USB to Serial Adapter Hub manufacturers take you to understand the structure of the hub
USB to Serial Adapter Hub Manufacturers tell you that the external panel structure of a normal hub is very simple. USB to Serial Adapter Hub Manufacturers tell you that for example, D--Link's simplest hub is a cuboid, with AC power sockets and switches, an AUI interface and a BNC interface on the back, and a row of 17 RJ- 45 ports. There are also LED interface indicators and LED status indicators corresponding to each RJ-45 interface on the right side of the front.
USB to Serial Adapter Hub Manufacturers tell you that high-end hubs don't look much different from modern routers or switching routers. In particular, modern dual-speed adaptive Ethernet hubs generally have built-in switching modules that can realize mutual communication between internal 10Mb/s and 100Mb/s network segments, to realize the communication exchange between the nodes.
USB to Serial Adapter Hub Manufacturers tell you that such switching hubs are sometimes referred to simply as switches, which makes it difficult for first-time hub users to identify them correctly. However, it is a relatively simple method to identify the hub according to the backplane interface type.
The above is the USB to Serial Adapter Hub manufacturer's introduction and analysis of the structure of the hub, hope it helps you.
