The ZB-2510 series are ZigBee-based repeater modules included in the ICP DAS product line. The main difference between these products is the transmission range. The ZB-2510 and ZB-2510-T support an extended transmission range of up to 100 meters, whereas the ZB-2510P and ZB-2510-PA can transmit to a maximum of 700 meters. All modules are able to operate in broadcast and user-defined route modes. When the repeater is set to broadcast mode, the transmission route is constructed by the ZigBee Host. The repeater will forward any data that it receives using broadcast mode. The advantage of this mode is that the repeater can be deployed in a “haphazard” manner without any concern about positioning. However, the main fl aw of this mode is that if there are too many broadcast data packets in a ZigBee network, it will cause the network to crash. In contrast, when the repeater is set to user-defined route mode, it will only forward data using the user configured route. The benefit of this mode is that the data loading of the ZigBee network will be reduced, but the user must plan the data transmission route for the entire ZigBee network before setting up the application. If a mistake is made on even one repeater point, the entire ZigBee network will be invalid.
