Abocom GS400 is a 4-port gigabit switch that provides high-speed network connectivity for your devices. It supports 10/100/1000Mbps speeds, and its auto-negotiation feature ensures that it will automatically adjust to the highest speed supported by your devices. The GS400 also supports full-duplex operation, which allows for simultaneous data transmission and reception.

With its four ports, the GS400 can be used to connect multiple devices to your network, such as computers, printers, and storage devices. It also supports VLANs (virtual LANs), which allow you to segment your network into multiple logical networks. This can be useful for separating different types of traffic, such as business and personal traffic, or for isolating devices that should not be able to communicate with each other.
