DM-TX-300N-F in a Typical Application
No LAN connection is required for these devices to transmit HDMI in a point-to-
point configuration. If you wish to use the control ports (IR, RS-232, Relay, Sense)
from a control system, you can connect either LAN port (the one on the
DM-TX-300N/-F or the DM-RMC-100/-F) to the control system’s network. Both
devices will be connected because Ethernet is embedded inside DM. You may also
use the other LAN connection to provide Ethernet connectivity to a remote device.
