Two-port Gigabit RJ45 switch module

The Kisdoo NW021 is a passive A/B selector that routes a single RJ45 link to one of two connected devices. It handles 100M and 1000M Ethernet as well as eight-wire telephone circuits without any external power or driver installation.

Desktop users needing manual port switching

This module suits anyone who wants to share one network drop or phone line between two endpoints by flipping a physical switch. It will not serve buyers who require both ports active simultaneously or who need automatic switching between connected devices.

Fits a desktop cable run with no power socket

The metal enclosure connects inline between the wall jack and the two target devices using standard RJ45 patch leads. Because it draws no power, it adds no load to a UPS or power strip and leaves the surrounding outlet free for other equipment.

Questions about this item

What Ethernet cables do I need to connect the two RJ45 ports on this NW021 selector?

Use standard RJ45 patch cables rated for at least 1000 megabits per second to match the gigabit capability of each port.

Can I keep my 100 megabit per second router connected to one side while using the other port at gigabit speed?

Yes, the selector passes the signal through without conversion, so each link runs at the highest speed both ends support.

How can I confirm the NW021 is switching traffic correctly after I press the A/B button?

The active port LED lights up and the connected device immediately shows a live link with full duplex at the negotiated speed.
