Setup Tips and Troubleshooting
•
The Wi-Fi bridge Web interface has several configuration pages. Most settings can be
made on the
Express Setup
page. There are a large number of parameters which
can be adjusted. For the most part, if the parameter is not mentioned in these
instructions it does not need to be modified from the factory defaults. Exceptions
should only be made by knowledgeable IT personnel.
•
Don’t change the Ethernet settings (as opposed to wireless settings) on the Wi-Fi
bridge. These control the communications on the wired side. The IsoAir310P will
work properly with the factory default settings, but it may not work with any
modified settings.
•
To return to the factory default settings, hold the reset button down on the Wi-Fi
bridge for five seconds.
•
Configure the wireless router before setting up the IsoAir 310P units. Verify that the
wireless router can talk to a laptop/PC to check the configuration.
•
Most wireless routers use DHCP by default. Do not use DHCP, use fixed IP addresses.
Make sure that the fixed IP range is not being used as part of a range the router uses
for DHCP. The reason for fixed addresses is that the IP address is used to identify the
physical location of the sensor in the system.
•
Ensure that the exact same IP address is set in both the Wi-Fi bridge and the IsoAir
310P.
•
The gateway and DNS addresses are typically those of the wireless router.
•
Check the mirror image reflections of the Wi-Fi bridge status LEDs. Two green LEDs
means the Wi-Fi bridge is attached to the wireless network.
•
To turn off the Wi-Fi mode in the IsoAir 310P processor board, enter the following
three commands via HyperTerminal:
set inst wifi 0
set ip aaa.bbb.ccc.ddd
(if the IP address will be different for wired Ethernet.)

Getting Reliable Wireless Networking
•
Microwave ovens and wireless telephones that operate in the 2.4GHz and 5.0GHz
bands may cause interference if they are close to the system.
•
Try to provide a direct line of site between the IsoAir 310P and the wireless router (or
access point).
•
Mount the instrument and wireless router antenna as high as possible to obtain a
direct line of sight that is free of obstructions.
