NOTE: The DM OUT port is a PoDM (Power of DM) or HDBaseT® PoE
(Power over Ethernet) PD (Powered Device) port. To receive PoDM or
HDBaseT PoE, the DM-TX-401-C requires a connection to a DM®
switcher or other equipment that has a PoDM or HDBaseT PoE PSE
(Power Sourcing Equipment) port. Any wiring connected to a PoDM or
HDBaseT PoE PSE port is for intrabuilding use only and should not be
connected to a line that runs outside of the building in which the PSE is
located.

Determine the IP Address
The configuration of the DM-TX-401-C within a DM 8G+® system
determines how the IP address of the DM-TX-401-C is set:
lIf the DM-TX-401-C is connected to a DM switcher, the IP address is
configured by the switcher automatically.
lIf the DM-TX-401-C is connected directly to a DM 8G+ receiver
(commonly referred to as a standalone configuration in which no
DigitalMedia switcher is used), the IP address of the transmitter is
assigned using DHCP (Dynamic Host Configuration Protocol) by
default. If you wish to assign a static IP address, do either of the
following:
oTo assign the default static IPaddress of the transmitter, hold
down the SETUP button while the unit boots up. The default static
IPaddress 192.168.1.234 overwrites the current setting.
oTo manually set a static IP address other than the default address,
use the Crestron Toolbox™ application.
Select an Input
By default, automatic switching of inputs is enabled. Automatic switching
causes inputs to switch according to the following priorities:
lVideo switching priority: DisplayPort™, HDMI, RGB, composite
lAudio switching priority: DisplayPort, HDMI, 1/8 in. analog, dual RCA
analog
The AUTO LED on the front panel of the DM-TX-401-C lights to indicate
that automatic switching is enabled.
To manually select the desired audio/video input, press the SELECT
button on the front panel of the DM-TX-401-C until the corresponding
LED lights.
Input Selection LEDs and Button
Pressing the SELECT button in succession changes the input selection
from automatic switching (the default setting) to the various available
selections in the following order:
lDisplayPort audio and video: The DISPLAY PORT LED lights.
lHDMI audio and video: The HDMI LED lights.
lVGA video with 1/8 in. audio: The PC LED lights.
lComposite video with dual RCA audio: The VIDEO LED lights.
lNone: No input is selected.
After cycling through the selections above, pressing the SELECT button
returns the DM-TX-401-C to automatic switching.
