There is also a schematic on the Steppir Yahoo group site 
http://groups.yahoo.com/group/SteppIR/files/ titled Y-cable.pdf and 
stamped by Fluid Motion that indicates that you can indeed Y the serial 
hoookup.
Of course, you'll have to wire your own DB-9(s).

It only has a 2 wire connection to the SteppIR controller. This is the 
scheme I'm planning on trying when the SteppIR goes back up.

Am I barking up the wrong tower?
