Flash Memory Management

The CodeWriter 4500 Series printer provides the user with a dedicated 32k area of
flash memory to store applications or label formats. To use this area the user must
understand how to access the area and copy the application to the printer. The
following information is provided to assist the user in understanding the function of
the flash memory on this printer and how they can interact with it.
The firmware contains several front panel button press combinations that can
influence the power-up initialization of the printer.

High Speed Firmware Update Download Mode

Hold down the
ONLINE
PAUSE and buttons while turning on power. Do not
release until the printer displays the “>> Flash Boot <<” message.
This places the printer into the high speed firmware update download mode.
In this mode, the printer will accept firmware downloads at strictly 115,200
baud. Firmware downloads require a special application on the host computer
which Datasouth provides along with firmware updates. Firmware downloads
cannot be performed by operators using terminal emulation or other generic
host applications.
Although very unlikely, the potential exists for operators to corrupt any
existing firmware within the printer by accessing the firmware update
communications mode using improper host software. If this occurs, the printer
will require a new firmware download to correct the problem.

Auto-Baud Firmware Update Download Mode

Hold down the
ONLINE
PAUSE and
ITEM
FEED buttons while turning on power. Do not
release until the firmware displays the “>> Flash Boot <<” message.
Exactly the same as the High Speed Firmware Download Mode, except the
firmware will perform an autobaud operation when initially establishing
communication with the download application on the host computer. This
mode will only autobaud to between 2,400 and 57,600 baud. In order to
perform a high speed 115,200 baud download, the operator must select the
high speed download mode.
