The PT-4iREX is an IR signal repeater that can function at
distances up to approximately 75 meters (240 feet) and you
can use with all wireless IR signals. The unit routes IR
signals in places where there is no direct line-of-sight for
standard IR signal function. You can rackmount four (4) units
side-by-side in a 1U rack space together with the optional RK-
4PT rack adapter.
