4K DigitalMedia 8G+®Transmitters
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.
This guide provides information about the following:

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.

Supplemental Guide – DOC. 7932A DM-TX-4K-202-C/DM-TX-4K-302-C: 4K DigitalMedia 8G+ Transmitters •7
HDBaseT Configuration
The DM-TX-4K-202-C and DM-TX-4K-302-C are HDBaseT certified, enabling direct
connection to other HDBaseT certified equipment. Via the DM 8G+ output of the
DM-TX-4K-202-C and DM-TX-4K-302-C, the transmitter can be connected directly to a
third-party HDBaseT compliant device without requiring a DigitalMedia receiver.
SIMPL Windows allows an HDBaseT receiver device to be added to the
DM-TX-4K-202-C or DM-TX-4K-302-C. The HDBaseT receiver device adds a COM port to
the DM-TX-4K-202-C or DM-TX-4K-302-C and enables two-way serial communication.
To add a third-party HDBaseT receiver device to the DM-TX-4K-202-C or
DM-TX-4K-302-C, use SIMPL Windows. An overview of the necessary step follows.
NOTE: For detailed information, refer to the SIMPL Windows help file.
In the Configure View of SIMPL Windows, add a third-party HDBaseT receiver device to
slot 9 for the HDBaseT receiver slot of the DM-TX-4K-202-C or DM-TX-4K-302-C.
HDBaseT Receiver Slot (Slot 9)
When the third-party HDBaseT receiver device is added to slot 9, the HDBaseT Receiver
symbol adds a COM port to the device and enables two-way serial communication.

USB HID Control Configuration
A keyboard, mouse, or other USB HID compliant device can be connected locally to the
USB HID port of the DM-TX-4K-202-C and DM-TX-4K-302-C. The USB HID compliant
device can be used to control a remote computer or other host device that is connected to
the USB HID compliant port of a DigitalMedia device, that is, a DigitalMedia transmitter or a
DMC input card of a DigitalMedia switcher.
Routing of the USB signals is handled by the DigitalMedia system. SIMPL Windows allows
routing of USB signals from the device connected to the USB HID port of the
DM-TX-4K-202-C or DM-TX-4K-302-C to the host device that is connected to the USB HID
compliant port of a DigitalMedia device. To configure USB routing, set the
<USB_HID_Control> serial input join to the IP address of the DigitalMedia device to which
USB signals are to be routed. The IP address must be in hexadecimal format. For detailed
information about the <USB_HID_Control> serial input join and about setting the IP
address, refer to the SIMPL Windows help file.
HDCP 2.2 Compliance
The DM-TX-4K-202-C and DM-TX-4K-302-C are compliant with HDCP 2.2. HDCP 2.2,
commonly referred to as HDCP 2, is the next generation of HDCP (High-Definition Content
Protection). Note the following about HDCP 2:
•Compared to HDCP 1, HDCP 2 brings a higher level of cryptographic protection to
HDMI technology.
•HDCP 2 is not HDMI 2. It is possible to have a system built on HDCP 1 and
HDMI 2, HDCP 2 and HDMI 1, or HDCP 2 and HDMI 2.
•Although not all 4K content requires HDCP 2, most 4K consumer video content
does require HDCP 2.
•Any product that supports HDCP 2 also supports HDCP 1.
•HDCP matters only when the source demands HDCP. If the source demands
HDCP 2, then every device in the signal path must support HDCP 2.
•There are no issues related to HDCP 2 and cabling—all cables are “compatible.”

DM-TX-4K-202-C and DM-TX-4K-302-C Troubleshooting (Continued)
TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION
The transmitter does not
remain powered on.
When the transmitter is not being
powered by the included power
pack, the DM OUT port is not
connected to a PoDM+, PoDM,
HDBaseT PoE+, or HDBaseT PoE
power sourcing equipment (PSE)
port that is required to power the
transmitter.
Ensure that the DM OUT port
is connected to an appropriate
PSE port when not being
powered by the included
power pack.
The SIMPL Windows program
is not operational.
In a configuration in which a
DigitalMedia switcher is not used,
the IP table is not set properly.
Verify that the IP table is set
properly in System Info in the
Crestron Toolbox application.
If the transmitter connects to a
DigitalMedia switcher, the
transmitter does not connect to
the correct DM input port of the
switcher.
Ensure that the transmitter
connects to the correct DM
input port of the switcher.
The video flickers or drops
when the transmitter is
touched or when metal in the
vicinity of the device is
touched.
The transmitter is not properly
grounded.
Ensure that the transmitter
is properly grounded.
NOTE: If, for any reason, the factory default settings of the DM-TX-4K-202-C or
