DigitalMedia 8G™ Fiber Transmitter 401
Setting the IP Address Selecting Inputs

For details, refer to the latest version of the DM-TX-401-S/S2
Operations and Installation Guide, Doc. 7257.
Setup of the IP address of the DM-TX-401-S/
DM-TX-401-S2 depends on the way the
transmitter is configured within the DigitalMedia
8G system:
● If the transmitter is connected to a receiver/
room controller, the transmitter uses its own
configuration settings. The transmitter ships
with DHCP enabled; however, the default IP
address can be assigned by holding down the
SETUP button while the unit boots up.
The default IP address of the DM-TX-401-S/
DM-TX-401-S2 is 192.168.1.238. The default
IP address overwrites the current setting.
● If the transmitter is connected to a DM
switcher, the transmitter is automatically
configured by the switcher.
If manual configuration of the IP address of the
transmitter is desired, use Crestron Toolbox™ to
set the IP address.
By default, automatic switching of inputs is enabled.
Automatic switching causes inputs to switch according to
the following priorities:
● Video switching priority: DisplayPort, HDMI, RGB,
composite
● Audio switching priority: DisplayPort, HDMI,
1/8” analog, dual RCA analog
The AUTO LED on the front panel of the transmitter 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
transmitter until the corresponding LED lights.
Pressing the SELECT button in succession cycles from
automatic switching (default selection) through the various
available selections in the following order:
● DisplayPort audio and video. The DISPLAY PORT
LED lights.
● HDMI audio and video. The HDMI LED lights.
● VGA video with 1/8” audio. The PC LED lights.
● Composite video with dual RCA audio. The VIDEO
LED lights.
● None. No input is selected.
After cycling through the above selections, pressing the
SELECT button returns to automatic switching.
