Switcher Based Systems
DM room boxes (both CAT and Fiber versions) come fully equipped with an integrated Ethernet switch, and a “spare” port is
provided. In a scenario when the room box is connected to a DM switcher, this port can be used for connecting other Ethernet
devices. In a point-to-point scenario, the Ethernet port can be used as an uplink to the main network. For example, if a
system contains a DM-TX-200 and a DM-RMC-100, the room box must serve as the uplink point since the DM-TX-200 does
not provide an Ethernet port. But if the DM-TX-200 is replaced with a DM-TX-100 or DM-TX-300, then Ethernet uplink can
happen at either of the transmitters
or at the room box since all of these devices have an available Ethernet port. So in
addition to HDMI, control, and USB HID transport, DM also provides a method to transport Ethernet.
