thanks, but these topics where both the basic information for my project.
Why I'm trying to use the Betacam vwievfinder is, you can get them at eBay for about 100 Euro, the Canon b/w viwefinder is much more expensive.
As I wrote, the viewfinder works, but the image is not as it has to be.

Someone knows Specifications on FU-1000 fuse ?
 

My FU-1000 NTSC b/w viewfinder for the xl-1 has a burned fuse. does someone knows what are the exact specifications on the Fuse ?
Under it is written: F101
and right besides it A1,25 V125 (but thats not under the Fuse so im not sure if that belongs to the fuse).
a friend who is a tv mechanic guru would like to replace it but would like to know that first, so i try it here and on the canon service paralel (but we all know the service of big companies in those cases...)

regards

Elmar

The FU-1000 is actually manufactured by Ikegami for Canon.

You can download the product's manual and specs here.

Good luck.

Speculation: the notation you quoted implies 1.25 amps with a 125 volt interrupt rating.

thanks for the replies. the canon service said they cant say anything when the thing isnt in their repair agency but they can basically say that the numbers i told them are correct

B/W Viewfinder Question
 

I just ordered two B/W viewfinders for my cameras and just finished reading Ken's fine article about this device...however, I'm curious what the funtions of the four LEDs on the viewfinder body....I assume a tally light feature but what else?....:-)

Good for you, Mark. That was a pretty $ outlay but I think you'll be impressed.

Good question concerning those four little, red headlights. Answer: All four are tally lights. That is, they all flash together and have no other purpose. Go figure.

do they flash together or in sequence? I'm trying to figure out the significance of having four LEDs.....

They flash together. No Las Vegas effect. I've no idea why there are four. I think Ikegami made that design decision long before they retrofitted the viewfinder for the XL1.

Thanks for the info....also after reading your article on the manual lens, it confirmed my decision to order a couple of lenses for the cameras also. Big money spending day (along with an addtional XL1s). I just hope my 501 heads with handle the additional weight....

Aw, geez Mark. Whatever you do, stay away from my Firestore FS-3 article, at least until next month! And just ignore my upcoming article on the KinoFlo 12v lighting.

good point as my money supply has become exhausted.....

Is that FS-3 article up yet Ken? I would love to hear your opinion on it.

Thanks for the link Ken. Great write-up, especially the XL1 caveats. Despite those it is still a very tempting unit.

Sorry for taking this thread off topic :)

Ken,
Do you know how much (I imagine probably negligble) of additional current draw is there present with the tally lights on? Due to the high cost of outfitting two cameras with the viewfinder and manual lens, I haven't yet upgraded to a dual battery setup. However, I am using the -945 batteries and hopefully will give me some decent recording time.

I'm getting ready to use the new equipment for a wedding shoot this weekend and in the past I've had piece of mind when I look up in the balcony at my son as verify his cameras are indeed rolling.

"Do you know how much (I imagine probably negligble) of additional current draw is there present with the tally lights on?"

No I don't, but I wouldn't imagine it to be a significant battery draw.

FU-1000 Viewfinder Problem
 

Hello,
My Canon FU-1000 Viewfinder all of a sudden won't power on. It's connected properly to the XL1s and has a fully charged Canon battery connected to it. THe stock FU-500 works fine.
Please advise if anyone has any tips or tricks that I don't know about.
Thanks,
David Stapleton

It sounds like an internal fuse has blown. Another member encountered a similar problem not long ago. In his case the problem may have been related to using the camera on a/c power while using the FU-1000, something that the manual warns against.

Canon Service is your only alternative.

Thanks Ken for the quick reply. I'll post more info here for other users who may have similar issues once hear back from Canon.

yes i had that about a month ago. fuse burned. i replaced the fuse, its quite easy.
but i still have another problem. my picture rolls down very fast and gets slower and slower until it stands still but before it stands still it takes 5-10 minutes of rolling picture. my cam is pal but viewfinder is ntsc labled. looks like the syncronisation chip isnt able to syncronise correctly :-(

Were you somehow able to replace the fuse yourself or did you have to send it into Canon? If the former, how'd you do it? If the latter, what was Canon's turnaround time and how much did it cost?
Sorry to hear about the scrolling issue. Can Canon fix tthat for you?

no i cant fix the scrolling myself :-( when i would have a technical plan of the viewfinder i could give it to a friend who looks at it and could say me if he could do it himself. im not even sure if its a bug or just because its a ntsc labled version and i have a pal cam.
when its the fuse, you dont need to send it in when you dont have warranty for it anymore. its easy to fix. i havnt done it myself (cause i have 2 left hands) but my cousin did it and i watched it and he isnt a pro either (but knows how to do easy things).
open the adapter (not the viewfinder !) you will find written on the board F101 A1,25 V125, that the fuse you need to buy - 50 cent. then remove the old one (its over the written F101 and looks like a U but the other way round) and solder the new fuse in. et voila - working again. dont remove any cables while the viewfinder is on, it burns the fuse instantly.
but of course, youre doing it on your own risk, i just tell you what i did and it works for me ;-)
ask a friend who owns a solder thing and who has a bit knowledge using it and thats fine for the burned fuse.

Elmar

Great, thanks for the info.

How did you know that that fuse was blown to replace it. I'm looking at it now and it looks ok. I guess I don't know what I should be looking for.

Where did you find the fuse? I went to Radio Shack and they didn't have anything like it. I've scoured the web and found a "Zenith F101 Fuse" at Partsolver.com, but don't know if it's the one I'm looking for.

hmmmm... i dont know what it is called in the USA... we have big electroshops here who sell everything that amateur constructors need to build/fix.
im 100% sure you have something like that in the bigger cities or as internet shop. i dont know what the f101 is meaning, but it must be A1,25 V125 or compatible solder fuse

Could you tell by looking at the fuse that it was blown? If so, how?

no a friend used a measuring tool and measured the if energy flows. no energy flowed so the fuse was burned

Tripp,

The F101 is just a part designator number. It has nothing to do with the acutal fuse. The fuse rating you are looking for based on Elmar's reply is a 1.25 AMP 125V fuse. Since I don't own this viewfinder, I can't tell you what the fuse phyically looks like. Might be best to take the unit with you to Radio Shack and see if the store clerk can match it for you.

To check the fuse, un-solder one side and use a volt-ohm meter to check it. You can buy a cheap one at Radio Shack. It will have an analog meter that shows maximum resistance on the left side and minimum resistance on the right side. A small thumbwheel or knob allows you to 'zero' the meter while touching the meter leads to each other. Full scale deflection will change depending on the scale you select and the condition of the battery.

If you aren't comfortable un-soldering and soldering, get someone to help you. You can burn the traces off the printed circuit board if you overheat it.

FU-1000 Viewfinder...won't work with AB batteries?
 

I just read this in a customer review of Canon's FU-1000 B&W viewfinder;

"One of the most troublesome aspects of the unit is the necessity for the battery adapter which locks onto the XL1/XL1s in place of the battery, then your battery locks into that adapter. The adapter is EXTREMELY sensitive and does not tolerate anything but Canon batteries. I ended up sending mine in for warranty service after the very first time I used it in the field as it had stopped powering the viewfinder completely. The techs tell me that the AC adapter and most third power batteries (including the Anton Bauer QR-XL1C) cause the battery contacts' connections to the board to overheat and burn-out."

Is this true, or for that matter a common occurence? Any opinions would be great as I was planning on getting the viewfinder for my XL2 with Anton Bauer setup.

thanks,

Oliver

Oliver, I've moved your thread from the XL2 forum to the XL1
forum since there are a lot more people here who have experience
with the FU-1000 than over in the XL2 forum.

thanks Rob, my only concern though was that perhaps compatibility issues between the XL1/S and the viewfinder might be different than with the XL2, and so it would make more sense to post in the forum relevant to my camera.

thanks,

Oliver

It is the same viewfinder, you are correct in that it is attached a
slight bit different to the XL2 (the XL2 has a special port for the
FU-1000, which I think is for the power).

Yes, the FU-1000 runs on 9v, so the adaptor steps up the nominal 7.2v XL series battery to provide this voltage. The multiple pins also provide a variety of other functions of the viewfinder (tally light indicator etc). I'm still trying to isolate which wire does which for a mod I'm making--anyone that can locate a wiring diagram, please chime in!

The XL2 does away with the nonsense of the adaptor by providing a built-in jack that directly services the FU-1000 and provides it power, video and the other functions.

Great thanks guys. So just to confirm:

XL2
+
FU-1000
+
Anton Bauer batteries
=
no problems?


thanks,

Oliver

Canon Reps will tell you that any use of "Non Canon" power supply will void the warranty if you have a problem. That's the official line. I know, I just heard it.

The FU 1000 has it's own plug on the XL2, seperate from the color viewfinder port. This is better than the xl1 because it frees up the battery compartment so you can use the AC adapter.

I was using AC to power my viewfinder and it did burn out, luckily it was still under waranty and was repaired.

Dan,

I seem to recall an earlier thread here discussing that same problem. If memory serves correctly, it was stated that you can't run the FU-1000 off of the AC adapter for the very reason you experienced. Supposedly, there is a warning against doing this in the Canon docs somewhere.

I don't believe this applies to the XL-2.

=gb=

Page 15 of the Canon Monochrome CRT Viewfinder Unit FU-1000 owners manual I recieved with my FU-1000 viewfinder:

Notes on using the FU-1000

"The FU-1000 cannot be powered from an AC/mains outlet (with the CA-900/CA-910 Compact Power Adapter) or from your car battery (with the CB-900/CB910 Car Batery Adapter). You must use a batery pack (or two with the CH-900/CH-910 Dual Batery Charger/Holder* (sold separately) to power and use the FU-1000."

Hope that helps

Dan

That's interesting, Dan. I'm now wondering if this limitation does, in fact, apply to the XL-2. I don't have the FU-1000 yet but I would think with the native plug in support for the B/W that the XL-2 is ok. I know the XL-2 supports an extra contact in the battery compartment which is only activated when the AC adapter is attached. It cuts off the battery level display in the viewfinder but it might also be used to let the camera know how to differenty handle the B/W VF if present.

Perhaps someone with XL-2 and B/W VF can check this out.

Nonochrome viewfinder questions
 

After reading numerous posts, and reading Ken Tanaka's thorough review at-
http://www.dvinfo.net/canon/articles/article83.php, I ordered the fu-1000 viewfinder. I've been having some focus problems, mainly indoors and in lower light conditions, under chaotic conditions.We've been doing some shooting for a local pol running for sate senate, and the conditions have been pretty bad. I'm hoping that my 57 year old eyes will have an easier time with the fu-1000.
Have any of you used it in run and gun type situations? Under what conditions has it been most helpfull? Since there is no battery status info, does anyone have any idea of how long a Canon 945 will typically last? ( I have an AB dionic 90 also, but was wondering about the stock batteries usage.)

Thanks in advance for any help.
