XTi, CDi, and DSi Firmware Update Instructions

Important: Any Crown CDi Series, DSi Series, and XTi Series amplifier manufactured before September 19, 2006 or having a serial number lower then 800129400 will require a firmware update. For instructions on updating these units please download this PDF or follow the directions below. For amplifiers built after this date, the firmware has already been loaded at the factory. The amplifier will communicate with System Architect without any need for any update. The manufacture date and serial number can be found on the rear of the unit.

XTi, CDi, and DSi Firmware Update Instructions for Pre September 19, 2006

Uninstall all other versions of the System Architect software and delete its file folder in the C:\Program Files\Harman Pro directory.

Install the build of System Architect on the CD or downloaded from the HiQnet web site.

Do not start System Architect at this moment.

Firmware upgrade instructions:

The first time you connect to a CDi, DSi or XTi amplifier via USB you will need to do a firmware upgrade.

Note: Firmware upgrade MUST be done one amp at a time using this method. Also, System Architect MUST be closed.

Copy the “CLoader” program to your desktop (included in the System Architect zip file).
Connect the USB cable to the amplifier and the computer.
After the Windows New Device acknowledgement open the CLoader program.
Select “Load File” and navigate to the location were the .hex firmware file is located for the amplifier:
- XTI11015.hex for XTi amplifiers
- DSI11015.hex for for DSi amplifiers
- CDI11015.hex for for CDi amplifiers
Select the file and then “Open”.
The amp front display panel will be displaying “--Wait--” and the channel 1 and channel 2 lights will be alternately flashing.
“Reboot” will be displayed next on the front of the amp and then it will display “DSP OFF” when completed.
After the amplifier reboots, the program will verify it has a valid serial number. If it does not, then it will assign one.
Perform steps 1-8 for each amp one at a time.
Close the CLoader program.

Note: Once firmware version 1.1.0.15 is installed in the amplifiers, the CLoader program will no longer be needed as all further installs can be done through the System Architect program.

First time use of System Architect you may need to activate USB:

If you have already performed the system Architect setup for USB you will not need to perform the following steps

Start System Architect in the lower left corner of System Architect will be a white button that should say “Network Active”. If it says “Network Inactive” than left click on it once to activate.
In a few seconds the amp should appear in the “Venue View Panel.
Select Tools|Options from the menu bar.
In the “Options” window select “Manage Network Connections” from “Network Settings”
Select “Add Connections”
In the “Network and Connections” window under “USB Devices” select the device with the Vendor ID (VID) of “4624”.
Select the “Add Connections” Button.
The new VID should be listed in the “USB Devices” window.

Device Addressing:

Each device will need to have its own independent HiQnet address. Currently the System Architect software will not auto address a USB device so the following steps will need to be performed on each amp one at a time.

Restart System Architect if it isn’t already running.
Connect an amplifier to the computer via the USB port.
After the device appears in the “Venue View” select Tools|Network Wizard from the menu bar.
Left click on the device to highlight it.
Select the “Configure” button.
In the “Configure Node” window give the amp a HiQnet address that is different than any other device in the network.
In a few seconds the device will appear in the “Network Wizard” with its new address.
Select the “Finish” button and restart the System Architect.
Device should be now seen in the Venue View with its new address.
