Hopefully, most questions you might have about laser shows and equipment are
answered in the various product, pricing and informational pages in this
website. Below are listed some infrequent questions that you might find

Running two projectors from one QM2000 board
Is it possible to split the serial output of the Lasershow Designer
QM2000 card to run two separate projectors simultaneously off of one card,
or will there be protocol problems.( has this been done to your knowledge)
It depends on what you mean by "serial output". Do you mean the
analog output (X, Y, colors) which controls the graphics portion of the
projector, or do you mean the DMX-512 output which can control lights, beam
projectors and other accessories?
If you are referring to the
analog graphics output, it depends on the distance that needs to be driven.
If the cables are relatively short, perhaps up to 25 feet each, you should
be able to take the analog signals and tie them to both cables. For longer
cable lengths, it is desirable to have two separate distribution amplifiers
to drive each cable segment.
If you are referring to the DMX
output, you definitely SHOULD NOT tie the output to two cables. DMX devices
usually have an "input" and an "output" connector. If
you have two devices, you connect the output of the QM2000 to the input of
the first device, then connect the output of the first device to the input
of the second device. With DMX, the total cable length can be up to 4000
feet so this generally should not be a problem.
