Firmware update process
After you have established the network / USB connection, start the PL-Audio DSP-Control software on your
computer. The network manager now opens, in which the connected PL-Audio DSPs in the network or at the USB
ports are listed.
Now click on "Tools" in the menu bar of the network manager and select „Enable Update“
If firmware version 3.8.7 or higher is installed on your DSP, you can carry out an update directly from the "USER"
level. After click on the orange button on the right in the window, the software will carry out the update after
confirming the message window with OK.
If an older firmware version such as 3.1.5 is installed on your DSP, no user rights are available for the update. The
update button is gray in this case. To do this, you must first open the control window with the start button (green
arrow) and then click on
Hardware → Enter Password
in the menu bar at the top of the control window.
Enter the password "Ad_min" here. After you have entered the correct password, you will find the message
(administrator) in the status bar. You can now close the control window again.
The update button is now orange in the network manager. Press this orange button to start the update.
After confirming the message window with OK, the software carries out the update. The firmware update takes
about 60 seconds, depending on the interface speed.
IMPORTANT NOTICE: Please do not interrupt the power or data connection to the device during the update
process. This leads to the deletion of the firmware on the DSP!
4.3
Erased / faulty firmware
If the computer system is interrupted, crashed or hung up during the update process, first close the application.
Then switch off the PowerPac 4003 DSP.
Check the network or USB connection and restart the PL-Audio software.
Now switch the PowerPac 4003 DSP back on. The fan will now start up briefly. If the display is dark and does not
work, the DSP does not have any firmware.
