IsoAir 310P Aerosol Particle Sensor Operations Manual
Appendix C Wi-Fi Configuration
The basic settings on the wireless devices are configured for the IsoAir 310P. These are
essential for communication. In many installations, IT personnel will be involved with
the set up, and they may require more complex configuration settings and different or
more secure wireless security.
Here are the key parameters illustrated in
•
Network address will be required for each component in the system.
•
The network addresses must be on a different subnet than 192.168.2.x.
•
The wireless portion of the network will require at least an SSID, and some basic
security. In the example, the security is WPA-PSK. The Wi-Fi bridge supports a broad
swath of security modes such as WEP-64, WEP-128 and many others that are beyond
these basic instructions.
•
The IsoAir 310P instruments must be configured to communicate with the Wi-Fi
bridge in the enclosure, and the bridge and instrument must have matching
addresses.
on page C-3 shows the connection requirements from the IsoAir 310P to a
laptop that will be needed to configure communications. The following items will be
required for configuration:
•
Laptop with:
• USB to Serial Adapter if laptop does not have a serial port (PMS p/n 1000005556)
• HyperTerminal (Windows 7 does not include this) or a similar program
•
Cat-5 (Ethernet) Interface Cable
•
RJ-45 to RJ-45 Coupler (PMS p/n CO713 or 1000005733)
•
Serial Interface Cable (PMS p/n PMS-CD1995)
The IsoAir 310P electronics must be configured using a serial cable. The instrument
must be set to talk to the Wi-Fi bridge (via command
set inst wifi 1
), and it must be
configured with the desired IP address (via command
set ip
aaa.bbb.ccc.ddd
). This
address is used as a “virtual address” when communications are routed through the
Wi-Fi bridge.
The bridge itself must be configured to talk to the wireless network, and its IP address
must be set to the same address used on the instrument. Failure to do this will prevent
Facility Net from talking to the sensor.
The bridge has two IP addresses, a wired side address and a wireless side address. The
wired side address does not need to be changed from its factory defaults. The wireless
address must be set, and DHCP must be disabled on the wireless side. Furthermore, all
the wireless communication settings for 802.11b/g must be set as well.
