TROUBLESHOOTING
Once you apply the steps described above, if you still cannot see
the Transmitter on your VC check the following items:
1. Blue LED
– The Blue LED on the Transmitter blinks every time
it transmits data. If the Blue LED is solid on it then means that
it’s trying to connect and transmit data to the access point with
no success.
2. Java Runtime Environment (JRE)
– Make sure that the
Java Runtime Environment (JRE) is running on the PC on
which the VC is installed. If the Java Runtime is not installed
on the computer the VC will not display readings from the
Transmitters. Should be 32-bit Java version 1.6 or higher.
3. Wireless Connection –
If you plan to connect on a wireless
LAN make sure that the wireless connection on your computer on
which the VC is installed is linked to the correct access point. You
may want to connect to the same access point to which the
Transmitter is connected. You can verify that by looking at the
Wireless Connection Manager on your computer.
4. Wired LAN
– If your computer is on a wired LAN on which
the correct access point is also connected, make sure that
you can reach the access point from your computer. This
can be accomplished by “pinging” the IP address of the
access point.
5. Firewall
– Make sure that the firewall is off or the exceptions are
added properly.
6. Back to AD-HOC Mode
– If you cannot find anything wrong
with your computer wireless connection and the access point,
then there is a chance that the Transmitter was not configured
correctly. To reconfigure the Transmitter you must put the
Transmitter back into the AD-HOC mode. To do this, open the
case, slide the red Power button to the OFF position. Next, press
and hold the white Default button, slide the red Power switch
back to the ON position, and release the white button once the
blue LED comes up solid. You can now follow from
Step 3.4
of
the Transmitter’s Initial Configuration section.
7. Access Point/Wireless Router
– In general, the latest/newest
access Points are better than older ones. Also, check to see if
your access point has the latest firmware installed.

b)
Channel
– This is the Wi-Fi channel on which the
access point is accepts connections. If not sure what
channel to use, simply select Auto.
c)
Authentication
– This is the security method which the
access point is using for connections. Choose the
desired security based on the present access point settings.
Use WPA2-PSK for the most secure
connection. No security can be used to
conserve battery power. WPA2-PSK
Enterprise is not supported
d)
Passphrase
– If the authentication is WPA2-PSK, then
enter a passphrase here.
• Passphrase restricted characters include
“ ;
• The minimum characters that can be used for
Passphrase/WPA2 is 8, maximum is 63.
e)
Default Key
– This is the password if authentication is
WEP-128.
• WEP KEY can only use the following characters:
a b c d e f 0 1 2 3 4 5 6 7 8 9
.
• WEP KEY must be a length of 26 characters.
f)
DHCP
– Check this option if the Transmitter will receive
a Dynamic IP address from a DHCP server.
For initial configuration, it is recommended to
use DHCP for assigning IP Address to the
Transmitter. The IP address can be made
STATIC from the Virtual Coordinator after the
Transmitter starts communicating with it.
g)
IP Address
– Assign a STATIC IP address.
h)
Netmask
– Assign a subnet mask associated with the
STATIC IP address.
i)
Gateway Address
– This could be the IP address of
your access point or wireless router which the
Transmitter is associating with.
j)
Virtual Coordinator IP
– Assign the IP address of the
PC on which the VC is installed.
k)
Communication Protocol
– This is the protocol used
to communicate with the VC. Either TCP or UDP
protocol can be selected. UDP is default and uses less
battery power.
l)
Virtual Coordinator Port
– Readings from the sensor
(Transmitter) are sent to the VC using this port number.
Use the default UDP protocol and port
50002
unless
this port is already used on the VC. If TCP protocol is
used change this port number to 50006.
m)
Update Period
– Enter the Transmitter’s reading
transmission frequency in seconds.
n)
Save and Reboot
– Click “Save Changes”. Verify the
settings and then click “Reboot”. The webpage should
say that the Transmitter is rebooted.
If your Transmitter has a display, you should now be
able to see the sensor readings on the display.
The Transmitter stays in AD-HOC mode for a
few minutes and then goes to sleep to
conserve battery. So the step to put the device
into AD-HOC mode and to configure it using a
web page needs to be done together.
Also during this time, it is recommended to set the
“Update Period” to the default (10 seconds). Once the
Transmitter and the VC are communicating properly, the
“Update Period” can be changed to the desired value.
3.6. Getting the Readings
If the PC used to configure the Transmitter is the same as the
one running the VC, then change its IP address to the STATIC
IP address set for the VC. Start a new browser and enter
http://<IP address of PC running virtual coordinator>
If using a different PC, go to the PC running VC. Open up a web
browser and enter
http://<IP address of virtual coordinator>
Click the button that says readings. Enter the user name as
“
user
” and the password as “
12345678
”. You should be able to
see the readings.
