3.5 Colour In-wall System Controller with Built-In Processor
larger imageClick the image to enlarge

With the release of RTI Integration Designer Apex 10.1 and Integration Designer 9.11, now the KX3 in-wall touchpanel can also serve as a control processor. It can also act as an expansion processor for systems using an XP series control processor, or even another KX3. The incredibly flexible touchpanel also includes a built-in ZigBee transceiver, making for an all-in-one solution for a single or multiple room system. Once the control processor feature has been activated in the software, the KX3 can route IR, deliver 2-way serial control, and can run any driver written for the XP processor platform.

Powered by POE, local power supply, or CB8 connecting block, the keypad has a 3.5” WVGA (480x800) screen with five engravable hard buttons to maximize real estate on the screen. It also has integrated 10/100 Base-T and 802.11g wireless Ethernet for viewing video from network cameras, and powerful 2-way feedback. A built-in camera, microphone and speaker allow for video intercom sessions, and stylish faceplates can be added in white, black or brushed aluminum to match any décor.

As a processor, or used in conjunction with a processor, direct control of devices can be achieved via IR, IP, RS- 232, sense ports, relays and built in astronomical clock for time-based event control. Due to its hybrid design, the KX3 offers excellent value and a powerful control option in commercial and residential settings.

Commercial Applications

Since the KX3 is a touchpanel and processor in one, the powerful unit is perfect in a classroom, lecture hall, huddle space, conference room or just about any setting where intuitive and cost-effective control is required. Since the KX3 can run two-way drivers via IP and RS-232 without any need for additional equipment, it can serve as an all-in-one interface and processor for control over the AV, climate, scene-based lighting and shades, security, and more. If additional control is required, expansion devices like the PCM-4 or ESC-2 can be easily implemented. If the project calls for additional user interfaces, the KX3 built-in ZigBee and Ethernet options allow the addition of a hand-held remote, countertop or in-wall touchpanels and even a mobile device running the RTiPanel app. These features make it an ideal candidate for an all-in-one solution in just about any commercial environment.

Residential Applications

While the KX3 can serve as the processor to facilitate media streaming, surveillance, lighting and more, the unit is ideally used as an expansion device to an XP processor in a residence. If installed in a remote location in the home, ZigBee based controllers can be utilized and communicate with the main XP control processor over the network. This makes it easy to provide a control solution in residences where creating a large ZigBee network is challenging. If there is local equipment, a KX3 can control devices directly or communicate with other expansion devices, such as the PCM-4, ESC-2, RCM-4, and other KX3 keypads in the residence.

Doing Triple Duty

In large projects that require many intensive two-way IP drivers that may bog down an XP processor, a KX3 can even be used as an expansion device in processor mode to handle some of the burden. In this situation, drivers can be set to run on the KX3 instead of the XP processor. This solution is recommended for dealers who are utilizing many resource-hogging drivers and are finding issues with latency and low memory.
