Firmware and Model Upgrades

Firmware Updates

Occasionally it will be necessary for some users to update the TriCoder's
firmware to fix a bug or take advantage of new capabilities added to the
TriCoder. Previously, you had to actually replace the EEPROM chip inside the
TriCoder. With the DMA TriCoder models T54/LT54 and T64/LT64, the
TriCoder uses a Flash EEPROM and can be updated by downloading a file. The
latest firmware file can always be found on our website at:
http://www.barcodehq.com/download.html
file by email or on diskette.
How to Update
Once you have the new firmware file, be aware that you should first upload
all data files and clone the TriCoder to a computer file before starting a
firmware download. Data files and tables can be lost in firmware updates.
Sometimes the Setup and the Programs in the TriCoder can also be lost,
depending on the scope of the firmware change.
To initiate a firmware download to the TriCoder, run the TriCoder
EPROM Loader program (also available for download on our website at
http://www.barcodehq.com/download.html
that came with your TriCoder. Use the following instructions to prepare the
TriCoder for the firmware download:
1) Turn on the TriCoder.
2) Press and release the F2 Key.
3) Press the release the F1 Key.
Once you have started the firmware download, you should not interrupt the
process until it is complete. Depending on what point in the process the
download is interrupted, you could have trouble with the F2 F1 sequence
(see above). If you do, you will have to resort to the serial only failsafe
procedure described here:
1. Turn the TriCoder On, then immediately press and release the L key
Successful timing of this sequence produces nothing but a cursor in the
upper left hand corner of the TriCoder screen.
2.
Now press and release F2 followed by pressing and releasing F1
It should now be ready for a serial only firmware download.
If you have a Serial unit (T54/LT54), you can choose the download method
of serial or USB. If you have a Keyboard Wedge unit (T64/LT64), you will
have to use the USB firmware download (this requires the use of a USB
cable – our part # C21). You cannot do a USB firmware download unless
or call us and we can send you the
or on the TriCoder Utilities CD
B-1
