Some MegaDrive SCART cables also has pin 8 connected to the 5v, but that's just horrible, since it gives you 16:9.

If you only have a 5v to play with and no 9v (like in the case of the MegaDrive/Genesis), you'll have to put a 100 Ohm resistor between the 5v and pin 16 (gives you ~2v) to get RGB.

Depending on the TV set, there's a risk it will make the picture 'flicker' between CVBS and RGB. If you put 5v on the resistor instead of 9v you'll get ~1v on pin 16. That's why the official Saturn SCART cable has 9v on pin 8 and a 270 Ohm (?) resistor from the 9v to pin 16 in order to get both 4:3 and RGB. To get 4:3 you need 9v on pin 8 (according to the specs its' not quite enough voltage, but IRL it seems to work). If you put 5v on pin 8 the TV switches to the AV channel in 16:9 mode. If +5V is good enough for a Genesis RGB SCART cable why wouldn't it be good enough for a Saturn RGB SCART cable? The pin that outputs 9V on European models is Pin 1, not Pin 4. Then why can't you just rewire the cable to use Pin 4 instead of Pin 1? Pin 4 outputs +5V and from the look of the SCART cable pinout that's the one you should use anyways. If how ever you don't have the readings then your scart is not wired for rgb at all or 1-3v DC is missing from pin 16. if you see about 0.7v AC then red is ok.ĭo these test's and you should then know that your cable is working. If you see about 0.7v AC then green is ok. if you see about 0.7v ac then blue is ok. if you see 1-3v DC then cable is alright in that regards rgb should work.Ĭhange multimeter to AC reading and input red to pin 7. While multimeter in DC input black to scart outer gnd While saturn is hot and scart socket not connected to tv: So best test method if the cable is all right: No signal let's tv to decide the resolution. 9v will cause default to be 4:3 in pin8 and less than that will cause 16:9. This will cause tv setting default resolution and most likelly you can change between 4:3 and 16:9 from your tv controller. How ever there dosen't need to be connection to pin8. On pin 8-16 must be resistor there to change into RGB. Outer shell will come off easy and you will be able to see the inner connections. Every cord is connected to pin which is secured on the connector. The Jackal, there is no possibility to brake the SCART plug if you just open it up. That would be hilarious if there is 5v and is over the 3v so c-video all the way. So my guess is that no 180ohm resistor in 8pin to 18pin to give 1-3V to 18pin to select RGB. He is from GB so he should have pal saturn and everything ok there. Usually atleast Sony tv's supports this method via scart. Antoher possibility is to mix the raw sync into Green pin making your rgb to RGsB which is sony standart method to carry rgb. This will remove any c-video signals from pin8 but includes only sync and make scart cable only RGB option available. This means disconnecting pin8 and introducing there raw sync signal from video encoder input. Then only possible fix for bad quality cable could be canceling C-video going at all. Sometimes C-video can introduce crosstalk in the cable. So we can clearly see that only option to reduce crosstalk and dissorders is to add more voltage with bad cable. So you have the second option: Build cable with better sized wires in it. How ever this is not valid here because you need also give more cable thickness to harvest more current with same Voltage. This will carry more current, or if current is not added more, will cause less harmonic dissorders because wider bandwidth.Īdding more current. Only fix is to cut trace from pin4 in mobo and take 9v from here:īefore someone starts bashing that there is needed 1-3v for RGB signaling in pin 16 which is given with 180ohm resistor that there is no need for 9V:īasic electronics for signal carrying is that you have 2 options to less harmonic dissorders: How ever it seems that Saturn is outputting 5v which is causing troubles for some tv's to show RGB properly.
