Yaesu DMU-2000 update the flash programming

3/16/10

This procedure is used to update the flash programming for
the DMU-2000.

V4.21 or V5.11 version software is ONLY needed when the DMU-2000 is used with the New
FTdx5000 Transceiver. There is no change from V4.20 or V5.10 when used with the FT-2000/D
or FT-950 radios. If you already have System File [CF1] V0.08 or V0.09 you only need to install
the [CF2] V4.21 or V5.11 application file.

* This is the latest software and is compatible with all three FT-950, FT-2000/D and FTdx5000 series.

Check which version DMU software you have on your unit.

While holding the three buttons [GEN]＋[50]＋[ENT] turn the radio on. The software version will be
displayed in the lower right of the VFO-A window (FTdx5000 version will be shown in the Center
OLED display) for 5 seconds then the radio will start up in normal operation. Example: DMU-2000
software version 0511.

Software Version: 03xx, 04xx or

05xx.

If you already have software Ver.
0421 or 0511 it is not necessary to
update the DMU-2000 again.

Two types of computers are used in the DMU-2000. You must use the correct software for
your computer.

• If you have version 03xx or 04xx you must down load V0.08/V4.21. If you have V0421 you

have the latest software and do not need to update.

• If you have 05xx you must download V0.09/5.11. If you have V0511 you have the latest

software and do not need to update.

*You may also check the software level on the DMU boot up screen. Turn on the DMU front and rear

main power to boot the DMU processor. IF the YAESU boot up screen shows this small Phoenix BIOS

logo at the lower right of the screen, you have version 05xx and must download V0.09/5.10. If

the Phoenix logo is not shown, you have version 03xx or 04xx you must down load V0.08/V4.20.

SYSTEM (OS) APPLICATION
PC Ver.0.08 Ver.4.21 (03xx or 04xx)

PC

Ver.0.09 Ver.5.11 (05xx)

After you confirm the type of software it is very important that you only down load the correct
version from the Yaesu website.

CAUTION: Only down load the correct software for your version 0.08/4.21 or 0.09/5.11 for the DMU-

2000. Do not keep both versions on your computer.

Ver. 4.21 or 5.11 CPU implements improvements also includes all previous updates):

• ONLY Changes to support the New FTdx5000 Series Transceiver

Install the data file to PC

1. Down load the DMU-2000 data file [DMU-2000_V008_2-25-10.zip] or [DMU-2000_V009_2-

25-10.zip] from the following website:

http://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCatID=102&encProdID=66EA
91711DFB68C03DED4AD35153E12C&DivisionID=65&isArchived=0

2. Save the DMU-2000 data file [DMU-2000_2-25-10.zip] to the desktop on your computer.

3. Unzip and Extract the contents of [DMU-2000_2-25-10.zip] to the desktop of your computer.

4. You will find the CF1 and CF2 folders on your desktop.

The programmer and software are now stored on your computer on the desktop. The files designated
in the last step above are ready to create two CF cards to use in updating your DMU-2000.

*You must have two separate, blank CF cards (32 MB or more) and have a CF card reader slot.

NOTE: Do not copy the folders to the CF cards, only the files (V0.xxx WinZip and md5sum). The

system and the application files must be on separate CF cards. Do not save them to the same CF card.
Be sure the CF card does not contain any previous data or partitions. You may need to make a single
patrician and reformat a previously used CF card.

Now you will transfer each of the needed files to separate CF cards. When you op en the CF1 folder
you will see the two files. Copy both system files and paste them to the CF card drive and create a CF
card. Remove the CF1 card and insert another card. Now open the CF2 folder and copy or paste both
application files to the CF card drive and create a CF card.
It is strongly recommended that you mark each CF card as CF1 and CF2 to prevent mixing up the
files. The SYS file (CF1) must be installed before CF2 or the update will not work.

If you have version 03xx or 04xx, you must
create two cards; one with CF1_V008-sys and
another with CF2_V421-app.

• Open the CF1 folder and copy two files to

CF card 1

• Open the CF2 folder and copy two files to

CF card 2

DMU-2000_V008_2-25-10.zip

DMU-2000_V009_2-25-10.zip

If you have version 05xx, you must create two
cards; one with CF1_V009-sys and another
with CF2_V511-app.

• Open the CF1 folder and copy two files to

CF card 1

• Open the CF2 folder and copy two files to

CF card 2
