Firmware Updates
Using the Update Wizard
The control panel can be used to download firmware
updates to the DM units. The Update Wizard guides you
through the steps of the update process. Since a failed
firmware update can leave the DM in an unusable state,
it is important to follow the instructions in the Update
Wizard exactly. This procedure uses a DM1624F; how-
ever, it applies to all units in the DM series.
NOTE: The update process is possible only using
a USB connection.
Firmware updates are distributed as a file whose name
follows the pattern “DM1624F-vX_X_X.update”, where
the “X_X_X” is a placeholder for a firmware version
number. For example a firmware update for version
number “1.1.12” would have the filename “DM1624F-
v1_1_12.update”. The dots normally used to separate
the three parts of the version number are replaced with
underscores in the filename for clarity.
Before starting make sure that the proper update file is
on hand. Connect the DM1624F to a computer sys-
tem with a USB cable. Apply power to the DM1624F
and start the control panel software on the computer
system.
