Pro CD's on Pioneer PDR-05

3/01/98
DISCLAMER:

This is a do-it-yourself and do-at-your-own-risk job! I take no responsibilty if you damage your CDR unit! If the Drawer/tray won't manually go back, then DON'T FORCE it back into place! You may offset the gears!! The SERVICE MANUAL Does NOT show the correct gear setup!! Don't go swaping unfinalized Pro Discs. You can only FINALIZE a Pro Disc on the PDR-05!! You can use Green, or yellow dye CDR discs. Do NOT allow + or - 6 volts to go through the MAIN PCB!! This will short out the Power Supply B board!!

First, locate the drawer motor wires that lead to the loading mechanism terminal connector. This connector is on the PCB board on the far lower right.(SERVO UCOM BOARD) On the left side of the big ribbon cable, look for:

• CN202
• 5.GND
• 4.GND
• 3.LOAD
• 2.XOPEN
• 1.XCLMP

This is the connector I'm talking about! Wire Config:

• Black-Ground
• Grey-Motor - power
• White-Motor + power
• Blue-Lever Switch pin 1
• Purple- Lever Switch pin 2

All you need to do is power the motor. The Grey and white wires are to be connected to a + 6 or -6 volts
from 4 AA Batteries. The + or - 6 Volts reverses the drawer to open or close it! You'll have to figure it out
wich way it is. So, once the DRAWER is Opened, swap the consumer CDR with any Pro CDR disc you want!!!.
If anyone finds or makes a mod chip to defeat the "Consumer TOC CHECK", and defeat the SCMS copy protection,
please let me know ASAP !! (email to: darrens@erols.com)

The Step by step procedure:
ORIGINAL SWAP METHOD A:(WHILE POWER IS ON!)

• 1. LOAD IN CONSUMER CDR (must display NEW DISC)
• 2. REMOVE OUTER METAL CASING
• 3. UNPLUG MECHANISM CONTROLLER TERMINAL(see above to find this terminal)
• 4. MANUALLY POWER DRAWER MOTOR TO OPEN: use + or - 6 volts with 4 AA batteries.
• 5. SWAP CONSUMER CDR WITH A PRO DISC
• 6. Use + or - 6 volts to reverse the drawer closed(Or push the drawer back in fast by hand)
• 7. BEGIN RECORDING PAUSE MODE SETUP!!
• 8. FINALIZE When done recording! Don't finish the CDR later, Finalize it right away!!
• 9. RECONNECT LOADING MECHANISM CONTROLLER TERMINAL.Only when you've removed
  the external power supply of 6 volts to the motor connections!!
• 10. EJECT AND PLAY IN ANY CD PLAYER!! ( As long as you FINALIZED the Pro Disc!)
• 11. PAT YOURSELF ON YOUR BACK.. MISSION COMPLETED!!
• 12. REPEAT STEPS 1-10 TO BURN MORE PRO DISCS!

Note: You maynot have to reconnect the loading mechanism terminal connector. The CDR unit WILL perform another
"TOC CHECK" IF you Power OFF the CDR unit!!! Caution: The Unit might Display: "CHECK", just reconnect the
loading mechanism terminal connector. Then Power OFF and ON and it should go back to normal.

The Service Manual for the PDR-05 is about 45 bucks! This Manual is applicable to the following models and types:
KU PDR-99 & PDR-05 AC120v MEB PDR-05 AC220-230v Call 1-800-421-1606 Pioneer Parts dept. Tell them
its for your your retail store. Its so simple.. Pioneer parts are located in California and they UPS the manual and say it
takes 7-10 days for delivery!

Here's some tech info I got from a verry helpful friend when I was screwing around with my PDR-05 and ran into
problems..like, shorting out the power supply twice!

Hi Darren,
Today I checked the manual of the PDR-05. Here is what I've found out. 
The disc koading system works in this way:
IC 207 Pin54 is High during loading close (LIN)
IC 207 Pin55 is High during lodaing open (LOUT)
These signals are routed to a driving amplifier (IC 203) who inverts 
the LIN signal and not inverts the LOUT signal.
As the IC 207 outputs logic levels (I assume) that means 0V and +5V the
IC 203 (which makes no amplification or reduction of the voltage) 
outputs -5V or 0V or +5V. This signal is transfered to CN 202. Pinning
of CN 202 is:
1: from lever switch to ucom. This signal is High when the lever switch
is not closed to "CLMP". When the disc is clamped this sgnal goes low.

2: from lever switch to ucom. This signal is high when the lever switch
is not closed to "OPEN". When the loader is open this signal goes low.

3: loading signal from IC 203. This signal is -5V when closing, +5V when
opening and 0 V else.

4: GND for the lever switch

5: GND for the motor

So I think we have to inactivate the CLAMP signal and hold it high while
loading the pro disc. On the other side we need the signal from the lever
switch which says "disc clamped" to stop the motor. I think we need a
circuit which stops the motor when the CLAMP signal goes low and send a
CLAMP signal high to the processor.

Tech service:
Replace IC11 and IC 12 at power supply Board.
Resoldered connections in power supply

Thats what happened when I was trying to find another way around the
Consumer TOC Check.

Subject: FAQ Switch idea "1. Draft"

Hi Darren,

As promised the FAQ. Sorry for my bad English but this is all technical
stuff and I hadn't any good dictionary.
I attached one text-file which describes the different steps (it is only
a Draft!). Try to understand it. The best way to follow my idea is to
have a look at Excel diagram (register PDR05: simple solution), which is
also attached to that E-Mail.
I You have any questions - I will help You

FAQ "switch idea" to fake PDR-05

A: Material You need:

- small plastic box 20 cm x 10 cm (at least enough space 
  for a 4.5 V battery and 2 switches)
- Two 1.5 m long flat computer cables with 5-wires (each wire should
  have another clour). The cable should be so flat, that You
  can lead it through the cooling-slits at the rear of the PDR-05
- 1,5 two-wire cables (white and grey) for the power supply
- 1 switch (SW1) to swich five connections (to connevt or disconnect
  the terminal connector)
- 1 toggle switch (SW2) that can toogle tow-times two connections
  (up position
  open the drawer, down position close the drawer, middle neutral)
  (The swich must have at least 6 connections!!! Refer to my Excel-
  Sheet which is attached, really important. Show a electronic shop
  the drawing I made for You- he will give You the correct switch
  (hopefully!)
- 1 4,5-6 V Batterie 
- Soldering iron

B: How to do it:

If You have all material (A) You need You can start.

- Put in the plastic box two holes for the two switches (front) and
  in the rear one hole which is big enough for the flat computer
  cable 
- Unplug Your PDR-05
- Remove the metal case of the PDR-05
- Cut the 5 wires of the terminal connector in the middle of the
  wires. At the terminal connector should be left about 7 cm left
  One end of the wires which is connected to terminal connector I 
  will call "C". The other cables led e.g. to the drawer motor I will
  call D (refer Excel-file!)
- Take the flat computer and solder each of the five wires (Black
  Grey,White,Blue,Purple) (cable C) to the computer cable. If the 
  cable has different colours write down which wire colour of the
  computer
  cable is connected to which colour of the cable of the terminal
  connector!!)
  Make sure that these wires are isolated (short cut!)
- Lead that cable of the PDR-05. Use the slits at the rear of the PDR-05
  to lead out the cable (so You avoid to make holes in Your PDR-05)
- Lead that Cable in Your plastik box 
- Solder the other end of the flat computer cable to the "on" position
  of the Switch (SW1).
- Take the other (1,5 m) flat cable and solder it to the off position
  of the Switch. Take care that the same colour of the wires correlate!
  (e.g. blue-blue; white-white ..); Otherwise You damage Your PDR05
- Take the other end and lead it in Your PDR-05 (via the sits)
- Solder to the other the end of that flat cable to the wires (D). 
  Make sure that the colours are matching!!). Before soldering You must
  solder
  a 1,5 m white cable and a 1,5 m grey cable to the white and grey cable
  leading to the motor! (Refer Excel sheet point X and Y).
- Lead the other end of the grey and white cable ouside the PDR-05 (via
  slits) 

Result: Now You can switch on and off the terminal connector without
connecting or disconnecting the terminal connector!(Wahhooo!!); The 

switch will do it for You.

The following steps are really hard to describe. Therefore please refer
to the Excel sheet (which is much more deatailed).

- Now take the other end of the white cable and connect it to one of the
  two middle positions of the toggle switch (SW2); Point G (refer Excel
  Sheet)
- Connect (Solder) the other end of the grey cable to the second middle
  position of Switch 2 (SW2); Point F!
- Connect the up-position SW2(1) and the other of the
  down-position SW(2) to the +- power of the battery (Refer: Point "H") 
- Connect the down-position SW2(1) and the other of the
  up-position SW(2) to the - power of the battery (Refer: Point "I") 

Now it should work!!

When You do the swich2 in up position the drawer will close (or open). 
Down position via versa.
Never use that switch 2 the the Swich 1 is on (and connected to the
board: Short cut!!) (he means it could SHORT CIRCUIT the Power B Board!!)

If You have any Questions- ask me

Bernhard
  leading e.g. to the motor. Take care that the colours are matching!
