Sega CD Setup help

[FantasiaWHT]

Hi there!

I bought my sega CD cheap from somebody who didn't really know much about it, hopefully somebody here can help me set it up...

I have the model that has a "base" that goes under the Genesis (I think it's a model 2)

It's this: http://stifu.free.fr/Pics/combo.gif

Few questions

1) Do you need to hook up both spots for a power cord to an outlet? Just the base? Just the Genesis?

2) Do you need to hook up both the A/V out on the Genesis and the R/L audio channels on the base?

3) What is the little hole in between the R/L audio channels and the AC adapter hole on the base?

4) How do you get it to play off the CD instead of the Genesis?

Thanks![/img]

1) both the Gen and Sega Cd need power.

2) I just use the gen av cables.

3)? It says mixing so maybe mono sound?

4) Take the gen cart out.

1) Do you need to hook up both spots for a power cord to an outlet? Just the base? Just the Genesis?

Yes.. and you need a 3rd if you have the 32x.



2) Do you need to hook up both the A/V out on the Genesis and the R/L audio channels on the base?

Not with the Genesis 2.


3) What is the little hole in between the R/L audio channels and the AC adapter hole on the base?

Postman's peephole..? I don't have one in front of me so, I dunno...


4) How do you get it to play off the CD instead of the Genesis?

When you turn it all on, it seeks for a CD. If there is one in the drive, it will give you an option screen.

1) Yep. Each unit needs to be supplied with power
Sega CD 2 power supply. MK-1602 (Model 1 genny also)
Genesis 2 power supply. MK-2103
32X power supply. MK-2103

2) Sound output is through the Genesis but the extra output of the Sega CD will give you stereo for both. You could run these through stereo for example.

3) The hole = the Mixing input. I believe its used with the model 1 Genesis. From Sega CD FAQ (http://www.angelfire.com/ny/dezmoowu/Sega/bcantin.txt) "an audio cable is used from the headphone
output of the Genesis to the "Mixing" input of the Sega CD"

4) It will default boot to the Sega CD as long as you don't have a cartridge in the Genesis or 32X

Do you have a 32x? if so, You need a cable to go from the genesis to the 32x for it to work.

[FantasiaWHT]

Yeah I do have a 32X as well, I don't really use it.... if I did, it fits fine in the Model 2 Genny? (I also have a model 1 sitting around)

That's a relief that the SCD power cord is the same as the Model 1 Genny... now I need to see if I can find an AV or RF cord that fits the Model 2 Genny... lol...

Thanks!

[FantasiaWHT]

Hmmm something's not working

I have both power supplies connected (I know the Genesis one for sure is working because I see the red light. Not sure if the SCD is working, but the Genny by itself isn't working right either)

I have an RF connected from the Genesis to the TV.

I've tried both channels, tried switching the TV's input source from antenna to cable.

When I turn the power on, the static increases, so there is some sort of signal causing some interference.

How many pins are supposed to be in the RF attached to the Genesis? THere's a lot of holes, but I only see two pins.

I did see it demoed and working, so I'm at a loss :)

[Cauterize]

Is the red light comin up on the Sega CD?

if not youll most likely have to replace the fuse! and that is the only problem (a common one too!)

[FantasiaWHT]

No, I don't see a red light on the sega cd =(

And if I take the genesis off, shouldn't it work by itself? Or does that port on the right side that hooks into the base need to be fitted with something?

And how do I get that fuse?

[evilmess]

Not sure if this helps or not but here's a picture of my cord setup minus the powers supplies.

The Genny AV out to the 32X AV in and the 32X AV out to the TV with a power supply on each.

Have you tried cleaning the Contactacts on the genesis? And have you tried the CD with both of your Genesis systems?

And, the Sega CD will not work if you don't have a Genesis attached. (No power switch unless you mod it) To the best of my knowledge, Nobody has Modded a Sega CD to not require a Genesis to play..

[FantasiaWHT]

Dumb question, but you can't attach a model 1 Genesis to that Sega CD, can you?

And damn I stopped at work to do a few trades but I forgot to grab the other AV cable

You can but you need an adapter that was shipped with the Sega CD...

[Nez]

You can use a model 1 gen with a model 2 SCD.

[evilmess]

Yes you can attach a model 1 genny to a model 2 SCD. There's even an extension (http://www.goatstore.com/info.php?id=341905) you can buy so it won't look all wonky hanging over the side of the SCD.

I don't have this combination of hardwares so I don't know what it requires to setup. =\

[SkiDragon]

Just test the genesis by itself and see if that is the problem. If its not, then the Sega CD is the problem. You might need a fuse if its the CD system.

[FantasiaWHT]

Ok I found a good RF cord :)

I can get the Genesis to work fine, but I'm either doing something wrong with the Sega CD or it's just not working.

It looks like there should be a little red (?) light where it says "Access" on the Sega CD, but it doesn't turn on. I tried switching power cords, nothing different. I tried starting the power on the Genesis with and without a game inside and I never see anything for the Sega CD.

Any thoughts? Anybody do repairs on Sega CD here?

Any thoughts? Anybody do repairs on Sega CD here?

More than likely it's going to be the Sega CD's internal fuse...

http://www.mrvfone.com.au/sega/fuse.htm

I've done the repair on a Model 2, and it's pretty straightforward. Unless you have no experience soldering at all, it'd be perfectly reasonable to do the repair yourself.

[FantasiaWHT]

The last time I soldered I was probably 8. But I think I could do it...

Do you need to order the fuse specially?

Pop in a 850mA fuse (AU PAL Mega CD 2) Will be higher around 1-1.5 A for the MD 2 or SMS 2. (don't exceed 2A).

Or can you buy one somewhere? (Radio shack?) Other places?

Since it's broken won't hurt to tinker with it.

And a suggestion on exactly what amperage?

lakeflaccid's link is a good thing to try if you are able. :)

[FantasiaWHT]

Ok got everything open, found the fuse...

Can I check the fuse to make sure it's the problem with a multimeter?

Secondly, where do I get a replacement fuse? I opened up a Genesis model 2, but I don't see anything like that in there at all. I've got a model 1 I could open up, would that have it?

Thanks!

[soniko_karuto]

yes, if you don't have a multimeter, a 9v battery with an xmas light will do the trick. And yes, i've done it several times and haven't fryed anything.

[SuperShark]

Wait.

Before you start working on replacing the fuse and the CD, I must ask, do you have the metal plate for the Sega Genesis II to work on the Sega CD II poped and screwed properly into place on the botton of your Genesis? There is a metal plate that can withe the Sega CD II to hook onto your Sega Genesis that, I think, is proably required for the systems to work together. I have heard that this is unneeded, but whenever I have tried my Sega CD II on one of my Genesis II systems without it, it has never worked for me. With the plate however everything works great for me!

It is also possibe to hook a Genesis I to a CD II, as you have asked. The base extension that has been previously mentioned, while not required, will make the set-up look better and be safer (as in, when playing a cartridge it will be harder to shake the genny and mess up the game). This is where the mixing port by the CD AV outputs comes in. I know that the mixing cable is required to get CD sound to your Genesis I 's headphone jack, but i do not know for sure if it is required.

I also would like to offer you scans or retypes of any section (primairly the hooking-up-the-system sections) of an exclent condition Sega CD II User's Manual, and/or Sega Genesis II User's Manual (I am pretty sure to the location of these in my room, but if I am wrong, I promis to look for them till I find them for you). Just tell me so, and I am willing to e-mail you.

Hope I helped. :)

P.S.
Sorry that this is so long. I just started typing and could not stop! Wait. You See!?! I'm doing it again! I'm still typing! someone help me! Please. Wait. Wait. Wait! I'm still going on!!! Must Stop!!! *Hits self in head several time* *Hits a very long *SUBMIT**

1) Yep. Each unit needs to be supplied with power
Sega CD 2 power supply. MK-1602 (Model 1 genny also)
Genesis 2 power supply. MK-2103
32X power supply. MK-2103


I don't know but, My model 1 genny and my SegaCD 2, have 2 different power supplys.
Model MK-1602 : Input 120V AC 60HZ 20W Output 10V DC 1.2 A
Model 1602-1 (no MK on power supply) Input 120V AC 60HZ 16W
Output 9V DC 1.2A


Maybe there interchangeable, but you might want to try finding the same specs.

[FABombjoy]

For all intents those are equivalent power supplys. The output is the thing to look at, along with the polarity. 1V isn't usually going to make a big difference, since the function of the power supply is to feed the voltage regulators which typically have a wide operating range of input voltages.

The nice thing about the Genesis-era power supplies is that they usually won't fit if they're incorrect. A Gen2 power supply won't easily fit in a Gen1 and vice-versa.

RE: Metal plate. You really don't need the plate to get the CD unit working. It's possible that with the extra thickness, you have have improved or altered the connection to the EXT BUS and gotten those connections to work better, but I've ran plenty of Sega CD units without the plates in place (and so have many other folk).

[FantasiaWHT]

Drat.

Tried switching out the fuse! Took me forever, since I didn't have a precision soldering iron that I desperately needed. Still doesn't work =(

Probably going to save up some dough and send it in to the repair place suggested before :)

Anybody know any in America from these boards? I'd rather not pay for shipping to and from Canada.
