product explain
1. Manual single point meter reading Yl-801ug supports single point meter reading, and can read data from each form independently without networking. An yl-800t module (version 2.7 or above) is integrated into the handheld, and the module is set as the central module, and the parameters are consistent with the table parameters. Send data according to the protocol to read and control the meter.
2. Remote meter reading of concentrator The concentrator can use 3G / 4G and small wireless low-power MAC network for remote meter reading. Before the first meter reading, it is better to let the concentrator to network. The networking takes time, and the networking is completed. After the routing table is established, the remote server can get the number of nodes and network path, and can also read the meter wirelessly There are a small number of meters without network path, which can also be read, but it will be forced to find the path.
3. Meter reading by concentrator and handheld computer Yl-801ug protocol supports single point and network commands, so mixed meter reading can also be realized, so it is convenient to read meter by hand when there is no network.
