Programmatically Finding Connected cDAQ Units

I've currently got a solution to my problem, but it's not very efficient! I have a single laptop that can connect to 12+ cDAQ units by Ethernet cable (local only, the cDAQ's aren't on a network). I'm currently using the below snippet to try and reserve the chassis to detect if it is present, if it isn't move on to the next one, if it is, output the now reserved chassis name to be used elsewhere. Whilst this solution works, and it works every time, if I plug in to the 12th chassis, I have to wait for every single Chassis before to attempt a reservation:

Is there a better way of doing this? It takes about 8 seconds for MAX to try and reserve a cDAQ before the error is created, nearly 2 minutes for the 12th cDAQ to actually get reserved.

I'm thinking that if this is the best way of doing this, then I'll at least write the cDAQ name to file and try it first next time before starting looping as I can't have the end user waiting for so long everytime they wan't to connect to their machine.

Thanks
