Communication
Error
One or more hubs
is not
communicating
with the access
point.
•
To restore communication between the hub
and access point, click
Actions > Refresh.
•
If the error message remains, select the hubs
that are not working, remove them from the
network, and then add them back into the
network.
The batteries in
the network hubs
run down during
class time,
resulting in dead
or low batteries.
•
Make sure the network hubs are recharged
overnight at least every other night. If your
system is used heavily during the day,
recharge the batteries every night.
•
Normally, the network hubs’ rechargable
batteries can be recharged and used for up to
two years (Type 1) or three years (Type 2). If
you charge a battery overnight and the LED
on the network hub still blinks red or amber,
contact Texas Instruments for help.

Do not attempt to configure more than one
classroom network at the same time.
•
Remove the network connector from hubs
that you do not want to add to your network.
•
Compare the hub numbers listed in the
Network Manager window with the numbers
stamped on the backs of the hubs themselves.
Highlight and remove any hubs in the list that
should not be part of your network.
Data is received
by some
calculators, but
not all.
•
Check the cable connection between the
calculators and the network connector.
•
Make sure all of the calculators have the
latest operating system from Texas
Instruments installed.
•
Make sure the calculator’s RAM is not
completely full.
•
Make sure an alternate operating system,
such as Mirage, is not installed. If found,
remove it from the calculator.
