The NTI XTENDEX ST-IPUSBH-1G HDMI USB KVM Over IP Extender with Audio, RS232, and IR provides remote KVM (USB keyboard, USB mouse, and HDMI monitor) access to a USB computer or HDMI source up to 330 feet over a Gigabit network using a single CAT5e/6 cable. Each ST-IPUSBH-1G consists of a local unit that connects to a computer or HDMI source, and a remote unit that connects to a monitor, mouse, keyboard, speaker, microphone, and other USB devices.

The local and remote ST-IPUSBH-1G units can be connected together for a Point-to-Point connection via CAT5e/6 cable or a Point-to-Many connection via a managed network switch.

Question: (Point-to-Many connection via a managed network ).Do you mean that I have to Create VLAN for ST-IPUSBH-1G & ST-IPUSBH-L-1G.step? Thank you.
Answer: Thank you for your inquiry,

In a multi-point configuration, that is correct - you would manage the extenders units over VLAN. With point-to-point you could use VLAN or just plug the CATx wire directly into the receiver.
