Mounting

The DM-TX-100/100-F has attached mounting brackets and is
designed to be mounted on a flat surface or attached to a rack rail in
the back of an equipment cabinet. It may also be used portably for

connection to a wall plate input, and is compact enough to fit discreetly
inside a presentation lectern or beneath a table.

The DM-TX-200, supplied with a mounting bracket and attaching
screws, is designed to be mounted on a flat surface and can even be
concealed inside a raceway.

The DM-TX-300N/300N-F is designed to be mounted in an equipment
rack using supplied “ears.” These ears must be installed prior to
mounting the unit. The only tool required is a #2 Phillips screwdriver.

WARNING: To prevent bodily injury when mounting or servicing this
unit in a rack, take special precautions to ensure that the system

!

remains stable. The following guidelines are provided to ensure your
safety:

• When mounting this unit in a partially filled rack, load the rack
from the bottom to the top with the heaviest component at the
bottom of the rack.

• If the rack is provided with stabilizing devices, install the
stabilizers before mounting or servicing the unit in the rack.

NOTE: If rack mounting is not required, rubber feet are provided for
tabletop mounting or stacking. Apply the feet near the corner edges on
the underside of the unit.

NOTE: Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g., use of power
strips).

DigitalMedia™ Transmitters

Connecting to DigitalMedia Room Controller or DigitalMedia Switcher

3

Using a DigitalMedia™ cable (DM-CBL-P or DM-CBL-NP), connect the
transmitter(s) directly to a DigitalMedia Room Controller (if required, first connect
to a DigitalMedia Repeater and then connect the output of the repeater to a room
controller), or connect the transmitter(s) to a DigitalMedia Switcher (via a
DMC-CAT/DMC-F interface card).

NOTE: DigitalMedia cable should have a minimum length of 15 feet (4.6 meters).

1. Configurations with a transmitter connected to a room controller require a

power supply, PW-2407RU, connected either to the transmitter or to the room
controller. For configurations using DM CAT cables, the power supply must be
purchased; for configurations using fiber cable, the power supply is provided.

quickstart guide

2. Configurations with a DigitalMedia Switcher may not require an additional

power supply; the switcher typically supplies power for the transmitter. Use the
Crestron Power Calculator to verify that there is enough DMNet power on the
switcher.

3. For detailed instructions on the DigitalMedia Room Controller (DM-RMC-100

and DM-RMC-100-F) or the DigitalMedia Switcher, refer to the latest version
of their respective guides (Doc. 6743, 6744, and 6755) which can be obtained
from the Crestron website (www.crestron.com/manuals).

Connecting AV Sources, Outputs, and Verifying Signals

4

Check that the DM input of the room controller or DigitalMedia Switcher are
connected to the transmitters, and connect/turn on power. Check the transmitter
LEDs, the output display, and verify the signal settings.

• Check the room controller PWR LED ( on/green).

• Check the DM LINK LED ( on/green).

• Check that the VIDEO LED is on/green when a video signal is detected.

The DM-TX-100/100-F does not have video switching because there is only one

AV input.

The DM-TX-200 has auto routing functionality by default:

• If no signal is present on HDMI IN, RGB IN and AUDIO IN will be

routed.

• If a signal is present on HDMI IN and no audio is embedded in the
video, (i.e., a DVI signal) HDMI IN video and AUDIO IN audio will be
routed.

• If a signal is present on HDMI IN with audio embedded in the signal,
HDMI IN audio and video will be routed.

The 300N/300N-F have front panel controls for making selections.

Setup of the IP address for the DigitalMedia transmitters depends on
the way the transmitters are configured within the DigitalMedia system.

1. Transmitters connected to a room controller use their own configu­ration settings. The units ship in DHCP mode, but the following
static addresses can be set on the units by holding the SETUP
button depressed while the unit boots up:

• The DM-TX-100, 200, and 300 series units default to

192.168.1.231/232/233.

• The DM-RMC-100/100-F defaults to 192.168.1.241/242.

NOTE: This process overwrites any current settings. Also, for the
DM-TX-100/100-F, the USB console is enabled and HID functionality
is blocked until reboot.
