Single Mitutoyo Gage to RS-232 Interface The GageWay SM is an easy-to-use interface designed to connect a single Mitutoyo digital gage (calipers, micrometers, digital indicators, etc.) to an RS-232 serial port. The GageWay SM interfaces also support any gage that provides a standard Mitutoyo output (CDI, Federal Maxum, etc.). This interface with RS-232 output is powered by the serial port and comes with a 9-pin serial cable, 18" in length, built in. Works with standard Mitutoyo SPC cables.
