Title: USB Cord
Post by: Eddie B on March 29, 2011, 01:24:10 PM

I need to connect a comercial DVR to a computer VIA USB, A connection from a Port on the DVR to a port on a computer. Therefore I need a USB connecting cord. I see in catologs and on line USB cords with a  type A connector on one end and a  type B connector on the other end. What does type A and Type B mean ? Do they fit into either port and are the internal connections the same?

Yes, USB connections have standards, A, B, Mini, Micro and a few other lesser known ones.

From your description, The cord you have seen is one of these:

Any local computer shop should sell them for under $10. Just ask them for a USB male A to USB male B connector :)
Or e-bay, or other local online auction site.

Is this the connector your DVR uses?

Thanks Kurtiskain, that was very informative and clear.   I also just ordered the computer desk top encylopedia that you used in your illustration. Problem solved!!!

The USB type A and B connectors were the original standards, and the most common types.  However with the minis and micros, mostly used by cameras and MP3 players, there seems to be little standardization so you need to be careful if buying a cord for them.  Some of the minis and micros that look identical from a distance don't fit into the jack.
