video distribution device via Cat5 cabling.
FIG. 18 LAN ports
Important: You must have access to a DHCP server to initially configure the encoder.
WARNING! It is possible to disable LAN ports 2-4 and leave only port 1 enabled. Since it is possible to turn off these
ports, you should ALWAYS connect your main network artery to port 1.
Note: The Ethernet switch in the encoder is intended to be used as a workgroup extender switch for conveniently
connecting devices such as PCs, touch panels, and other network-connected A/V equipment. It is not a smart switch, and
as such other encoders or streaming devices should not be connected to the switch ports on the encoder. If multiple
encoders are to be used in a location they should each have a dedicated facility network connection or a smart switch
should be added that can have multiple encoders connected to it.
