Problems using a VGA splitter for Microscan


To split the signal from the MS Connect, I built a 6 foot long Y cable to connect 2- MS-9's or 820's to the MS Connect. This cable causes the MS Connect to treat the 2 scanners like 1. It works great but the 22 gauge cable with 24 wires is a bear to make. Many companies make a VGA splitter Y cable that is straight thru and combined with a standard Microscan HD15 extension cable seems to do the job. But, thru some hair pulling, the Y cable won't work with 2 MS-9's or and MS-9 and an 820.


Turns out that the VGA splitter cables are only 28 gauge. American Wire Gauge Table shows that a 28 gauge cable can only carry 226 milliamps and you need about 300. My 22 gauge cable will carry over 900. Contact us for more information on this and any other Microscan product.
