During the installation or use of the wireless module, the module and the module are often not on the same network segment, which causes normal communication between the wireless module devices. How to set the wireless module on the same network segment? First, we You must first understand the three major components of the network segment, NET ID, NODE ID and channel.
NetID is a unique identifier for digitally encoding an entity and applying it to the network. Just like each of our ID numbers, it represents our unique digital ID, so NET ID is called the network ID or network ID number. If the NET ID of the wireless module on the same network segment is inconsistent, communication cannot be achieved.
NODEID is the node number, node ID, node identifier, and simply a connection point, which is generally used to send, receive, or forward information. In the same network, the NODE ID of each wireless module should be set differently, otherwise communication cannot be realized.
The channel refers to the channel for communication between the wireless modules, and is the medium for signal transmission. To maintain stable communication between the wireless modules, it needs to be set on the same channel.
By knowing the three parts of the network segment, we can know that when the wireless module is not on the same network segment, we need to set the NET ID (network ID) and channel of the wireless module to be the same, NODE ID (network node) ) Set it to be different, you can set the wireless module on the same network segment.
