
b. As the antenna is adjusted, be mindful that
signal strength is impacted by structures or other
antennas. As much as practically possible, make
efforts to avoid such interference while adjusting
the antenna.
11.
Once a strong Wi-Fi connection is obtained, close the
web browser, and disconnect the laptop and Ethernet
cable from the M2M Gateway.
12. Reconnect the Ethernet cable between the M2M
Gateway and the MicroTech III controller.
13.
Feed excess antenna cable into the control enclosure,
and then tighten waterproof grommet.
14. Add a bead of silicone around the perimeter of the
waterproof grommet penetration into the control
enclosure.
15.
On inside of enclosure, secure excess antenna cable
using zip ties.
