[AG-TECH] Tandberg Control panel

Can some one suggest a vendor for getting the Camera control software and
the visca cables. Can we daisy chain these cameras and connect them all
to a single port ? If yes, do we use any separate cables for daisy chaining.
(I see VISCA IN and OUT, so possibly we can daisy chain them).
