NEW in box Global Cache Flex Link Serial Cable RS232. Connects to the iTach Flex Module with a 3.5mm jack to IP/WiFi control for serial components. The cable will automatically detect whether you need a crossover or straight-through connection, and then switches to fit your application. Comes with an additional adapter to fit your needs. Box was opened to take photos only. I have others as well that are still factory sealed, as I have more than one for sale.
