HUB is the life of NDI. Instructions on how to choose HUB!

Difference between unmanaged switch and fully managed switch

There are two types of HUB, "unmanaged switch" and "fully managed switch". To put it simply, it is unmanaged that branches at the cable core level like the octopus wiring inside the HUB, and it is fully managed that each port is equipped with a dedicated CPU that manages the flow rate. I want you to.

Actually, even if it is written as "1G HUB", 1G cannot be used for the number of outlets, and there are products with the ability to process only 1G for the entire HUB. HUBs for office use and HUBs for video and audio have different requirements.

With an inexpensive HUB, the performance of NDI is not exhibited, and phenomena such as dropped frames and devices not being recognized occur, and it is disappointing to see that it is evaluated as "NDI cannot be used". ..

From here, let's introduce the functions of the HUB using NETGEAR's "M4250-26G4XF-PoE +" as an example. The screen below is an example of a NETGEAR fully managed switch management screen. This product is designed to be web-based and easy to manage and configure.

For example, you can easily set a VLAN (Virtual Run: a technology to create a virtual LAN segment) just by creating a profile on the screen you see. It is also possible to set the DHCP server individually for each VLAN if necessary.

On September 17, 2021, NETGEAR released the latest update "Version 13.0.2.24" of the M4250 series to support "NDI 5".

In the conventional HUB, when voice transmission such as DANTE and NDI are used together, a problem may occur. In the new version, you can create a VLAN for each HUB connection port and realize only NDI in one unit. This is a nice feature.
