GagePort Power Supply 220V The GagePort Power Supply is required for use with either a GagePort or a GagePort Multiplexer. This 220v GagePort Power Supply is required for European and Asian countries that do not use the American 110v power. The GagePort Power Supply also provides the connection between the GagePort or GagePort MultiPlexer to a PC's 9-pin serial port. This is the correct power supply to interface the GagePorts with most SPC software packages, or software Win-Wedge. Note... This power supply should not be used with GagePorts to VisualSPC / Proficy SPC Software. You will want to use the A-681 GagePort Power Supply. This Power Supply contains lead.
