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.

Restore erased or faulty Firmware

You can upload the firmware to the DSP at any time via the network or USB interface using the firmware upload 
function of the network manager.

Click in the network manager

„Tools“ → „Enable Update“

As soon as the DSP has been recognized on the computer, the DSP control software will locate the device. It is 
displayed in the network manager as "No Name".

In order to upload the software just click the orange button.
After confirming the upcoming message with OK, the software carries out the update.

After a few seconds, your DSP is ready for use again and you can start configuring or adding the presets.

4.4

Restore deleted / faulty bootloader of the network chip

If the DSP can no longer be reached via the network interface, the cause may be a deleted bootloader in the 
network chip. You can upload it again within a few seconds, and your DSP will then be found again via the network 
manager of the DSP control software.

Switch off your PowerPac 4003DSP.

Connect to the DSP-Control Software.

Open the DSP Control Software and choose in the menue

„Tools“

the function 

„Enable Update“

Switch on your PowerPac 4003DSP. Please be aware you have just some few seconds...

Quickly push in the network manager in the line „Start up“ righthand the orange button and confirm the 
upcoming advise window with „OK“.

The firmware-uploader opens and runs the upload of the bootloader (1).

Note: while the firmware uploader is working, you can tell from (1) that the network chip is being updated and (2) that the DSP firmware 

is being uploaded.
