PD-6 Service Manual
3. SOFTWARE UPDATE
The PD-6 software can be updated by placing a software update file in the top directory tree on the 8 cm DVD-RAM
disk formatted by PD-6. There are two ways of copying the software update file from PC to the disk. Read through the
following procedures for proper software update.
3-1. MAIN PCB Software Update Procedures
3-1-1. There is an ATAPI, IEEE1394 or USB DVD-RAM drive exists in your PC environment;
1) Push down 2 pcs. of lock pins located at the lower left side on both
A and B sides of 8 cm DVD-RAM disk by using the tip of a ball
point pen, etc. Then, spin and move the lock pins out and around.
2) Take out the 8 cm DVD-RAM disk out of the cartridge and place
it in the indent of the DVD-RAM drive tray.
3) Extract the WinZip compressed software file “PD6VXXX.zip” and
copy the newly created software update file “pd6mXXX.mot” to
the top directory tree of the DVD-RAM disk. (“XXX” indicates
the software version number. If the software version is V1.02, the
software update file name will be “pd6m102.mot”.)
4) After copying the software, take out the 8cm DVD-RAM disk, put
it back to the cartridge and load it to the PD-6 DVD-RAM drive.
When putting a bare DVD-RAM disk back to the cartridge, be
sure that the side A of the disk conforms with the cartridge’s A
marking.
5) Power on PD-6. In the initialize stage, PD-6 automatically finds
the software update file placed in the top directory tree and is put
into the software update mode. The LCD example on the right
indicates that the PD-6 MAIN software is going to be updated to
V1.02 using the software file “pd6m102.mot”.
6) In the condition that the LCD example on the right is displayed,
press the ENTER key (knob) to update the software.
PD-6 starts updating the MAIN software. The LCD shows “Erase
ROM” (flashing) and then “Write PGM” (flashing).
7) After updating the software is completed, PD-6 is automatically
put initialized, booted up again and is put into the software update
mode. Press the EXIT key. (Depending on the current software
version, there is a case that powering off and then back on PD-6
might be required. Also there is a case that the display contents
differ from those listed in this page.)
8) Confirm the software version by the “Version” SETUP menu ex-
plained later.

PD-6 Service Manual
3-1-2. There is no ATAPI, IEEE1394 or USB DVD-RAM drive exists in your PC environment;
NOTE:
As mentioned in the PD-6 owner’s manual, depending on the operating system running on your computer, an
IEEE1394 driver software must be installed in your computer to allow to recognize the UDF formatted PD-6
DVD-RAM disk as a rewritable medium prior to the software update.
1) Select the IEEE1394 Utility menu and press the ENTER knob.
Then, turn the ENTER knob to right to select “CONNECT” and
press the ENTER knob again.
By putting PD-6 into the IEEE1394 mode, all functions are
disabled.
2) Connect the IEEE1394 cable between PC (Desktop PC: 6-pin,
Laptop PC: 4 or 6-pin) and PD-6 (4-pin) IEEE1394 ports.
3) Wait for a while until PC recognizes PD-6 with 8 cm DVD-RAM
disk loaded as an external rewritable removable drive / disk.
4) Extract the WinZip compressed software file “PD6VXXX.zip”
and copy the newly created software update file “pd6mXXX.mot”
to the top directory tree of the DVD-RAM disk. (“XXX” indicates
the software version number.)
5) After copying the software, select PD-6 (FOSTEX FX-FIRE IEEE
1394 SBP2 Device - (*)) and remove it from PC. (*: Drive No. on
your PC)
6) Disconnect the IEEE1394 cable from the PC / PD-6 and turn off
the IEEE1394 mode.
In the initializing stage, PD-6 automatically finds the software
update file placed in the first directory tree and is put into the
software update mode.
7) Press the ENTER key (knob) to update the software.
PD-6 starts updating the MAIN software. The LCD shows “Erase
ROM” (flashing) and then “Write PGM” (flashing).
8) After the software update is completed, power off PD-6 and then
back on. (Depending on the software version, there is a case that
PD-6 is automatically initialized and is booted up.)
9) Confirm the software version by the “Version” SETUP menu.

PD-6 Service Manual
3-2. DVD-RAM Drive Firmware Update Procedures
There are two firmwares for DVD-RAM drive, which can be updated by a similar method explained before. Although
the DVD-RAM drive firmware update will not occur as many times as the MAIN PCB software update, read through
the following explanation for correct update procedures.
1) Copy the DVD-RAM drive firmware update file
“mkXXXrev.bin” to the top directory of the DVD-RAM
disk either by direct software file copy onto a 8 cm DVD-
RAM bare disk or by putting PD-6 into the IEEE1394
mode and connecting to PC.
2) In the initialize stage, PD-6 automatically finds the
firmware update file in the top directory tree and is put
into the update mode. The example on the right indicates
that there is a firmware update file “mk0b1rev.bin” exists
in the top directory tree.
3) Press the ENTER knob to update the DVD-RAM drive
firmware.
The firmware update remaining time starts counting down.
It will take about 100 seconds (1 minute and 40 seconds)
to complete the firmware update.
4) After the software update is completed, the message “Pls
Power Off!” will appear on the PD-6 LCD. Power off
PD-6 and then back on. (Depending on the software ver-
sion, there is a case that PD-6 is automatically initialized

5. ERROR CODE / ALERT LIST
The Table below indicates the error code number and corresponding description. Since the error code list is basically
designed for our engineers to improve the software, the description is quite technical. If you find PD-6 displaying the
error codes, we encourage you to update the software to the latest one first. In case updating the software does not solve
the problem, we would like you to contact us.
4-9. BATT volt (Battery Voltage)
This menu monitors either the AC adapter DC voltage (POWER
SEL SW setting: EXT, EXT_PWR_DETECT fed to pin-238 (AN6/
PTL6/DA1) of CPU U6 (SH7727)) or the NP-1 type battery DC
voltage (POWER SEL SW setting: INT, INT_BATT_DETECT fed
to pin-239 (AN7/PTL7/DA0) of CPU U6). If the DC voltage is
around 15V, the 4-digit hexadecimal value will be around 0240.
