Today, you need to connect to them with different computers. Each computer will need to select which radio it connects to. This goes for SmartSDR-Windows, CAT and DAX. We have this problem in spades in our office since we have 5-20 radios on the network at any given time. The solution we use here is to tell the Windows programs which radios to show by placing a file named filter.txt in %appdata%\FlexRadio Systems directory. You can create this file with notepad, etc. and then save it to that directory. The file will need to contain full or partial serial numbers of radios that you want to connect to from the computer where you place the file. Generally, the file will contain one serial number on each computer. I generally just use the last 4 digits of the S/N since they are typically unique.
