Hi everyone,

I am using DI-149 USB Data Acquisition Starter Kit which will be connected to my PC through the USB port, what if I want to have LONG DISTANCE data acquisition system and by long distance I mean instead of having the short wire that comes with device, I want to use longer wire or using different protocol. I am working in oil and gas site and the AC power is not allowed ( I cant use my PC ) so I need to have a wire of minimum 1 KM to provide safe data logging.

thanks : )))

Hello Sabirmgd,
 
I assume that you need to be able to view real-time data? Is stand-alone data acquisition not an option?

An active USB extension cable might get you an extra 100 ft. or so.

See our blog post on the subject at:
http://www.dataq.com/blog/faqs/active-usb-extension-cables-limit-data-loss/

An Ethernet connected data acquisition instruments would be a better choice in this circumstance.

You might consider a product like the DI-710-EH. Using hubs, you could stretch an Ethernet cable as far as you'd like. You could even record data over a local area network, or via the Internet. The power requirement id 9 to 36VDC, 2.5 watts max.

For more on the DI-710-UH, go to:

To discuss your application further, call (330) 668-1444 and ask to speak with someone in sales.

thanks for the response Mr Shawn,

the thing is, the DI-149 USB is already there and under the current circumstances, the task is supposed to be done within the available resources.

how about extending or having multiple An active USB extension cables connected together? will it work ? or even using any other communication protocol ,like rs485, that can be added on the DI-149 USB ?

thanks

Sabirmgd,

In theory, you could use multiple active USB extension cables.

I'm not aware of any customers using USB connected instruments over such great distances, however. So I cannot say for certain whether or not this will work.

See http://www.icron.com/products/icron-brand/usb-extenders/fiber/usb-2-0-ranger-2244/ for a fiber optic USB extender that would probably work but be too expensive.
