Configuration
This section provides information about the following:
lEDID configuration
lHDBaseT configuration
lUSB 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 DisplayPort input of the DM-TX-4K-302-C. By default, the
EDID is set to 4K60 444 2CH Non-HDR for HDMI and DisplayPort inputs. 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™ software help file.
1. Connect to the DM-TX-4KZ-202-C or DM-TX-4KZ-302-C.
2. Open the Setup window of the HDMI input for the DM-TX-4KZ-202-C or the Setup
window of the HDMI or DisplayPort input for the DM-TX-4KZ-302-C.
3. In the EDID Configuration dialog box, configure the EDID by doing any of the
following:
lCustomize the current EDID.
lLoad an EDID template and modify it.
lCreate a new EDID file.
lLoad the existing EDID and modify it.
lObtain an EDID from the output and then save or customize it.
lApply an EDID that is saved on a computer.

EDID Configuration Dialog Box for HDMI Input (DM-TX-4K-302-C Dialog Box Shown)
HDBaseT Configuration
The DM-TX-4KZ-202-C or DM-TX-4KZ-302-C are HDBaseT certified, enabling direct
connection to other HDBaseT certified equipment. Via the DM 8G+ output of the
DM-TX-4KZ-202-C or DM-TX-4KZ-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-4KZ-202-C
or DM-TX-4KZ-302-C. The HDBaseT receiver device adds a COM port to the
DM-TX-4KZ-202-C or DM-TX-4KZ-302-C and enables two-way serial communication.
To add a third-party HDBaseT receiver device to the DM-TX-4KZ-202-C or
DM-TX-4KZ-302-C, use SIMPL Windows. 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-4KZ-202-C or DM-TX-4KZ-302-C.
NOTE: For detailed information, refer to the SIMPL Windows help file.

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.
Addition of HDBaseT Receiver to Slot 9 and COM Port in Slot 1
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-4KZ-202-C and DM-TX-4KZ-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.
USB signal routing is handled by the DigitalMedia system. SIMPL Windows allows USB
signal routing from the device connected to the USB HID port of the DM-TX-4KZ-202-C or
DM-TX-4KZ-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-4KZ-202-C and DM-TX-4KZ-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:
lCompared to HDCP 1, HDCP 2 brings a higher level of cryptographic protection to
HDMI technology.
lHDCP 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.
lAlthough not all 4K content requires HDCP 2, most 4K consumer video content
requires HDCP 2.
lAny product that supports HDCP 2 also supports HDCP 1.
lHDCP is needed only when the source demands HDCP. If the source demands HDCP
2, then every device in the signal path must support HDCP 2.
lThere are no issues related to HDCP 2 and cabling—all cables are compatible with
HDCP 2.

Troubleshooting
The following table provides troubleshooting information. If further assistance is required,
contact a Crestron customer service representative.
DM-TX-4KZ-202-C or DM-TX-4KZ-302-C Troubleshooting
Problem Possible Cause(s) Corrective Action
Video is not
displayed, but the
audio may be
heard.
The HDCP settings of one or more
DigitalMedia devices in the signal path
do not support the HDCP level of the
source.
Ensure that the HDCP settings
of all DigitalMedia devices in
the signal path support the
HDCP level of the source.
The display does not support the HDCP
level of the source.
Ensure that the display
supports the HDCP level of the
source.
Video is not
displayed.
The desired input may not be selected in
DMTool.
Ensure that Auto mode is
selected or that the desired
input is selected in DMTool.
The HDMI video is
intermittent.
The HDMI cable connections are faulty. Verify that each end of the
cable is connected properly.
The LAN
connection is
unresponsive.
The transmitter and another
DigitalMedia endpoint are both
connected to a DigitalMedia switcher.
The LAN port of the other endpoint is
also connected to an Ethernet switch.
When a DigitalMedia endpoint
is connected to a DigitalMedia
switcher, the LAN port of the
endpoint cannot be connected
to an Ethernet switch.
Disconnect the LAN port from
the Ethernet switch.
The transmitter
cannot establish a
link to the device
that is connected
to the DM OUT
port. The DM link
status LED is off.
The cable connections are faulty. Verify that each end of the
cable is properly connected. If
necessary, check the cable
terminations.
The transmitter
does not remain
powered on.
When the transmitter is not
powered by the optional
PW-2412WU power pack (sold
separately), the DM OUT port
is not connected to a PoDM+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 optional PW-
2412WU power pack.

Problem Possible Cause(s) Corrective Action
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 software.
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-4KZ-202-C or
DM-TX-4KZ-302-C must be restored, do the following: From the Tools menu in the Crestron
Toolbox software, select Text Console and enter the following command:
