K Series Service Manual
3.2 Firmware programming instructions
Warning
If the instructions are not followed carefully, there is a possibility that the amplifier inside the loudspeaker will stop work-
ing. Because House of K loudspeakers use DSP technology, all audio signals are routed through the DSP controller. If the
firmware is not programmed into the DSP controller correctly, then the amplifier will fail to pass audio. While performing a
firmware update, never plug the ribbon cable into the programming header with the amplifier turned on.
Equipment needed
• Total Phase Aardvark I2C Host Adapter, TP240141
• Ribbon cable adapter, 6 pin to 10 pin (not needed for some older K models)
• USB cable, A-type to B-type (included with Aardvark)
• Computer with Windows XP, Vista, or 7 operating system (32 bit or 64 bit okay)
Software needed
• Total Phase USB driver setup file: TotalPhaseUSB-v2.10.exe
• K Programmer Utility (32 bit or 64 bit)
• HEX file which contains specific loudspeaker firmware
Installing the Total Phase Aardvark USB Drivers
This step must be performed before any programming takes place. The installation file for
the USB drivers will work on Windows XP, Vista, 7 (32 bit and 64 bit), and 8.
1. Disconnect the Aardvark if you’ve already connected it.
2. Open the installer file named TotalPhaseUSB-v2.10.exe.
Important Note: There is a known bug in the installer that affects Windows Vista
only. You must run the installer in a different mode. Right-click on the install file Total-
PhaseUSB-v2.10.exe and click on Properties. Click the Compatibility tab and mark the
box titled “Run Compatibility mode for Windows XP (Service Pack 3)”. Click OK to save the
changes.
3. Mark the box titled “Install USB Drivers” and continue with the installation utility until
complete.
4. Connect the Aardvark to the computer with the USB cable.
5. The Total Phase USB drivers will install automatically. You may skip any
Windows Update notification as you do not want Windows to look for USB
drivers via the Internet. Windows will let you know that the drivers installed
correctly with a pop-up window.
Note: If you want to check that the USB drivers installed correctly, go to the
Device Manager under the Control Panel menu and look for “Total Phase
Aardvark I2C/SPI Host Adapter” under Universal Serial Bus controllers.
