Introduction
The Crestron®DM-TX-4K-202-C and DM-TX-4K-302-C are DigitalMedia 8G+®transmitters
and switchers that provide support for the transport of 4K and Ultra HD video signals.
The DM-TX-4K-202-C and DM-TX-4K-302-C provide two HDMI®inputs. In addition to the
HDMI inputs, the DM-TX-4K-302-C provides one VGA input and one analog audio input.
The DM-TX-4K-202-C and DM-TX-4K-302-C also function as control modules, providing
RS-232 and IR control ports. An Ethernet port and a USB HID port are also provided.

an HDBaseT device via CAT5e, Crestron DM-CBL-8G, or Crestron DM-CBL-ULTRA
cable;
Green LED indicates DM link status;
Solid amber LED indicates HDCP video;
Blinking amber LED indicates non-HDCP video
NOTE: Receiving PoDM+ or PoDM requires connection to a switcher or other
equipment that has a corresponding PoDM+ or PoDM PSE (Power Sourcing
Equipment) port. Receiving HDBaseT PoE+ or HDBaseT PoE requires connection to a
switcher or other equipment that has a corresponding HDBaseT PoE+ or HDBaseT
PoE PSE port. Any wiring that is connected to a PoDM+, PoDM, HDBaseT PoE+, 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.
NOTE: If the DM-TX-4K-302-C does not connect to the included power pack, the
DM-TX-4K-302-C requires PoDM+ or HDBaseT PoE+ to power a USB device
connected to the USB HID port. Standard PoDM or HDBaseT PoE can be used to
power the DM-TX-4K-302-C if no USB device connects to the USB HID port. Unlike for
the DM-TX-4K-302-C, standard PoDM or HDBaseT PoE can be used to power a USB
device connected to the USB HID port of the DM-TX-4K-202-C.

Configuration
This section provides information about the following:
•EDID configuration
•HDBaseT configuration
•USB HID control configuration
EDID Configuration
EDID (Extended Display Identification Data) configuration allows management of the EDID
that is to be sent to the upstream device connected to an HDMI input of the
DM-TX-4K-202-C or to an HDMI or VGA input of the DM-TX-4K-302-C. By default, the
EDID is set to DM default 4k 60Hz 2 ch for an HDMI input or to 01 DM default for a VGA
input.If a different EDID is desired, use DMTool to configure the EDID. An overview of the
steps necessary to configure the EDID is as follows:
NOTE: For detailed information, refer to the Crestron Toolbox™ help file.
1. Connect to the DM-TX-4K-202-C or DM-TX-4K-302-C.
2. Open the Setup window of the HDMI input for the DM-TX-4K-202-C or the Setup
window of the HDMI or VGA input for the DM-TX-4K-302-C.
3. In the EDID Configuration dialog box, configure the EDID by doing any of the
following:
oCustomize the current EDID.
oLoad an EDID template and modify it.
oCreate a new EDID file.
oLoad the existing EDID and modify it.
oObtain an EDID from the output and then save or customize it.
oApply an EDID that is saved on a computer.
