An optional 9-pin D-to-2.5 mm TRS configuration cable is available from
and can be used to connect your computer to this port. Figure 11 shows the configuration
and pin assignments of this cable.

Connecting over the Network
For increased signal distance or to connect to a 1:N application, you can connect one to
five gigabit network switches between the Ethernet ports of a transmitter and receiver.
•
Extron recommends that gigabit network switches be used with the USB Extender
Plus series in a network application. Although 10/100 network switches can be used,
they allow only low and full speed USB devices such as mouse and keyboards to
function correctly. No more than five network gigabit switches can be used between the
transmitter and receiver.
•
The USB Extender Plus series uses Layer-3 (TCP/IP) for pairing and Extron PCS, and
Layer-2 (UDP, MAC address) for communication and USB data transfer. Because of this
IGMP is not required or used.
•
Each network switch that is added between the transmitter and receiver adds latency or
degrades the signal, which may cause USB devices to function incorrectly. If a network
switch being used features Quality of Service (QoS), it can reduce the effect of network
congestion. However, it may not be effective in counteracting the latency that each
network switch adds.
•
The USB Extender Plus series is compatible with both managed and unmanaged
network switchers.
•
Multicast and Unicast do not apply to the USB Extender Plus series. This series features
its own proprietary technology when the 1:N feature is enabled.
•
Traffic and communication to one receiver is not broadcast by the transmitter to all
receivers. Each packet from a transmitter is designated to a single receiver with specific
MAC address.
•
The USB Extender Plus series is compatible with both IPV4 and IPV6.
•
USB Extender Plus models used in a network application and the PC running the PCS
software must all be on the same subnet and network.
•
USB Extender Plus models that are used in a network application should be on their
own independent network to keep latency low. If the latency gets too high then packets
are lost or take too long and the USB protocol falls apart.
