11 / 37 page ACTIVE NTWK SEARCH State This state is a condition where the demo board is actively searching for a network but has not joined a network. This operation for actively searching for a network will remain for approximately up to two minutes. If no network is found by that time limit, the demo board will enter into the OFF NETWORK state. If a network is found it will enter the NETWORK JOIN state. Power-cycling while in this state will reset the timer and keep the demo board in this state for two additional minutes. If a network is found it will leave this state and enter the NETWORK JOIN state. The white/tri-color LEDs on the board will operate like a conventional non-connected light while in this state. NETWORK JOIN State After a demo board leaves the ACTIVE NTWK SEARCH state and enters this state, the white/tri-color LEDs will flash 10 times to indi- cate successfully finding and joining a network. This state is transitory as the light moves immediately to the ON NETWORK state once the LEDS complete their flash sequence. Power-cycling at this time will only impair the 10 LED flashes, but not prevent entry into the ON NETWORK STATE once the power is reapplied. ON-NETWORK State This state is a condition where the demo board is connected to a ZigBee HA 1.2 network and is not searching for a network. While in this state, the white/tri-color LEDs illumination on the demo board will correspond to commands the demo boards receive from the Zig- Bee network. This state contains multiple entry and exit paths depending on various factors such as number power-cycles received within a short time period of a few consecutive seconds. If the power to the demo board is removed for long periods of time, the demo board will immediately rejoin its original joined network when power becomes available and will not seek other networks, unless the user forces it to leave its joined network as will be descri- bed within this section. If the demo board is power-cycled four times, the demo board will temporarily enter the IDENTIFY state while remaining on its joined network. If the demo board is power-cycled from five to nine times, the demo board will temporarily enter the NETWORK STATUS state while remaining on its joined network. If the demo board is power-cycled ten times OR if the demo board receives a leave network command, the demo board will enter the LEAVE NETWORK state. IDENTIFY State The purpose of this state is to help an installer (or user) identify which bulb is being communicated to by visually flashing in a specified pattern so this person can locate the targeted light. After a demo board leaves the ON-NETWORK state and enters this state, the white/ tri-color LEDs will flash at a 0.5 Hz rate. This state is temporary and will return the demo board into the ON NETWORK state once the state's timer reaches its time limit or if power is cycled at least once to the demo board. There are two ways to enter this mode depend- ing on the intended application. The first method is done locally to the bulb by power cycling it 4 times. The main purpose of this method is to support EZ Mode commis- sioning, whereby the light becomes discoverable by other devices as a candidate for pairing. The bulb will blink at 0.5 Hz until the Iden- tify Mode times out after 3 minutes. The second method is done remotely by sending an Identify command from a gateway. The main purpose of this method is to allow an installer to visually locate the bulb in question. The bulb will blink at 0.5 Hz until the Identify Mode for the duration is requested by the gateway. NETWORK STATUS State The purpose of this state is to help an installer (or user) identify if the light is successfully connected to a network. After a demo board leaves the ON-NETWORK state and enters this state, the white/tri-color LEDS will flash at a 2 Hz rate. This state is temporary and will return the demo board into the ON NETWORK state once the state's timer reaches its time limit or if power is cycled at least once to the demo board. LEAVE NETWORK State After a demo board leaves the ON NETWORK state and enters this state, the demo board will leave the joined network and will indicate this process is in action by slow flashing the white/tri-color LEDS three times at a 0.5 Hz rate. This state is termporary and will place the demo board into the ACTIVE NTWK SEARCH sstate once the LEDs complete their flash sequence. Power-cycling will only impair the slow LED flashes but not prevent entry into the ACTIVE NTWK SEARCH state once the power is reapplied.
