APPENDIX 2 - FIRMWARE UPGRADES FOR
BASIC EXTENDER INSTALLATIONS
Extender systems (or individual DDX-USR units) can be upgraded using a USB stick if
required. This is carried out as follows:
1
Connect the DDX-USR to a compatible display and keyboard; optionally connect to a
DDX-CAM module using a CATx data cable to upgrade it at the same time.
2
On the DDX-USR unit, insert a FAT32-formatted USB stick containing the extender
firmware upgrade file into one of the front USB ports.
Note: The extender firmware
upgrade file must be in the root folder.
3
Apply power to the DDX-USR unit and DDX-CAM modules.
IMPORTANT: Ensure power remains uninterrupted throughout the upgrade process.
4 Press-and-hold the recessed reset button for ten seconds until the PWR indicator
begins to flash quickly, then release the reset button.
5
When prompted, type in the name of the extender firmware upgrade file and press
Enter.
6
Type Y or N as appropriate, when asked if an attached (DDX-CAM) transmitter unit
should also be upgraded.
7
The display will show the upgrade progress and confirmation message.
8
If successful the DDX-USR and DDX-CAM modules will automatically be rebooted
and the USB stick can be removed.
