Control two devices with RS232 splitter

[peppecantarella]

Dear all. I made a VI that control (a part from many other things)  a PI stage and a Thorlab shutter. The problem is that both need an RS232 connection and my computer has only one port. 

I bought an RS232 Splitter and now both are connected but once the first enstablish a connection the second doesn't. Do you have any idea of what I am doing wrong? Is anyone already done something similar? The two devices have different baudrate but the problem is that running the "initialization" VI for both, if I establish a connection with the first (using the correct parameter), the second won't work (even if the parameter are correct). I think that the problem is on some sort of conflict in the port but I don't know how to solve it.

Thanks

Don't use a splitter. That makes no sense. You should have multiple USB ports that you connect dedicated converters to.

Thanks for your answer, I'll try this solution and I'll let you know.

"Don't use a splitter. That makes no sense. You should have multiple USB ports that you connect dedicated converters to."

Or one USB port feeding a 2 or 4 port RS232 converter. 

(same end result, but somewhat cheaper and cuts down a bit on cable/device clutter)

It does work! thanks
