Connecting to a Master Controller via USB

NOTE: With AMX's NX Series Controllers (NX-1200, NX-2200, NX-3200 and NX-4200), the USB Gadget Serial driver will need to be installed differently for users running the Windows 8.X 32/64 bit Operating Systems. This driver is required to connect to the USB programming port on the front panel of the NX Series Controllers. Manual installation of this driver will require the user to "Disable Driver Signature Verification" when installing unsigned drivers. Refer to the

Appendix: Installing the USB Gadget Serial Driver

(Windows 8) on page 204

for instructions on disabling driver signature verification and how to install the USB Gadget Serial driver.
