From VGA to BNC
 

I'm planning to buy the Xenarc 7" but I want to connect it through BNC. Is there a way I can connect a single BNC cable coming from my camera to the Xenarc VGA input?

Thanks,

Guess nobody knows?

A simple cable adapter is not sufficient to convert BNC to VGA.

What signal is on the BNC cable. Is it composite, SDI, HD-SDI, etc.?

Depending on the signal, you may be able to find a electronic converted that will drive a VGA monitor. BlackMagic Design may have what you need.

I found this website:

would it be sufficient to buy this cable so I can connect an LCD screen like one of Xenarc to my camcorder with s-video out?

Thx,

Sorry, but no.

The full description is here:

This adapter takes a VGA adapter card with TV-Out and provides a composite video output jack and/or a S-Video output jack.

The following is from their website:

VIDEO Card to S. Video and TV Adapter Cable

Connector: VGA(HD15) Male to S-Video Female and RCA(Composite) Jack
Cable: UL 2919 Coaxial Low Voltage Cable

(*)It will work with VGA cards that has TV-Out function capability through the VGA connector.
Check your Video Card manual or manufacturer to make sure that your VGA card has TV-Out function capability.

So there isn't a way I can use a monitor from Xenarc as a video assist with my FX1?
I'm sry if this sounds like a stupid question!

What signal are you trying to connect to the monitor?

The Sony FX1 has composite out, S-Video out, and component out.

I may be mistaken, but from the manual, none appear to be using BNC connectors.

What inputs are there available on your Xenarc? Which model Xenarc do you have?

check this thread.

Mmm intresting, specially when I'm going to use the Xenarc (which I didn't buy yet) for focussing and framing.
I found out that the Xenarc 700YV also has RCA so I could make a connection.
Do you think you could compare this with the Varizoom TFT7? Both connect to the camera trough RCA while the Xenarc has a higher resolution then the Varizoom.

Thx again ;)

xenarc monitor and FX-1
 

The only way you can use that monitor at full resolution is to take the component RGB out and convert it to VGA through an electronic box. Details of this conversion I have posted before on this site- do a search for Xenarc. This is the only way you can use that monitor for accurate focusing. If you a fine with not so good focusing but at least performance/framing capability then you can just hook the camera up directly to the RCA input on the monitor via your RCA output. But be aware that it is then a composite, standard definition signal and no longer hi-def.

sorry to disagree, keith, but what you said isn't exactly true. RGB and VGA are both analog signals, so, no converter box is necessary. All you need is a converter cable, VGA on one end and 3 component RCA's on the other. I do it all the time to inject component out on my camera to a 21 inch LCD screen.

So actually I can buy this: http://www.virtualinformation.com/eb...es/vga-1lg.jpg

And then connect it to my s-video out, and the VGA from the Xenarc?

VGA vs. RCA
 

Certainly you can convert the end of the cable - I was advising on how to get an HD image out of that camera- The S video image is not Hi-def and neither is the RCA out of that camera or any other HDV camera on the market. The only way you get HD resolution out is through the three component analog signals. If you plug those directly into a converter cable to VGA then you can only get an image on a VGA monitor if it supports the specific resolution the camera is giving, if it has built in scaling capability, if it has multiple ground syncing capability, and if it can handle the individual Hrz frequencies on the three signals + ground sync. In my experience there are very few small LCD monitors out there that can do this- the Xenarc being the exception. Many larger monitors however do have such capabilities though most of them now are offering direct component in, so it makes this conversion all unecessary. Anyway I was advising on adapting for the small LCD which this forum started out with. By the way- I have tried plugging the Xenarc 7" directly with the converter cable only and it does not work because the sync is out of range even though the xenarc does have extensive built-in scaling. The converter box I use by audio authority effectively controls the ground sync (though not perfectly because there is a green shift) and puts it in range for the monitor to accept the signal.

Hello Keith,
I am trying to connect my xenarc to HVX via component out > Mayflash VGA transcoder > Xenarc. I can get a decent image when I connect the av cables and select av1 on the monitor; However, when I try to run the comp>vga adapter>monitor set up I don't get a picture on av1,av2, or PC (or anywhere). What am I missing? Is there a setup menu issue here to get the component out to work or should it work as soon as the cable is plugged in? Would appreciate some help.

Probably redundant, but did you plug in the power of the mayflash? It might work without power on SD and only with power on HD. Just a thought.

Steven

Yes, I plugged in the power.
Do I need to be in P2 mode with a p2 plugged in (or firestore) in order for the camera to be sending out a signal through the component out? It seems as though I should get a signal just with power on in standby.

I thought that I would try to troubleshoot by bypassing the mayflash. Is there a way to do this? Perhaps a cable (D4 or something) that will get me from comp out to the 20-pin VGA plug that goes into the xenarc?

I ordered the vga001 and a mm400 screen (for the canon a1), so hopefully I'll soon be able to test this setup and see what my results will be...

That would be great!
Where did you ordered your VGA001?? Cause I live in Belgium so the shipping will be the same!

They have very low shipping, and they were quite fast processing the order. I should have it shortly!

VGA has analog RGB running over a DB15 connector, but most HDTVs take YUV over the same DB15 connector. Converting between RGB and YUV is not incredibly difficult, but it does require amplifier circuitry.

The Xenarc does accept an RCA/component input that converts directly (with a straight-through adapter) to BNC or S-Video.

You can connect the BNC to the RCA input with a cheap adapter ~$5 at radio shack.

bnc to vga
 

I am new to these boards, and I have a question. Maybe someone can help. I have an 8 channel DVR with BNC outputs. I need to connect the DVR to a flat screen monitor with only a VGA input. Where is the best place to buy a BNC to VGA converter?

Thanks

Dear Wayne,

Your question is hard to answer.

Could you please supply a model number and the manufacturer's name. A website for the manufacturer would be nice also.

I assume that your 8-Channel DVR is for video surveillance and you have 8 channels of video inputs via BNC connectors (and not 8 BNC outputs).

If you have BNC output, we need to know what signal is on the BNC output connector. It is probably "Composite".

So, we just need a little more info to answer your question.

vga to bnc
 

Dan,

Your assumption is correct. There are 8 BNC inputs which all have cctv cameras attached. I believe the output is composite. I am not sure of the manufacturer. The customer bought this DVR off the internet. It could be "look see" dvr, although I don't believe the manufacturer would have much to do with it. This application should apply to any DVR that has multiple cameras connected and the user wants to view the output (bnc) on a vga monitor.

Thanks,
Wayne

Ok, So it appears that you have a composite output, on BNC.

It is easy and cheap to get a BNC to RCA adapter so that you can use any monitor that is capable of handling composite.

Your specific VGA monitor probably does not have a composite input.

So, you could get a new monitor or there may be a composite to VGA adapter. These may exist, but I have never searched for one. Maybe someone else knows.
