Loading firmware using the USB A Host
1.
Create a folder on the flash drive at the root level named TallyDascom.
2.
Inside this folder create a folder named Firmware.
3.
Copy the firmware file (obtained, for example, from the manufacturers web site) in
the Firmware folder.
4.
After the printer has fully booted and is displaying a ready state, insert the USB
flash drive in the printer’s USB A connector.
5.
The printer reads the file in the
TallyDascom
\Firmware folder, and determines if it
contains a firmware upgrade.
6.
If a firmware upgrade is needed, the printer reads the contents of the firmware file,
then re-programs the printer flash memory, and finally reboots. At this time, the
new firmware is loaded and executed in the printer.
NOTES
: The printer will only read the contents of the usb flash drive if it is
inserted after the printer is ready.
Do not modify the firmware file name as distributed by the manufacturer. The
printer uses the filename to know whether the firmware image contained in the
file represents an upgrade. Changing the filename will result in unexpected
results.
To get consistent results, there should be only one file in the
TallyDas-
com
\Firmware folder.
If the file will not load from the usb flash drive, it may be incompatible or it may
contain firmware that is earlier than what is currently running. Please verify
that the firmware file contained in the folder is proper for the printer. If it still
will not load, use the administrator configuring tool to load the firmware.
