The registry is defined as a string of code that is sent to the software when a TCP
connection is established between the computer software and the serial server
module (hereinafter referred to as the module) so that the software knows which
module is communicating with it. This string of codes is the registry.
The registration package is very suitable for the monitoring of the Internet of things,
because the cloud software generally runs on the public network server of the
Internet, while the modules are scattered in various collection and monitoring
points. How to make the cloud software identification module is very important and
necessary for the realization of Internet of things communication.
Shanghai ZLAN serial server to provide the following types of registration.
8.1.1 Connect to send MAC Addresses
Connect to send MAC addresses: this is not only for model 4 (like 5143),
but also for regular models. It does this by sending its MAC address to the
cloud when the module is connected to the cloud. Since the MAC address
is unique, the device can be uniquely identified. This approach is simple
and effective without having to write a registry for each device. To use it,
click "more advanced options" in the device Settings dialog box, find "send
MAC address when TCP is established" in the middle and upper part,
check the box in the front, then go back to the Settings interface and click
"modify Settings".
