Powering the TriCoder
The TriCoder can be powered by batteries or by the 5-volt power adapter
included with the unit. The TriCoder also has a programmable automatic
shutoff intended to conserve power. The following information explains how to
turn the TriCoder ON and OFF, the differences between battery power and wall
power, the two different batteries the TriCoder uses and how to change them.
The final section of this appendix provides details on both short and long term
storage of the TriCoder.
Turning the TriCoder ON and OFF
The ON/OFF key on the TriCoder keypad powers the TriCoder ON and
OFF whether the TriCoder is using battery power or accessing wall power
with the 5-volt power adapter.
To use the 5-volt power adapter, plug the power adapter into the wall outlet,
then into the TriCoder (the power jack is on the bottom of the TriCoder). Turn
the TriCoder on by pressing the ON/OFF key. Whether using batteries or wall
power, upon power up the TriCoder displays the following message:
DMA TRICODER Xxxxx Y
HIT ANY KEY_
Where:
X
is W for a TriCoder jumpered for Keyboard Interface or
R for a TriCoder jumpered for Serial Interface or
K for USB Keyboard upload or
H for USB High Speed upload
xxxx
is the firmware version (i.e. 2002) and
Y
is the board version (i.e. E)
Pressing a key on the TriCoder keypad takes you to the Mode Menu. If you
were in NON-PORTABLE mode when you turned OFF the TriCoder, it
will bring you back into NON-PORTABLE mode upon pressing a key.
Exit NON-PORTABLE mode by pressing the F1 key on the TriCoder
keypad. This will bring you to the beginning of the Mode Menu, displaying
the following prompt:
DATA COLLECTION?
KEY [YES/NO]?
Battery Power and Wall Power
For portable use, the TriCoder is usually operated using battery power.
Non-portable applications where the TriCoder is stationary typically use the
5-volt power adapter to utilize wall power and conserve batteries.
