Expanding the dialog to show additional options
When selected, the firmware download dialog box will automatically close
after the program is completed.
When only one drive is connected to the host, the drive address is not
⚫
required.
Before activating the firmware download process, the software attempts to
communicate with the drive that is communicating with the host. Therefore,
if the drive responds to serial communication, the firmware download
process will continue.
When multiple drives are connected to the host in daisy chain, the
⚫
drive address must be specified.
After specifying the drive address, the software will be started by sending
the command \\, which will stop all drives connected to the selected serial
port from responding to serial communications. It then issues the
command \nn, instructing only the drive with address with nn to respond.
The COM port of the host to which the drive is connected. Make sure this
COM port is not in use by any other application.
The baud rate must be set to 115200.
Ember is a process for burning new firmware on the flash memory of the
drive.
Software Usually using default software options.
⚫
Hardware Using this option if the firmware loading process is
⚫
interrupted and you cannot establish communication with the drive.
The firmware update process uses optimization methods to improve
performance. In rare cases, this optimization may cause the program to fail.
In this case, please disable optimization and restart the firmware update.
When selected, the firmware update process will store all user parameters in
memory before downloading the firmware, and
restore the parameters after the update. This option can be disabled.
This option is not available if the host and the drive are not communicating.
Note: Regardless of the setting of this option, it is strongly recommended
that you use the Save to Backup option in the Backup and Restore screen
to preserve existing drive parameters before updating firmware.
