Control two devices with RS232 splitter

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
