Introduction

NXD-430/435/435P 4.3” Wall/Flush Mount Touch Panels

Side Connectors

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, refer to the PS-POE-AF PoE Injector section on page 19.

The mini-USB port is used solely for programming the touch panel. For more information on

software upgrading, refer to the Upgrading the Firmware via the USB port section on page 41.

Capacitive Touch Buttons

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.

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.

Front Setup Access Button

The main large button, known as the Front Setup Access button, has several uses:

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

Setup section on page 47 for more information).

Press and hold the button for 9 seconds to enter Calibration Mode (please see the Panel

Calibration section on page 21 for more information).

Press and hold the button for 20 seconds to reboot the panel.

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.

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.
