The Pangolin FB3-QS laser controller is a small, palm-sized box connects between a USB port on your PC and the ILDA input connector on your laser projector.

FB3-QS can use up to 500 mili-ampere which means that when you use an USB hub to connect the FB3-QS to your computer, make sure that you use a powered USB hub.

Dimensions : 4.2 x 2.8 x 1.3 in (110 x 71 x 33 mm)

Extending USB over Cat5

Pangolin has tested over 50 different kinds of USB extenders (not kidding) and various USB server/client setups. None of them fully worked with FB3-QS series controllers, except for one:

Note that this is not an USB over IP device!

The local and remote devices are connected by standard CAT5 or CAT6 (network) cables, They use their own proprietary protocol, so you need to use it one on one (You cannot put a switch or hub in between). The remote device supports maximum 4 USB devices. The the original adapter is strong enough to power 4 FB3-QS.

There are 3 similar devices from this company (single, dual and quad port versions). They all should work equally well, but we only tested the quad port version.
