Ethernet and Mini-USB Ports
The NXD-430 and NXD-435 have no power input port. Instead, all power is supplied via the Power over
Ethernet (PoE) protocol. With PoE, the power is supplied directly through the Ethernet port through the PS-
POE-AF PoE Injector, available from AMX. For more information on the PS-POE-AF POE Injector, please
refer to the PS-POE-AF PoE Injector section on page 17.
The mini-USB port is used solely for programming the touch panel. For more information on software
upgrading, please refer to the Upgrading the Firmware via the USB port section on page 39.
Capacitive Touch Buttons
Unlike other touch panels, the NXD-430 and NXD-435 utilize capacitive touch buttons, where the button
reacts with the electrical conductivity of the user's skin. This allows the touch panel to be used in situations
where excessive humidity might affect the function of standard touch panel buttons. This also allows the
button to resist wear and dirt, as this button does not have any actual physical button to depress.
Each button has one green LED above it, which lights when the button makes contact.
Because of the behavior of capacitive touch, the buttons do not require hard pressing
to get a response. A touch that includes as much skin surface area as possible, such
as the whole of the thumb, works better than hard pressing.
The NXD-430 has one large capacitive touch button and the NXD-435 has one large button and four smaller
buttons, all on the front of the device. The main large button, known as the Front Setup Access button, has
several uses:
The additional buttons on the NXD-435 may be programmed for individual functions. These buttons must be
programmed for functionality through TPDesign 4, and cannot be programmed through the touch panel.

Press the button once to start a previously programmed function, or to turn off the display if not
previously programmed.
Press and hold the button for 6 seconds to put the device into Setup Mode (please see the
Status section on page 45 for more information).
Press and hold the button for 9 seconds to enter Calibration Mode (please see the Panel
Calibration section on page 19 for more information).
Press and hold the button for 20 seconds to reboot the panel.
