In-Wall
Blend your flush-mount touchpanel into the wall and make it a central point for controlling your home or business.


Hard Buttons
Five Hard Buttons provide quick access to often used control functions such as lights, music, audio/video source selection without the need to navigate through the graphical interface on your touchpanel.


2-Way
Convenient and reliable control with status feedback from controlled devices such as on/off or arm/disarm status, dimming value of lights, playlists, available stations.


RS-232
Two (2) control ports for 3-wire connection with the capability of polling status feedback from controlled devices or systems.


Relay
Four (4) built-in low voltage dry contacts that provide contact closure or switching control for loads up to 2A/30VDC (external power supply required).


Infrared
One (1) control port for 2-wire connection to infrared emitters, blasters and repeaters.


Sense Input
Six (6) inputs that sense contact closure from switches, windows or doors or voltage state from a voltage sensor to trigger a programmed control command or macro.


Ethernet
Standard 10/100 BaseT wired network connection for bidirectional control communication with RTI remotes, control accessories and devices that are controlled over IP network.


PoE
Power your touchpanel through a PoE network switch or PoE injector. No extra power supply required.


Zigbee
Standard wireless Zigbee connection for bidirectional control communication with RTI remotes.
