HANTAREX CT 28 EQ MONITOR Only Outputting Composite Picture!

[lettuce]

Scrap that, i just tried a different MM and test neg on pin 18 and live on pin 16, and im getting a dead 5v reading!, so maybe this just isnt quiet enough to trip the monitor into RGB mode?, still strange that my TV doesnt switch over to the Scart channel when i turn the snes on though it im getting 5v on Pin 16?

[fagin]

Well.... This is what doesn't make sense, as RGB switching should be on PIN 8, yet your manual says that isn't connected!!!! PIN16 should be the blanking signal.

The wiring on that CRTs socket is all to cock and I suspect part of the issue!

Yeah i know its is a knightmare, i was just hoping to plug it in and bame! would be working and could enjoy some lovely UN Squadron, but spent most of Sunday trying to get this thing to work!. But wouldn't have got as far/had so many ideas without your help Shaun so i appreciate it..............just none of them have bloody worked yet so sort it out lol

So do you think i should try connecting a wire up to pin 8 and then to pin 16, so both pin 8 and 16 will be getting 5 volts??

[fagin]

LOL

The reason your SNES does not RGB switch your TV, is because you have a poorly built SCART lead - don't worry about it as it's a slight red herring in this situation.

The SCART connector on the back has it's wiring to pot!
This is how I read it:
1) If you connect CVBS it will use that for composite video only
2) RGB requires separate H & V sync (which is crazy imo)

Let's look at the D9 input - if it's EU then you need H & V Sync. You can't use a CSYNC - that's for the US only. Doh! (Who fuck changes that kind of spec between countries).

Whichever way you jump - you'll need proper H & V Sync.

Now (I think) comes the crippler.... I'm not 100% sure a SS gives a proper H & V Sync output.

Someone has commented on the other thread about this and he said he built a LM1881 circuit (the same as what I did for the CGA2VGA video and thread on here). Based on the findings and advice from others, that is exactly where I would be looking now.

Whereabouts in the UK are you?

[lettuce]

So i need a LM1881 then?

Im based in Bedfordshire in East Anglia mate

[neorichieb1971]

I tried about 3 scarts that all work on normal TV's that don't work on Hantarex configured scart sockets. It doesn't matter if I tried the DC or the PS2 (import or not).

Whatever this Hantarex is supposed to do its not built with general scart specification in mind.

I also live in Bedford, now thats a global one in a billion coincidence.

lol, its a small world

Well that's what the guy on the other thread said and I assumed was tried successfully.

[neorichieb1971]

I never tried anything successfully. I did not try the sync splitter though. I'm not a techie kind of person. I can take apart scart leads and blow really hard into them hehe.

What I don't get is if the monitor doesn't take composite sync how can it take composite video?

Im not sure im still 'green' when it comes to video and sync atm, Fagin might know. I bought this Monitor as i thought it would just be like a standard Hantarex polo star monitor just in a TV casing, how wrong was i they have seems to have completely butchered the connections

[fagin]

A number of things on this monitor don't make logical sense.... so nothing would suprise me.

Using composite video for sync on it's own and using it for the actual video signal are totally different. Just because it takes one, does not mean it will take the other.

[lettuce]

I CANNY BELIEVE IT!!!!!!!

Ive only just gone and sorted it!!!!!

I managed to get the sync sorted but the display still looked like a Nintendo Virtual Boy!!!.....



And after another half an hour of trial and error, i got this!!!.....



When me thought the pinout diagram was all to cock....well that was an understatment. This is what the pinout is for the wires i know at the moment...

NEW REVISION


OLD


None of the pins on the diagram in the manual were correct at all...not even close. Now how can i find out what the Black, Purple, Blue and Red wires are?, and why is it sync'd for just using H sync on the grey wire. Do you think 1 of the other 4 unknown wires are the V sync?

The picture has an ever so slight 'judder' to it any ideas how to make it rock solid stable?....im fairly pleased with my self i was about to lob the monitor in the skip!!!

I will take the MM to the 9din later on and get the correct pins to the correct wires

Also i need to figure out what i need to do to my SNES scart in order to get it to sync on the Scart connection, my head hurts too much atm to think about it lol

[lettuce]

Ok a bit more info, it would appear the black wire is also Sync, as if i remove the grey (sync) wire and then attach the black wire to either H sync or C Sync the picture also stabilizes. So is the black wire H sync and the grey V sync or the other way around....or neither??

Regarding the 'juddering' picture, i have sorted that by upping the juice on my adapter connected to the SS from 6v to 9v.

Here is the 9DIN pinouts...

Pin 1__________B
Pin2___________G
Pin3___________R
Pin4___________Unknown
Pin5___________Ground
Pin6___________Sync
Pin7___________Sync
Pin8___________Unknown
Pin9___________UnKnown

So it the pinout diagram in the manual is to believed (why would we) out of the Blue, Purple and Red, 1 is 'intensifier' and the other 2 'not connected'. Question is what does the intensifier do?

[fagin]

Firstly... well done!

Secondly... when they have used a RED wire for any other video colour, other than red itself..... who the **** knows which Vsync and Hsync are, out of the black and grey wires!!!!!

With regards to what "itensifier" is...... I really wouldn't bother worrying about it.

Lol i know tell me about it, regarding the sync i have tried black in h sync and grey in v sync, and the opposite way around, and then either one just in the C sync and for the life of me cant see a difference really, so not sure whats going on with the sync and what way to set it up?

Shaun from my finds can you see an easy way for me to get the scart input working? From what i can see when using this input the colours are correct (thank fuck), but obviously this strange sync setup is whats causing the problem

[lettuce]

Bit of an update, i decided to make a Scart adaptor for the D9 socket seeing as i couldnt get the actual scart socket to work with any of my consoles, and didnt want to keep using the SS for this monitor.

I got some D9 male sockets, D9 housing, Scart to scart block, and some trailer wire. The Trailer wire is spot on as its 7 core so has enough wires for what i want.....



I dismantled the scart to scart block and unsoldered the wires.....



Striped and tinned the trailer wire and solder to the correct pins on the D9...



and lastly added a audio break out phono adaptor....



All placed back in the scart to scart case....



works like a champ!

[neorichieb1971]

Great job Lettuce. Fancy doing one for me? I've never seen my monitor in RGB

The little wobble is most likely corrected with with one of the options on the monitor itself. I did something on the XRGB2 once where an option stopped it wobbling a bit to give a rock steady image.

We should hook up sometime since your local. I live in the Goldington/Putnoe area along Norse road. I've got some cabinets and PCB's as bait hehe.


edit - Most of my scarts are JP21 which adds more confusion. I only have a supergun and Playstation scart wired for Euro.

Would still love one.. and would love to meet a fellow shmupper locally

[Jumpingbarrels]

Sorry for reviving this old thread but I have recently aquired the same Hantarex monitor and am struggling to get it working with my japanese super famicom. After google brought upshot post (and the others on arcadeotaku) I managed to get my SFC hooked up using the D9 connection, however I get a nice crisp image but the colours are all really dull! Could anyone help me please. The scart is hooked up to the D9 as lettuce did his?

Thanks

[neorichieb1971]

Took mine to the tidy tip years ago.

Its a shame though because the Hantarex had all the nice geometry adjustments on a menu.

[mvsfan]

i had an rgb nes i built that wouldnt sync. the problem turned out to be that pin 19 on the scart cable wasnt grounded.

[Jumpingbarrels]

I get dull colours through all inputs, scart, s-video, and the D9! Can anyone shed any light on why this is?

[lettuce]

A few suggestions, have you tried pushing the 'Analog/TTL-I' or the '75ohm' buttons or a combination of these
