The iTach Flex Link Tri-Port Cable enables up to 3 iTach Emitters or 1 iTach Flex Link Blaster and 2 iTach Emitters to connect to the Global Port on an iTach Flex IP or iTach Flex Wi-Fi edition. This cable is not compatible with the iTach IP2IR or WF2IR. The iTach Flex is required. This cable is not equivalent to a splitter. iTach Emitters and the iTach Flex Link Blaster cables are separate items. Some configurations of the iTach Flex already include this cable. This item allows it to be ordered after an initial configuration that did not include it.
