If you want to control a Biamp USB 200 or a Neets USB switch from a control system, you won't find it in the device list. This product can be controlled by the I/O ports directly and should be added to your control system as an Output.
Find it here:
Biamp Project Designer (Version => 1.29.0) > Biamp > Digital inputs/outputs > Output
Neets Project Designer (Version < 1.29.0) > Neets > Digital inputs/outputs > Output
