Late last night I replaced the old caddy drives on my DTS 6D two drive unit and when I turned on the power I got the system light but the drives wouldn't open. I guess there is no power to the drives, I checked the power cables to the drives and there in the socket the only way they can go in due to the shape of the socket and wire bundle. I looked at the power socket for the old drives I took out and they are upside down compared to the new ones. The power supply is fairly new, and I don't think there is anything wrong with it, but I seem to remember that it was hard to wire the power supply to the older drives I had.

I guess my question is, if the power socket is upside down but the pins in the socket aren't, then I need to pull the wires from the bundle and reverse their order, right?

No. Don't do that. it will realy screw things up. The plugs on the power cables are keyed to fit only one way.

By the way....where did you get the drives from? DTS uses SCSI's.

If the drives do not power up, I think you have problems elsewhere.

The sockets follow a standard layout and there is no standard whether they are mounted upside down or not
Check the ScSI ID setting the termination and the data cables
Did you install theupgrade firmware and scsi cards

Posted by Paul G. Thompson (Member # 655) on 01-04-2003, 01:15 PM:

Gordon is correct.

Make sure your ID's are set properly, and make sure you are using the correct SCSI controller. Make sure the drive ribbon cable is properly terminated.

.....and be sure the ribbon cable is not plugged in backwards.

Did you get an upgrade kit from DTS, or did you just go out and buy the drives? If you just bought drives, then you need the rest of the upgrade kit parts to make it work properly. The data has to be clocked down coming out of those much higher speed CD-ROM drives so the computer can crunch it. Firmware also HAS to be upgraded so it will read the TC properly. The kit comes with complete step by step instructions.

I upgraded to the TEAC drives and I got them from DTS, I followed the instructions word for word and had no problems with the install. However, when I was done and turned on the power I got no power to the drives, and upon further inspection I saw that the new drives power socket is upside down compared to the old drives, so hopefully the pin order is different on the TEAC drives. Also, I re-used the old SCSI cable becasue the new one had 4 terminations (for a 6-AD).

Involved in the install were the two new CD drives, a new SCSI card and another card with the AQRM chip. I replaced the firmware chip and removed the DOS chip as instructed. What is the SCSI ID setting and how do I check it?

Posted by Mark Gulbrandsen (Member # 72) on 01-06-2003, 07:54 PM:

I just did one about 2 hours ago and it worked fine. Be sure that you don't have the SCSI cable reversed at the SCSI board as it will seem like the drives are dead. I tried various things in thinking about your problem and got it to act dead this way......Other than that, its pretty cut and dried.
Also, the new instruction as done by Film-Techer Karen Hultgren are really well done Karen!!

On CD drives, the SCSI ID is usually set with one or two jumpers on the back of the drive. There should be a label on the top or back of the drive which indicates which combination of jumpers will set the drive to which SCSI ID. Each drive needs to have a unique SCSI ID. I don't know if DTS has any more specific requirements. Try connecting only one drive at a time and see if it powers up.

As others have suggested, make sure that the SCSI chain is properly terminated and that the drive cables are attached properly. The power connector is standardized, so the orientation of the connector on the drive itself is irrelevant--it is designed to fit only one way and that way will provide the correct pin order.

BTW: has DTS considered using Plextor drives? They seem to make the best SCSI CD drives (and burners) on the market at this time.

Ok, the SCSI 1D jumpers are where the instructions indicated, I made sure of that but I wasn't sure what you meant. I put the SCSI cable on the drives and back to the board with the red wire as pin one, I don't know how I could have done that wrong, but when I go into work I will see if any of the pins are bent or are out of position. Thanks for all your help guys.

I am not sure if the red wire on the drive power is +5 volts or +12 volts, but if you plugged it in backwards, (extra force is needed to do that) don't be surprised to find out you toasted your drives. I would suggest you re-install the orginal drives to make sure the entire unit still works.

Posted by Daryl C. W. O'Shea (Member # 1303) on 01-06-2003, 11:17 PM:

Red / Black / Black / Yellow
+5V / 5V GND / 12V GND / +12V

Thanks, Daryl

I had no problems with the power connections.......that is all standard stuff, they may be 180 degrees rotated from the old connectors, but the pin out HAS to be the same.

I cannot believe that a PC power plug can be inserted upside down! You have to phisically destroy it!

And, Michael, don't worry if the connectors are upside-down, the connections inside will be the same

Bye

Michael,

DO NOT REWIRE THE POWER!!!! You will destroy the drives.

All the drives we have used have the same power connector wiring. The power in connector is "keyed" for that reason.

Did you get installation instructions with the drives? I recently upgraded those instructions with photos. You must carefully follow each step - replacing software chips, taking boards out and putting in new ones, and installing the drives io the correct order.

It sounds to me that the DTS player is not booting. Spinning up the drives is the last step after the system has been checked (during the boot-up process). If there is something wrong with the player, the drives will not spin. The player's SYSTEM light must blink or the player is not fully booted up.

If the player didn't boot before the drives were replaced, it could be that your motherboard has died or something else is wrong. In that case, an upgrade kit won't help.

If you need the instuctions, please send me an email. If you followed the instuctions and the player will not boot, then you should send the player in for repair. You can contact me on that as well.

Thank you,

Karen at DTS

Yeah, Antonio, I know....but unfortunately, I have seen it happen....

Posted by Daryl C. W. O'Shea (Member # 1303) on 01-07-2003, 01:48 PM:

Me too Paul, some of the early Molex connectors would break on both sides above the cut corners allowing the male connector to be inserted both ways. Come to think of it, I believe I made a bit of money because of that poorly injection molded part.

Paul

What damn does people use to connect a CD-ROM drives? An hammer????? [Eek!]

Posted by Paul G. Thompson (Member # 655) on 01-07-2003, 10:04 PM:

Antonio, you guessed it... [Big Grin]

Actually, Daryl's comment is very accurate...

Oh, by the way - I had some computer technician tell me once that a Microsoft Bus Mouse can be plugged into a PS-2 mouse hole, and vice versa and it would work. When I questioned that tech's birth rights and a few other things, my German and Norwegian temper did get me in hot water to the point where I was asked to leave the establishment. (In short, I was almost thrown out of his shop.)

(I might add that the establishment who had that tech went out of business)....

However, I still think Michael should re-install his old drives to verify the unit is still working so he has a "benchmark". Then he can start over or send the unit back to DTS for repair and upgrade.

Thanks for all your help guys it was the SCSI cable, I had the cable plugged into pin 1 on the drives, but pin one on the SCSI card was the opposite that of the drives. I couldn't tell from the black and white picture on the instructions where the red wire on the cable was going to the board, and there was a number 1 on the right hand side of the board next to the pins, so I mistakenly put the SCSI cable in backwards. It didn't take me this long to fix the problem, I fixed it and went on vacation and decided to let everyone know what the problem was because I know you were all on the edge of your seats.

Thanks again guys, and Mark, for guessing the problem you can have the giant Spongebob Squarepants doll I won at the Excalibur on the ring toss.
