ZT-2530M is a ZigBee Bridge used to connect two different ZigBee networks. The absorption of wireless signals by buildings and other obstacles in the urban environments significantly impair wireless transmission. Therefore, ICP DAS provides the new ZT-2530M - the ZigBee bridge, which is equipped with dual antennas and combined a ZigBee coordinator with a ZigBee router. It can be full hardware configuration, and be used to bridge the communication between indoor and outdoor units or divide complex network to enhance efficiency. The ICP DAS ZigBee products are designed primarily to help users to build a wireless communication system in an environment where it is hard to physically wire up the devices. They are widely used in industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation, home automation and so on.
