Ive heard the topfields component output isn't hsa good as the RGB out put.

So I'm wonder how I can get the SCART RGB into an NEC plasma. I have either a BNC (R, G, B, H/CS, V) input or mini D-sub 15 pin, I think the former would work.

So how do I put the two together?

Para6....please advise if your NEC is SD or HD as this makes a big difference in you accessing its RGB for the Toppy.
After you tell that i can let you know your best options...

Yea it's HD,

to start with, the only thing that is not quite right on the Toppy is the component output so it pays to use RGB one way or another.....
The Toppy cannot supply both vertical and horizontal sync....the SD only needs 1 sync and it is easy to set up... the HD needs two...there is no Way to set up the NEC with one sync, therefore you cannot access the RGB connectors on the NEC...however the Cypress RGB to component converter does a lossless RGB to component conversion and allows you to plug component direct to the NEC or via an A/V unit in conjunction with other component units...The Cypress converter supplies a signal that allows the plasma to run its colours at default.Toppy standard component requires colour manipulation....Cypress is by far the easiest way...this has been posted to death in the past and many ways tried...and it always comes back to folks using the Cypress converter supplied by Hantrex...and it is the method I use for both of my Toppies via my A/V unit...i have 2 cypress units.....I am 110% happy,
If you have any q's i can answer them for you.

Yes Paranoid666au, you are right it should work with the BNC connectors.

All you need is a simple cable/adaptor that will take the SCART cable signal and provide you with R, G, B and Composite sync.

The Toppy can only output SD, so you better make sure that your plasma can accept SD video level signals.

If you are unsure, I would suggest that you purchase from Dick Smith and preserve all receipts and packaging in a good condition. If it does not work for some reason, you will find their return policy handy.

Peter...If you read my post you would have seen that I said the NEC HD unit needs vertical and horizontal sync to display HD and Sd via the BNC connectors...also the option for a single sync is not there for the HD version,,,only for the SD NEC...the Toppy does not supply this successfully for the NEC HD...iThe Toppy supplies 1 sync to the SD NEC, and that is composite video to a choice of 3 connectors but the Toppy cannot supply 2 syncs successfully to the HD NEC,
Peter It beats my why you continue to ignore what I post and just post over it as if I have not posted..99% of my posts are accurate, and this is one of the 99%....All of this has been gone through before...any HD Marantz owner or NEC HD owner can confirm this,,,Mark Haines had gone through this as well...Pg 24 or 25 of the NEC manual is different for the HD than the SD manual.one of the only differences....the option for a single sync is not there for the HD NEC....
We have even compared manuals over the phone with another HD owner.
It should be enough for me to say it with out going into intricate detail why it won't work
it needs 2 syncs...the Toppy does not supply a second sync at the correct voltage n..
...unless something dramatic has changed or a custom cable for dsub has been wokrd ot...one member spent 250 dollars for a cable which failed
I can access the Toppy via the BNC RGB connectors using composite sync, either to video 1 BNc or either H or V BNC on my SD NEC,,,,but HD NEC owners cannot use a single composite sync. thats a fact


Having said all of that the easiest and most successful and lossless way to convert RGB to component is with the Cypress converter...there may be other ways but not lossless

As I mentioned in this post (RF Design Cable), I have used this cable (US$80) successfully with my SD NEC plasma.

I think it produces the required H & V sync signals you require, but connects to the generally unused d-sub connector freeing up your other inputs (assuming the HD NEC has a d-sub input).

Haggis

Sorry, Foss ... but you are very wrong this time!! The Toppy works BEAUTIFULLY with the NEC HD panels (both 42" and 50") via RGBS (onto 4 of the 5 BNCs) or RGsB (via the DB-15 XGA input).

Paranoid ... all you need for RGBS to the NEC (the best connection) is a 'Crest' metal SCART->RGB adapter ($20-30 at HN), a decent set of Component video cables, a decent Composite video cable and 4 RCA->BNC adapters (about $3 each at Jaycar). Run the Component video cables from the SCART adapter to the first 3 BNCs, run the Composite video cable from Toppy 'Video out' to the 4th BNC, then set the NEC's BNC-Input type to SCART1 (RGB plus Composite Synch).

This gives an outstanding PQ on the NEC HD panels from the Toppy.

Cheers,
Ian

If you read the original post carefully, you will see that Paranoid666au clearly stated that the BNC connectors support RGB with composite sync. The Toppy has that available on the SCART connector. The only potential issue is whether it's TTL or video, but given that the connectors are BNC, you can be 99% sure it will be video levels. The only outstanding detail to figure out then, is whether the BNC connectors need to be terminated. Given that they are inputs into a display device, I would bet $5 on the fact that they are either terminated correctly or there is a switch to turn termination on and off.

All in all a pretty good chance it will work with straight through cabling - just get the right type of connector on each end.

OK, thanx for all that guys.

So I'll get a SCART to RCA componet adapter. Component cable and single RCA to RCA cable, is the quality of that important?

Hi...and oops....
Here are some ideas and reasons for doing what I have got setup...and the reason why I posted what I did earlier...It is all due to what connections were available on what model NEC's, so while I am wrong re the current models, I was right with regard to the timeframe I was involved with and referring to...only about 6 months ago!!!

I should have realised that NEC would not stand still on that point...the setting you describe as being available now, was not available for HD NEC's and HD Marantz back then, and the HD NEC needed 2 syncs...so while I was correct with regard to the older NEC's I am not correct for the Later model HD NECs....I have always been able to do what you describe, but that option was not available for the HD then and was missing from the manual when we compared the page ....page 25 I think it was...

It seems as if NEC have updated their HD sync connection requirement and have made it the same as my SD NEC which by the way gives a beautiful picture from the prescribed viewing distance of 12 ft... a...when Mark(I think it was Mark Haines) and I were researching and comparing the abilities of the SD and HD panels, both vertical and horizontal sync was needed for HD panels at that time...
At that time...some months ago now, I was able to run a scart cable to the RCA converters I had attached to the BNC connectors...I was able to connect composite video Sync either to the BNC video 1 or one of the other BNC connectors that were not labeled RGB...and then select Scart type 1...that selection was not available in the manual of the HD version of the time frame...It appears they have changed that now...

so I apologise for assuming that NEC had not improved their HD RGB connectivity so that it needed only 1 sync...
In the long run I am doing things a different way to make it a 1 button remote press to access my A/V components

As a suggestion.... if you have other devices connected to your panel via component through your A/V unit, it is worthwhile running the Cypress converter so that all connections run through the A/V unit..it saves fiddling with sound and selecting the RGB input on the Plasma, if you operate more than one box or more than 1 type of video input.

For example, I dont have my plasma RGB connected (even though I could have)...I have my 2 Toppies outputting RGB and converted to component, then I have the two Toppies running through the A/V unit as component and also I run my component DVD player and another component unit all via the A/V component unit....so what that means is that I just press any 1 of 4 buttons on my A/V remote and the sound and picture for that component are displayed and played at the same colour and sound levels of every other component...Some A/V units have multiple RGB's but mine is a mid range unit and has multiple component inputs...so I went that road,,,

With a button press along the top row of my programmable remote, I can access either Toppy 1, Toppy 2, a Samsung HDD recorder or a DVD player....They are all connected with optical sound and either quality component or converted RGB to component...

Once I have the plasma turned on thats all that has to happen...the rest are controlled by one button push which then sets the remote so that I can control those Items with the same remote
It is difficult to explain everything, but suffice it to say that my setup, despite its complexity is very easy to operate. I realise I am not alone here with the simple operating complex setup, but I did it all myself...and its dead easy...
If for example I used RGb I could not have done it...or if I used the Toppy component, only one Toppy was converted and the colour output would be different with all units...annoying

So ijd ...assuming Para has the latest model averything should be fine...if he has my vintageNec and the HD model, the single sync will not work....I am 100 % wrong with regard to the current model and 100% correct with regard to the model I was refferring to...I should have stipulated which vintage i was talking about and there would be no confusion.
foss

PS Haggis...For example for me to connect RGB to my NEC, what you describe was not necessary ...All I had to do was run an RCA lead from Toppy composite sync to Video 1 in on the Plasma and run a scart cable from the Toppy to the BNC connectors (with RCA converters on them)on the NEC and select mode Scart 2 ..IE RGB and composite sync
foss

Maybey I should have geven the model number as well as the specs.

PX-50XM4

You can still do this with the latest NEC's, Foss ... but it does tie up the Video1 Composite BNC input/output.
The 5 RGB2 BNCs can be configured for YUV (3 BNCs used), RGBS (4 BNCs used) or RGBHV (5 BNCs used). Note: apparently no RGsB via the BNCs, though I haven't tried it.
The DB-15 input can be configured for RGsB, RGBS or RGBHV.

Well after reading all that (after 2 bourbons - mind you) I'm unsure if I should connect my Toppy to the NEC via the BNC's or D-Sub. I didn't think the D-sub was an option until now.

I was thinking of a SCART to 5 RCA(RGB +L&R) 3m lead plus a 3m composite video lead.

Is that the go?

Pardon me for butting in here, I've heard of (and understand) about RGBHV, RGBS, but never RGsB. Could you please enlighten me to this one?

Many thanx!

(OOPS: Never mind, worked it out - sync signal on the green signal line. I'm such a 'tard at times........ )

Foss,

I'm new to all this stuff, particularly in regards to BNC and SCART connectors. I've just picked up a second hand NEC 42" Plasma, model 42MP3 - which is running nicely - though I'm running it of a crappy Nintaus SD STB.

The plasma is HD, and I'm looking at getting a Toppy MP (although people have said for PQ I'm better off getting a HD STB, even for SD broadcasts...) - does your research above regarding the Horiz and Vert synch apply to the plasma I have.

I'd like to keep the component inputs for my DVD, although the screen also provides DVI and S-Video.

Thanks,

Rodders.
