ProfiLux 3: What to do in the case a firmware update failed

[aqua_digital]

Then you do not have to go rooting around to find a serial to USB adapter then. Please read the section on firmware update.

I

• Download the flasher tool „Flash-FR.zip“ from http://support.aquariumcomputer.com/...oad.php?did=48 and unzip into a folder you find afterwards easily (no installation neccessary)
• Download the firmware for the Profilux and unzip into a folder you find afterwards easily.
• Unplug the ProfiLux from power
• Open the ProfiLux casing as shown in the manual
• Set a jumper to the pins of JP1
• Connect the USB cable to the build-in port of the ProfiLux und an available USB port of your computer
• Start the windows device manager and open the selector for "COM and LPT". There you can see the available COM ports of your PC.
• Plug in the power cord of the Profilux again. Now there will be a new port „USB Serial Port“ – this is the port of the pro ProfiLux. I f there is a yellow exclamation mark, you have to install the USB driver first.
• Start „flash.exe“ from the folder you copy it to.
• Change/check the settings as follows (it´s important to have exact this settings):
• Target Microcontroller: "MB91F467D"
• Crystal Frequency: “4MHz“
• Press „Open“ and navigate to the firmware file and select it. The firmware name has to start with „ProfiLux3_“ and has the extension „.mhx“, for example ProfiLux3_V515_GER_ENG.mhx
• If there is only a „.zip“ file, you have to unpack it first
• Select the COM port at „Set Environment“.
• Now press "full operation", there will be a download window.
• Press the reset button now to start the download. If it won´t start, check the port setting - it may be the wrong.
• If the download is finished, confirm the message with OK and close the flash program.
• After that, unplug the profilux, remove the jumper from JP1 (it´s enough to put the jumper only to one pin).
• Now the ProfiLux should strart normally if you plug in power. Close the casing now!

This is a 5 minute procedure and i actually prefer using it on all updates as its faster.

If you follow the update path correctly however you should never have to use this process anyway.
