This cable has incredibly limited applications. All TZTouch3 displays come with a 10-pin to 12-pin adapter cable. The only time the MMC-12F-L cable should be used is when a single, single-frequency Low transducer, is being taken to one display, and the purchaser has chosen not to use the 10-pin to 12-pin adapter cable. We would strongly recommend qualifying the application for any sale where this cable is being purchased.
