Is this the Sega CD 2 AC power cord that works on the DUO?

I've been searching for the correct model # and a place that's selling a Sega CD 2 power cord. I'm hoping this is it.

I'm also looking for the AV cable or a replacement option.

Thanks!!

Dunno I will test mine tonight and compare specs

Here's the image:

The picture is a Sega CD 1 adapter, not 2.....the 2 tip is yellow, and specs are all wrong.
Specs on this Genesis/Sega CD 1 adapter are:  10VDC, 1.2A, tip NEGATIVE.

Duo_R has written up something on how to convert this.....basically cut the end off, strip to your liking, it requires a "Q" tip from Radio Shit (right?) AND reversing the polarity on it to tip POSITIVE to comply with the Duo's 10VDC, 1A, tip POSITIVE spec.

Hope this helps....

[Duo_R]

ok, so here are the Duo's specs:

DUO:
Input: 120V AC 60HZ 16W
Output: 10V DC 1000mA
Center plug is positive, the outer is negative.

got that from here:

how do the specs match up on the Sega CD? So 10VDC and 1.2A - that looks good. Now is the outer tip negative or positive? If it the out connector is negative and fits we have a winner. If the outer tip is positive, then we need to reverse polarity. There are markings on the AC Adapter and on your system that indicate the polarity (so u can see if they match).


*duo runs to see if he can find his little converter box*

So this is a converter box, this is actually a Sega CD 2 to Duo-R adapter box I built. The specs were inline, but the polarity was off. I built a little box to swap polarity. Salvaged a plug from an old cordless phone I am no longer using, the box used to belong to my Duo's region switch box, cable was hacked off a Japanese Genesis cable that I didn't need.

Nice! Thanks for the info.

Here's this: http://www.pcenginefx.com/forums/index.php?topic=2086.0

I hava a Genesis 2 power supply, but it has the yellow tip and doesn't even come close to fitting the duo. It's specs are.
10V DC 0.85A

I guess I'll go the Radio Shack route. Pick up Q tip and try to reverse the polarity if need be. Not sure if the Genesis 2 power supply will work. If not, I'll order the Sega CD.

So this looks like another solution. Kind of expensive though.

So, will the Adaptaplug Q and the 9.0VDC International-series high-power AC adapter from Radio Shack work?

Just looking for cheapest and easiest route. Don't mind doing a little modding.. I'm not much of an electrician, but I can follow a tutorial.

OK, I've been seeing conflicting information on this Genesis 1 adapter, so I pulled out my box of them and inspected....here's what I came up with:
1)  Sega Genesis/CD 1 adapter, Model 1602:  9V DC, 1.2A, tip negative, type M.  [this has been the source of my confusion]
2)  Sega Genesis/CD 1 adapter, Model 1602-1:  10V DC, 1.2A, tip negative, type M.
3)  Sega Genesis/CD 1 adapter, Model 1602-3:  10V DC, 1.2A, tip negative, type M.
[didn't find a "-2"]

In terms of electrical stability, the later the Model, the better off you're gonna be.  Hit up the local flea for the $1 "1602-3", cut the end off (noting which wires were negative and positive), solder on the "Q" tip in the required tip positive manner and you should be good.

DR is talking about literally that:  a Duo-R.  Is the AC adapter spec for this the same?  This would explain why he's talking about a Genesis 2 (Sega Genesis/CD 2 adapter, Model MK-2103:  10V DC, .85A, tip positive, type C), but Chopsado talks about running a regular Duo with a Genesis 2 adapter (and the unique tip size adapters!) in this thread:

I'm totally confused about this, the mA for it is too low, I'd think you're underpowering the thing, but he said it ran better.....the mA rating is the MAX amperage the thing can provide.  If the manufacturer shipped it with one that says "1000mA", wouldn't you think something inside it is capable of drawing that?  If this is true, then 850mA is underpowering it....the fact that the thing apparently works better is puzzling.

Anyway, check the mA on the generic Radio Shack....if memory serves, it's like 1300, which would work, provided the max amperage on the unit originally provided by the manfacturer was 1000mA....in theory, the unit is incapable of utilizing the extra 300mA in this case....

Comments, anyone?

["Dammit, Jim, I'm a doctor, not an electrician!" seems strangely appropriate here]

Sweet! I'm starting to get it now. Great Trek quote btw!

I have a Model 1602-1 from my old Sega CD. So I'll use that with the Q tip I just picked up from Radio Shack.

So, it's almost solved. Just need to do the soldering work... and I need to get the AV cable worked out. Then I can test my system.. which I think might be broken. 1 step at a time.

[Duo_R]

Ok,


the original post he is saying he needs an AC adapter for a Duo. So again here is the specs:

DUO:
Input: 120V AC 60HZ 16W
Output: 10V DC 1000mA
Center plug is positive, the outer is negative.


The output specs is what we need to pay attention to: 10V. You want voltage to match almost exact, more or less isn't ideal. Now mA is different, the important thing is that you need to have something AT LEAST 1000ma, you can actually have more mA (or A) since the Duo will only pull the juice it needs. Going less on mA is not good for the system since it isn't providing enough amperage (regardless how someone says it is running). OK? 

I'm totally confused about this, the mA for it is too low, I'd think you're underpowering the thing, but he said it ran better.....the mA rating is the MAX amperage the thing can provide.  If the manufacturer shipped it with one that says "1000mA", wouldn't you think something inside it is capable of drawing that?  If this is true, then 850mA is underpowering it....the fact that the thing apparently works better is puzzling.

Mmm...froggot to mention that Sega Genesis/CD 1 AV cables will work fine for the Duo....I traced the pinouts the other day on both the two-tail (yellow/white) and three-tail (yellow/white/red) ones, they both comply with the Duo spec.

Nice! THanks for the info! I'll be rocking in no time.

[gat]

Sweet. I don't have the AV cable, but just picked one up off ebay.

[agt_dale_cooper]

Uh, if that's the AV cable in question, it ain't right.
That appears to be a Genesis 2 AV cable...what you need is a Genesis 1 AV cable, 5pin DIN interface....[refer to previous post text..]

Here's a nice little make your own Genesis 1 AV cable (Radio Shack is going to get tired of seeing you) :
http://www.stageselect.com/News/NewsViewer.aspx?newsid=174

Just make it comply with the Duo spec:

(Note that pins 1 and 5 are the same, just wire in pin 2 to red and off you go....)

[gat]

I have a 5 pin cord that fits the duo.

Like this



but in chord form. I stripped it and it has yellow, white, red and black along with the copper. Would I be able to wire this to a standard AV cable?
