Bob – I get most of my cables and splitters from www.cablewholesale.com. Here’s a link to a DB9 splitter: www.cablewholesale.com/specs/db9-splitter/30d1-27208.htm And here’s a link to a DB15HD splitter: www.cablewholesale.com/specs/vga-splitter-cable/10h1-27708.htm These splitters have all pins connected through.
