Just a quick update - as mentioned I couldn't find any documentation for the serial commands on the (PAL) LD-V6100 - which seems to be because it's from the same group as the 'LD-V6000A' series NTSC industrials - that is, the LD-V6000A, LD-V6010A and LD-V6200A, which superseded the original LD-V6000, LD-V6010 and LD-V6200.

There is a manual for serial control of the non-A series here on lddb (TP109 Version 2.0), but there is a later version of that manual (TP109/A Version 4.1) which had supplemental pages covering the -A series - the combined volume was at least 156 pages, compared to the 65 pages of Version 2.0.

I know this because one was sold a long time ago on eBay - but all I have are a few tantalising images from WorthPoint! (I contacted the seller but he had no record of who'd bought it).

I recently acquired two industrial players and I've built a cable to talk to them. I thought I would document the process here:

1. Buy a male DB15 connector and a female DB9 connector.
From DB15 to DB9 connect:
  • GND-GND
  • TXD-RXD
  • RXD-TXD
  • DTR-CTS,CD,DTR,DSR
Pioneer sold this as Pioneer Cable # CC-13. PacParts still has at least some variant of this available for order, but it is of course quadruple the cost of making one.

2. Buy USB to RS-232C converter. I believe I purchased mine at RadioShack long ago. Mine was made by Prolific.

3. If you don't have Linux running somewhere, install it on VirtualBox. I used Debian 9. After the OS is done installing, go to Devices -> USB and select your USB/serial converter.

4. Ensure your player is set to 4800 baud. On most players (all?) this is controlled by dip switch two on the back. It should be off for 4800 (up position).

5. ls /dev should show ttyUSB0. You can begin communication with stty. For example stty 4800 < /dev/ttyUSB0; echo -e "OP\r" > /dev/ttyUSB0 should open the door.

6. If you want something a little more robust, install minicom. Start with minicom -s and go to device (A) and set to /dev/ttyUSB0. Go to serial port setup (E) and change speed to 4800. Disable hardware flow control. Save setup as dfl.

I'm currently writing a library to make it easier to interact with these players. Controlling these players through software is pretty cool and can be useful. For example, it is possible to disable repeat play which is pretty annoying on these players, set the player into test mode, change background from blue to black, play at half speed, get your player's hardware revision number, etc.

Next up is to buy the barcode software Pioneer made to see if barcodes can be created from the more useful commands.



I bought a 15pin to USB adaptor which is what is on the back on my Pioneer cdl-v2600 . All drives updated using FTDI . I can't get the domesday duplicator capture to show its connected . I do have the serial connectors on the back of my PC as anothor option . I was told the serial to usb would be fine . Not so far . Any suggestions ?

Did you go through the whole process - checking the speed (baud) settings especially, both with the DIP switch(es) on your player and the settings in the Domesday software?

I don't know much about the Domesday Duplicator, but what I could find suggests that its "Player Control" only supports the Pioneer LD-V4300D and the Pioneer CLD-V2800 - so not your player?

You could try the "DOS Test" software linked to in this thread to see if you have any joy with that - it supports the CLD-V2400 which sounds quite 'close' to your CLD-V2600.

But as I understand it, Domesday "Player Control" is only a 'nice to have' and it won't affect your capturing efforts beyond having press 'play' and 'stop' periodically?

HI , Thank you for your help I really appreciate it . Yes the setting on the back are all in the off position , I have 4 dips on the 2600 , All the Industrial players should all work the same some have 2 dips and a few have more then 4 but they all are supposed to work with the Domesday . I changed the setting in the port to 4800 and still nothing , There is not all that much to change in the capture software but I will look again . Something I'm not doing right . what is the DOS test and how do I find that and run it ? I'll add anyone looking to do a domesday duplicator must have a lot of old skills wiht command and script which I have no clue on as well as electrical skills , I'm in over my head and i'm close to giving up and just selling the DD and the ld2600 player (its almost new inside and out) , I have a slightly better player for my backup and might just go back to using my PVR recorder or even a dvd recorder. Though hate to after all this time and money spent . Thanks !

Yeah. It’s literally the most hardcore way of recording anything ever. I have a feeling there are a lot of unused boards out there just because the barrier to entry is so high and the way people get themselves into this is they come to a forum with the vague idea there is somehow value in making copies of things that they already have and before anyone asks “Why bother?” a dozen GAS effected heroes list all the stuff you need and where you need to buy it from and within an hour you now have what is by all description an effn’ JOB to do and while it’s probably not too hard for most people to eventually figure out it’s obviously way too difficult and time consuming for me to do.

Perhaps it’s a noob thing. When someone gets their first LD the very first group think that gets injected into their brains is rot. “It’s such huge problem, it affects every disc it’s only a matter of time, etc.” Then they look at their “new” LD they for some reason spent $400 on and start to think that it needs to be preserved ASAP before it’s gone forever. If you’ve had discs for 30 years and they still play fine the manufactured urgency never manifests itself.

If you have something totally unique, it’s worth it. If you have something there are only 8 of and the other 7 people haven’t done a Domesday level recording it may be worth it. Laseractive games are a great use since they contain much beyond just video that is basically impossible to get any other way. The vaaaaassst majority of all LDs are simply not worth archiving at all.

If you want to make a copy of American Pie or Jingle All the Way or some other common trash that not only exists in professional HD/4K rescans making the work useless it’s also work that is already been done by a million “archivists” then I’d seriously advise just not doing Domesday and spending more time with your friends and family or just watching your LDs.

The DOS Test software is here:
https://laserdiscarchive.lddb.com/laserdisc_archive/pioneer/pioneer_pc_rs-232_control_software/pioneer_pc_rs-232_control_software.htm

...and there's a post further up this thread (by me!) that covers it, including running it in 'Dosbox'.

As I say, I'm not an expert on the Domesday Duplicator, never having used it, but I'm pretty sure that the Player Control feature would not really be necessary for capturing. The alternative, once you've got your RF connection sorted from the player to the DD box, would (I'm guessing) simply be to press "Start Capture" (or whatever) in the software, and then 'play' on the LD player...

So nil desperandum!

But if you're daunted by other aspects of DD, you might do better starting a separate thread on Domesday generally, as this one is a bit 'niche' on player control.

Regarding signofzeta's post, I'm sure much of what he says is true. However 'Domesday Duplication' does sound like a technical marvel, and, if the hardware were a bit cheaper, I would definitely be wanting to have a play with it - not because I want to capture unique LaserDiscs, just because it would be interesting and fun to set it up and see it working!

The discs i'm doing are my favorite concerts from the 80's which do not have a better fomat and been messed with way too much on Youtube with there crappy compression and amature video AI tools . These discs will never be available on anything better and I was hoping to preserve them for myself and friends who like the music . There is no way on earth I would be watching a LD if theyre is a blu-ray or 4K out . I have a big collection of pysical media , Newbie i am not , Been buying these since my first disc in 1990 . I'm actually glad I didnt go crazy with movies on LD or DVD , Just bought tv shows on dvd and concerts / music videos on LD when blu-rays came out that changed everything for me . Now I pretty much only buy 4K uhd and upgrade all my blurays and sell them when I get a nice 4k scan . The DD id a absolute nightmare , Very hardcore indeed .

Thanks for that , Yes I know you don't need it to capture , But it can help quite a but + has a remote app , I don't have a remote (one of those giant monster ones) I really don't want to buy one . If your not trying to preserve and archive stuff you can't get aywhere else I would never recommend this . Its not even about the money it cost . Yup , I'll leave this thread for serial connectors .

Tried pretty much everything . dosbox , virtualbox, kind of hard to do all that , the software download is from 1995 , the read me file showed that V2600 is listed . This is all just too hard . Maybe it need a special cable . I bought the best one you can get with the FTDI chip . cable comes up fine on my pc with the lastest drivers but i give up . There is a timer on the domesday software which will stop the capture so that will have to do for now . The rest is way above my knoledge . And I cant spell LOL . Might as well return thr cable since it was $50 . Thanks ...I tried now back to the other nightmare the DD .... I'm close to figuring it all out I think .

That is the Computer USB to DB9 serial... but what is the pinout of the DB15 you are trying to interface?
Did you follow the Pioneer DB15-DB9 pinout?

I don't think this is the standard DB15-DB9 pinout where GND goes from 5 to 7, not 5 to 1?

I was banging my head on the walls not succeeding in interfacing a MOXA serial cable switch with standard devices...
Until I realized that the CISCO "standard console cable" I was using were different from the MOXA "standard console cable" I should have been using.

And then everything worked!

Julien

PS: nice to see they even had a pin-out for the Commodore Amiga!

I'm using a DB15pin to USB , The DB15pin is what is on the back of the Pioneer and its the only one I found that fit directly on . I have no idea about how the wires are inside but after watching a video looks like you have to build one for this type of project to get it to communicate . No idea how to build a cable . But thank you very much I really appreciate it .

Yes, DB15 is the connector type, but the inside wiring can be completely different from one device to another.

The DB15 on the player side is only using pin 1, 2, 3 and 4 which is quite unusual.
This is probably why the CC-13 is a "specialized" cable from Pioneer, the pinout is custom.

Thats what I kind of figured the Pioneer cc-13 was made for this and why people have to build there own . One guy on a video talks about it but he never shows how to do it . Its ok, I would not really know how to mess with wires . Maybe I can try and find a Pioneer cable or another option but its not super necessary at the moment , Thanks :)

If you are "technical" enough to understand and use the Domesday Duplicator, you should not have much trouble making your own 9-pin D-sub to 15-pin D-sub cable, without having to solder anything. Get these two devices or their equivalents from other sellers, and a common "Ethernet" (RJ45 male-to-male) cable:

Customizable "DB-9" female to RJ45 adapter:
https://www.amazon.com/StarTech-com-Serial-adapter-DB-9-RJ-45/dp/B00006IRQA

Customizable "DB-15" male to RJ45 adapter:
https://www.amazon.com/C2G-02926-RJ45-Modular-Adapter/dp/B0002J1JCM

With those customizable adapters, you can make any pin on one end go to any pin on the other end, by matching the RJ45 connector pins to the desired "holes" on the empty DB-type connectors. For example, connect the RJ45 pin 1 wire on the DB-15 adapter to DB-15 pin 1, then connect RJ45 pin 1 on the other adapter to DB-9 pin 5, and so on.

The one catch may be if the computer software does need all four of the DB-9 pins (1, 4, 6, and 8) connected to DB-15 pin 4. Then, you would need to (for example) cut the wires from the DB-9 adapter's pins 5 through 8, put those pins into DB-9 holes 1, 4, 6, and 8, then remove insulation at their cut-off ends and twist all four bare ends onto (for example) the pin 4 wire from the RJ-45 in the DB-9 adapter.

I hope I did not make all of this sound more complex than it really is. I could draw and post an exact diagram of it all if that is desired.

If you are "technical" enough to understand and use the Domesday Duplicator, you should not have much trouble making your own 9-pin D-sub to 15-pin D-sub cable, without having to solder anything. Get these two devices or their equivalents from other sellers, and a common "Ethernet" (RJ45 male-to-male) cable:

Customizable "DB-9" female to RJ45 adapter:
https://www.amazon.com/StarTech-com-Ser ... 6IRQA?th=1

Customizable "DB-15" male to RJ45 adapter:
https://www.amazon.com/C2G-02926-RJ45-M ... J1JCM?th=1

With those customizable adapters, you can make any pin on one end go to any pin on the other end, by matching the RJ45 connector pins to the desired "holes" on the empty DB-type connectors. For example, connect the RJ45 pin 1 wire on the DB-15 adapter to DB-15 pin 1, then connect RJ45 pin 1 on the other adapter to DB-9 pin 5, and so on.

The one catch may be if the computer software does need all four of the DB-9 pins (1, 4, 6, and 8) connected to DB-15 pin 4. Then, you would need to (for example) cut the wires from the DB-9 adapter's pins 5 through 8, put those pins into DB-9 holes 1, 4, 6, and 8, then remove insulation at their cut-off ends and twist all four bare ends onto (for example) the pin 4 wire from the RJ-45 in the DB-9 adapter.

I hope I did not make all of this sound more complex than it really is. I could draw and post an exact diagram of it all if that is desired.


Actually the Domesday is plug and play with some flashing done , Not hard at all , Anyone can do that .

This seems very complicated , A Ethernet cable is also throwing me off , I thought were suppose to use a serial cable ? I do not have a serial connector on my computer . It would have to be a USB type that I have been told works , But so far none have worked for me , Pioneer made this cable to charge a lot of money . Cable is proabbly $5 and they charged $80 for it . if you can help me try and do this I would really appreciate it . What ethernet cable would i get . and or is this a option , though the back of my LD player has a DB15 . https://www.amazon.com/gp/product/B01MF ... PTLEA&th=1 Thank you very much . :)

I think in this example the ethernet cable is just being used to link the two serial-ethernet adaptors together - so it's not carrying ethernet signals at all, it's just a way for you to use those nifty "customisable" connectors.

For what it's worth, the way I got my player connected was to buy a dirt-cheap PCI-E serial card, to give my PC a DB9 serial port. Then I got a DB9 to DB15 adaptor, and connected that using the original DB15 to DB15 serial cable that came with the player, and it all just worked.

I didn't actually realise that the serial cable didn't use standard wiring, but if that's the case, if you have a soldering iron, you should be able to get a standard serial cable (again very cheaply) and unsolder and resolder the wires from the pins at one end to get it working (and I'd advise checking the results with a multimeter before connecting).

That can be a bit fiddly, especially if you haven't soldered before (?), but it's all good fun!

The common names/terms used for items can make things confusing if you are not already "used to dealing with that", so I can understand being thrown off. As yaffle2345 commented, the "Ethernet" cable used in my do-it-yourself plan just needs to be "a cable with RJ45 male connectors on both ends, with all eight pins of each connector wired to the matching pins on the other end", so that it matches the customizable adapters.

The Amazon link that you posted is for a "serial port console cable", which is another use of RJ45 connectors for something that is -not- Ethernet. (The listing does not help when it mentions "Ethernet" and also "USB", since this cable does not work as-is for either of those functions!) This cable essentially combines the` "RJ45 cable" and the "DB9 to RJ45 adapter" into one cable, but it has a male DB9 rather than the female one you need, so it is not a good choice.

Also as yaffle2345 mentioned, if your computer does not already have a serial port (with a DB9 male connector, standard for serial ports in recent decades), you need to add one, either with a PCI-E serial adapter board or with a USB-to-serial adapter/cable. (If you get a USB adapter, buy one with an "FTDI chip" rather than "Prolific", and be sure it has a male DB9 serial connector, not a female one.)

I should be able to make and post a drawing of how to do the setup I described, tomorrow.
