Important upgrade notice for DDF7000 series processors shipped prior to May 26, 2016
When two or more DDF700x processors are connected to a local network and are powered on at exactly the same time there is a good possibility that the processors will hang up in the boot loader and not run the main direction finding firmware. A new boot loader (version 1.3) and MPT Flash (version 1.3) program are available that fixes this problem. If you are using or planning to use multiple DDF700x processors on the same network and you will be powering them up at the same time then you will need to use the MPT Flash program to reprogram the boot loader. If you are not using multiple DDF700x processors on the same network we do not recommend upgrading the firmware.
Please download the instructions and read them carefully before proceeding. Right click on DDF7000 Boot Loader below and select Save Target As or Save Link As to download version 1.3 of the bootloader. You must also download the latest version of the MPT User Interface and install it.
Legacy Product Upgrades
Firmware upgrades for Series 5900, 6000 and 6100 DF processors may be downloaded at no charge by our customers. The firmware programs are Intel HEX format which can be loaded into a 27C512 EPROM. The EPROM must be at least 120 nsec and should preferably be 90 nsec. You will need an EPROM programmer and, if you plan to use the existing EPROM, an EPROM eraser.
Series 5900 Upgrades
The older version of the Series 5900 was the DDF5911. It can be identified by the 15 pin female connector used on the front panel for the RF Summer control cable. The current version of the Series 5900 is the DDF5931 and it uses a 15 pin male connector for connection to its (different) RF summer.
The firmware used in the processor can be upgraded by simply replacing or reprogramming the EPROM. The version displayed in the remote display (DDF5921) when the system is first powered up is the firmware revision of the remote display itself, which can not be upgraded.
To determine the version of firmware in your DDF5911, connect the unit to a PC, run Hyperterm at 4800 8N1, and issue serial command number 32 (identify software). You can also remove the bottom cover and note the marking on the EPROM label. Locate the firmware revision in the table below to determine whether to upgrade.

Check the crystal frequency used in your DDF5911 by removing the bottom cover. Look for the crystal that is closest to the microprocessor (U105). It will be either 9.216 or 9.830 MHz.
The firmware used in the processor can be upgraded by simply replacing or reprogramming the EPROM. The version displayed in the remote display (DDF5921) when the system is first powered up is the firmware revision of the remote display itself, which cannot be upgraded.
To determine the version of firmware in your DDF5931, connect the unit to a PC, run Hyperterm at 4800 8N1, and issue serial command number 32 (identify software). You can also remove the bottom cover and note the marking on the EPROM label. Locate the firmware revision in the table below to determine whether to upgrade.

Check the crystal frequency used in your DDF5931 by removing the bottom cover. Look for the crystal near the microprocessor (U105). It will be either 9.216 or 9.830 MHz.
Series 6000 and 6100 Upgrades
For a nominal charge, we will upgrade the firmware and retest the processor for you. This is generally best as accessing the EPROM on these units is more difficult, and it is easy to misidentify the model number and revision of the hardware. To upgrade the firmware yourself, follow the directions below:
To determine whether you want to upgrade, locate the firmware version of your current model in the following table. This table lists all of the revisions which have been shipped and the changes that have been made. To determine which version you have in your direction finder, note the first display shown in the bearing window following power turn-on. The version is displayed as X.XX in the bearing window with a 1 displayed in the S-meter window.

To obtain a firmware upgrade, you need to identify the hardware version of your direction finder. The basic model number (DDF6000, DDF6100, DDF6001 or DDF6002) is marked on the front panel. To determine the revision level of the unit, remove the top cover and refer to the descriptions and photos shown on the web page DDF6xxx Identification.
The latest version EPROM program may be obtained by downloading the HEX file listed in the table.
