GENERAL DESCRIPTION

XICATO GALAXI CARD

XGC (Xicato GalaXi Card) is a small printed circuit board assembly (PCBA) that enables third party manufacturers to develop control devices that can participate as wireless nodes in a Xicato Controls Bluetooth® mesh network. Each XGC is factory programmed with a universal firmware image that can be customized by a device manufacturer (OEM) using Xicato XGC Configuration Tool software.

XGC employs a physical form factor that facilitates future evolution as technology advances. XGC-LCI-U3 will be over-the-air, field updatable to the future Xicato Bluetooth SIG standard mesh implementation

PWM CONTROL

XGC can both be configured to support one of four PWM operating modes:

(1) single-channel PWM output with separate on/off control (“1ch dimmer”)

(2) 2-channel PWM output with individual channel and master dimming control (type M2D), or

(3) 4-channel PWM output with individual channel and master dimming control (type M4D), or

(4) up to four ganged PWM channels controlled together by a single command (G4)

The PWM frequency is programmable by the OEM to meet the constraints of device hardware, and is applied uniformly but out-of-phase on each channel.1

PWM signals vary in duty cycle based on a commanded intensity value between 0% and 100%. The PWM output can be interpreted through external circuitry (i.e. by the OEM device) any way desired, and can be controlled by Xicato Control Panel software and/or by third party software that talks to the device either directly over Bluetooth or through the HTTP API of the Xicato Intelligent Gateway (XIG). For example:

• As a single channel driver dimming signal, either a direct command to a driver, or one that is translated into a 0-10V analog or DALI command. XGC has been implemented this way in devices from multiple vendors.

• Two or Four independent channel controls – set the master channel to 100% and then don’t use it for any further control input. XGC is being used today in this application.

• As a two- or four-channel color mixer (M2D, M4D): two or four independent channels controlling CCT or color point with a master controller for intensity that maintains the relative intensities of the individual channels

• Tunable white control – the scene control can be used to independently move two channels (or even two independent devices) in opposite directions to achieve the desired color temperature. If using XGC in M2D or M4D mode, the master channel can be used to adjust the intensity up/down. However, one note must be made about the master channel control: the intensity range on each channel is 0.1% to 100%. It will not increase the group intensity beyond the point that any individual channel is at 100%, nor decrease intensity below the point that any channel is at 0.1%. Once any channel hits 0.1%, no further dimming will occur except to turn all channels off. This is done to prevent the color shift that will occur if individual channels are turned off one by one as the entire group is dimmed.

• As beam angle control command, as for the LensVector product. The PWM signal can be translated by a third-party device into the native control structure for LV to widen or narrow the optical aperture, e.g. from 0% (no beam focus modification) to 100% (maximum beam focus modification). Or, two channels can be allocated to CCT control and two to LV control for x/y aperture control.

• As a shade control command, telling a shade controller to lower the shade to some percentage between wide open and all the way closed.

• As a temperature control command, telling e.g. a thermostat to go to some percentage of the distance between set minimum and maximum temperature settings.

1 Note that duty cycle switch-off instants depend on the duty cycle commanded by software, and may occur simultaneously on multiple channels on a periodic basis as a sub-harmonic of duty cycle.


• As an audio sound level command… • Etc.! Xicato does not constrain in any way the way that the PWM duty cycle is interpreted in the end device.

Note that it is the responsibility of the external circuitry to deliver the desired end result (dimming level, color, lens aperture, shade level, etc.) from the XGC input. Xicato’s responsibility is to provide the requested PWM duty cycle(s) in response to Bluetooth control commands.

UART BASED CONTROL

XGC can also be programmed by the OEM to communicate bi-directionally with the device with a serial protocol over UART (Universal Asynchronous Receiver/Transmitter). The downstream channel is a DMX512-like protocol, and the return channel complies with standard Remote Device Management (RDM). While requiring more intelligence in the device, UART provides much greater flexibility to control more channels and different types of devices, while the RDM return channel allows the device to provide configuration and status information through the XGC for communication over the Bluetooth network to control and administration applications. For example, the XGC can:

• Control the CCT and intensity

• Control intensity, CCT, hue (color) and saturation (chroma) of a color tunable module

• Control both light intensity and beam angle in a module that incorporates the LensVector LCD lens

• Control a pan-tilt mechanism

• Control a window shade

The UART protocol definition is available from Xicato to customers of the XGC-LCI-U3.

XGC CONFIGURATION TOOL SOFTWARE

The XGC Configuration Tool carries a software license that automatically programs a unique OEM code into the device. This code can be read by application and management software such as the Xicato Control Panel to uniquely identify the device manufacturer in the user interface. In addition, OEMs can configure device model numbers, serial numbers, and additional information into the device for recall by application software. The XGC Configuration Tool allows OEMs to export the mapping between their 2-byte integer model codes and their external model numbers and send the export file to Xicato for proper interpretation by application software.

CUSTOMIZATION Xicato welcomes conversations with device OEMs that would like additional feature functionality, including alternative interfaces or other capabilities. Send an email to [email protected] to begin the discussion.


XGC FEATURES

FUTURE PROOF FORM FACTOR

Customers that adopt the XGC can rest assured that the product they build today will accommodate future evolutions of the XGC. Individual components and/or placement may change over time, but the overall dimensions as well as the component placement and BLE antenna keep-out area should remain unchanged.

BLUETOOTH MESH NETWORKING

XGC supports the Xicato Bluetooth mesh protocol today, and will be capable of supporting Xicato’s implementation of the new Bluetooth SIG mesh standard. With excellent radio transmission power and receive sensitivity, it provides an outstanding link budget for reliable point-to-point and mesh communication.

PROGRAMMABLE PERSONALITY – SIMPLIFIED INVENTORY FOR MANY DEVICE TYPES

Each XGC supports multiple programmable personalities, model numbers, serial numbers, and more, minimizing OEM inventory.

TEMPERATURE SENSING

Temperature sensing is built into the Bluetooth module on the XGC, to enable monitoring of the conditions under which the PCB is operating. The XGC reports temperature over Bluetooth for monitoring by local or remote devices.

CONFIGURABLE ADVERTISING POWER AND INTERVAL

Depending on your application, XGC devices can be configured with different transmit power settings and intervals to increase data granularity, or to conserve power and bandwidth. All configuration of the XGC can be performed using the Xicato Control Panel software, the Xicato Intelligent Gateway (XIG), or compatible software from third party vendors.

ONBOARD OR REMOTE CONFIGURATION RESET

XGC has an onboard push-button switch that will reset the card to an unprovisioned state. A remote, normally open switch can also be wired to a pair of solder pads on the card.

PROGRAMMABLE TYPES (DEVICE PERSONALITIES) PWM-based control models:

1. 1-channel dimming with on/off: a single channel PWM output, configurable from 100 Hz to 60 kHz, and a single on/off output that can be used to turn external circuitry on/off or indicate that the PWM output is active.

2. M2D: 2 independent PWM output channels, with proportional Master control of both channels. The frequency is the same for all channels, but the duty cycle for each channel can be controlled independently.

3. M4D: 4 independent PWM output channels, with proportional Master control of all four channels. The frequency is the same for all channels, but the duty cycle for each channel can be controlled independently.

4. G4: 4 channels that are all controlled together using a single slider

UART based control models:

1. CCT control: XGC can command either a percentage value between two defined CCT points, or can command a specific CCT value in 1-Kelvin increments

2. CCT + Hue + Saturation control: XGC can request a CCT value, a 360˚ hue vector, and a 0-100% saturation value 3. Beam Angle control (e.g. LensVector) – XGC can request a percentage value between two defined endpoints 4. Pan and Tilt control 5. Shade control
