UPGRADING THROUGH A DIRECT CONNECTION
Follow these instructions if you are connected to the DX4000 from a remote computer with a crossover cable. This computer also must have
access to upgrade files either on a network drive or a CD.
1. Connect the remote computer to the DX4000 with a crossover cable.
2. Turn off the DX4000 and disconnect the power cable.
3. While holding down the SCR Mode and Return buttons simultaneously, reconnect the power cable. A message resembling the following
appears.

4. Make a note of the IP address and subnet mask that are listed on the message, and then follow the instructions at Verifying Network
Connections on page 23 to verify that your remote computer is in the same subnet range as the DX4000.
5. From a remote computer, locate the upgrade files. These files can be located on a resource CD or on a network drive. The names of these
files might be different for each upgrade. The following file names are examples of what you should find:
• FirmwareUpgradeUtility.exe: This is the upgrade program that contains the software version number that you will install.
• DVR400ver.1.0.img: This is the actual updated firmware file that will be copied to the DX4000.
• DX4000RemoteAgent.exe: This is the installation program for the revised remote agent that you must install to communicate with
the upgraded DX4000. For instructions on updating the remote agent software, refer to Installing and Updating the Remote Agent
Application on page 26.
6. Double-click the upgrade program to start the installation process. The Image Downloader screen appears.
