ZigBee Design 2017-2-20 HC-800 and HC-250 ZigBee Improvements ? What ZigBee improvements have been made with the new controllers? ?M ore powerful ZigBee processor – FASTER ? Control150 devices per ZAP if using HC-800 or HC-250 ? ZigBee amplifier to provide better ZigBee coverage. ? The HC ‐ 800 has an optional 3 meter external ZigBee antenna kit. ? The 3 meter ZigBee antenna will allow you to more effectively use the HC-800 in a rack configuration. 2017-2-20 HC-800 Should Run all these Services ? Zserver – A software process that doesn ’ t require an active radio antenna on the controller it is running on. (HC-800 if it ’ s in project or HC-250 if single room project) ? ZAP Coordinator (Also is a ZigBee Access Point) – Responsible for establishing and managing the work. Must be an HC class controller with a radio. (Use HC-800 or HC-250) – CENTRALIZE THE ZAP COORDINATOR ? ZigBee Access Point (ZAP) – Talks to all ZigBee Devices municates back to the ZigBee Server via E . – Only use extra ZAP ’ s if needed. – All controllers can be ZAP ’ s but HC-800 and HC-250 are best. ZigBee System Design Considerations ? Run only the number of ZAPs needed. ? Dense node ~ 150 devices / ZAP if using HC-800 or HC-250 ? 70 devices / ZAP if using other controllers ? work should utilize more based on layout Centralize ZAP Coordinator Director ZigBee Server ZAP Coordinator/ZAP 2017-2-20 Multiple ZigBee Access Points (ZAP ’ s) ZAP ZAP Director ZigBee Server ZAP Coordinator ZAP ’ s need to be within “ hopping ” Radio Range of the ZAP Coordinator when the mesh first comes on line. (Every time the es up) 2017-2-20 Multiple ZigBee Servers Director ZigBee Server ZAP Coordinator/ZAP ZigBee Server ZAP Coordinator/ZAP ZigBee Servers Only Require Multiple ZigBee Servers Benefit –S upport for ZigBee devices that are not able to be joined into a single mesh. – Can be used to force devices to parent to a specific ZAP Disadvantages –
