Device cable extensions
Extensions extensions extensions. Got some amazing devices you need
to connect and running into distance problems? Well here’s a list of
some common connection types and what you can do to extend them.
First we’ll start with USB extension cables. USB can only be
extended up to 15 feet unless you use some sort of active extender.
The passive 6 foot extension is great if you just need a few more
feet. You can see it here:
If you need to go further you can use the 16 foot USB 2.0 active
extension cable. This cable has a built in repeater that is self
powered by the USB bus. These can also be daisy chained to give you up
to an 80 foot extension.

Need some USB 1.1 ports a long ways away from your computer? You can
use a USB over CAT5 extender. This box will convert the usb connection
to common CAT5 ethernet cable. Then at the other end it will give you a
4 port USB 1.1 hub up to 150 feet away.

Now let’s look at some firewire extension cables. Firewire also has
the same limitation as USB, it can only be extended up to a 15 foot
cable unless you use an active extension.
We have a 14.5 foot active extension cable that is 6-pin male to
female. This cable also has a bus powered booster built into it (Note:
they must be plugged into a 6-pin firewire port on the pc for it to get
power. They do not work with 4-pin computer ports.) These can be daisy
chained up to a total of 60 feet. They are capable of running the
FireWire 400 speed.

If you need to go further, or want to power a device while plugging
into a 4-pin firewire port on your computer, you can use our firewire
repeaters. You can see Mark’s post about those here:

And for those of you that still have some important serial devices
kicking around let’s look at serial extensions.
Unlike firewire and USB, serial can be extended very far without any
boosters. We have extension cables from 6 feet to 100 feet. The 100
foot is shown here:

For those of you who want to use easy to run cat5 cable to run you
serial extension, you can use these serial to rj45 modulators.

There’s a great product for sharing a serial device with lots of
computers. And the great thing is it does it over a wireless network
connection. The adapter fully supports 64-bit and 128-bit WEP and WPA
wireless security standards.
