I am trying to get a tethered setup going as long as possible.

The minimum is 25' for my setup. Anything longer would be nice.

Is there a maximum distance for the USB in which it can transmit? If I link multiple cables together, would it start getting a lack of signal? The longest cable I have found so far is 25' mini USB to USB .


Also, what about a netbook with battery life over 8-10 hours? Anyone have any recommendations for one which can also run Canon DPP for tethering? As I understand, DPP requires 768 resolution. Aren't there ways to fake the higher resolution?

I'm looking at the ASUS UL30Vt X1K - Core 2 Duo 1.3 GHz - 13.3″ notebook, as it has 768 and long 10+ hours battery. Is there anything smaller? Or is this as small as I can go with retaining resolution and batter life?

Thanks for any help you can provide!

I transmitted via a 25' cable to my MBP and then directly out to a external hard drive. Not a single problem.

15 feet is the recommended lenght unless you connect it to a powered hub or powered extender.

And I just bought a Asus similar to what you describe for my wife.....getting about 7-8 hours of use (web, office.....light stuff) on a charge.

Cool, thanks for the feedback guys, I found the info I needed.

I will probably buy several extra batteries for the notebook just in case.

I plan on doing some BBC planet earth style setups and need to retain the control of the tethering, but gain as much distance as possible.

I looked, but are there no wireless setups that allow camera exposure controls along with live viewing?


I'm getting a little too OT, but what about wireless controlled 2-3 axis camera gimbals? A buddy at work apparently makes the best ones for RC planes and helicopters, but they cost $2500. His are called Triax or something like that. Hope to not have to spend that much, as I don't need stabilization.

I found this extender which claims 150 feet.

I gains power from both ends. Would the camera provide the necessary power in this setup? OR do I need something different? I need to be able to use this out in the woods, so no AC power will be available.

Check monoprice. There are a couple of USB extenders towards the bottom of the page.

Damn, that's just the ticket!

Sweet! I think I've got a bunch of ethernet cable lying around somewhere. 150 feet would be super sweet. Although that distance will probably drop a lot once I use it in the cold weather.

This is going to be one heck of a sweet setup! The only missing link now, is finding a decently cheap 3 axis gimbal, or just sucking it up and buying the $2500 one which is super lightweight and autoservo stabilized.

Also, what about a netbook with battery life over 8-10 hours?

You might replace your netbook/laptop "classic" HDD with a SSD.The best ones (Mushkin,G-Skill) aren't cheap but they make a big difference,energy consuming-wise as well as working speed.
Also,you might want to shut off or limit some of the netbook's hardware (e.g. WiFi) if you really don't need them at a given moment...this shall prolong your battery life even more.
HTH!

Use this USB Super Booster Cat5 Extender and you can extend your tether 150'. I use it and it works as claimed. 150ft might be pushing it, I use mine with 100' cat 5 cord and have no problems whatsoever.
Also, for your Asus UL30Vt X1K make sure to get an extra extended battery,here's one and you won't have to worry about running out of power.

you will not see any lack in speed unless you get an extension over 100m
