DigitalMedia 8G+® 4K60 4:4:4 HDR
Receiver and Room Controller
Introduction
The Crestron® DM-RMC-4KZ-100-C is a DigitalMedia 8G+® receiver and room controller
that supports full 4K60 4:4:4 and high dynamic range (HDR) video signals. Via a CATx
cable, the DM-RMC-4KZ-100-C connects to a DigitalMedia™ switcher or transmitter or
to an HDBaseT® source. Connection to a display device is provided by a single HDMI®
output. In addition, built-in RS-232, IR, and Ethernet control ports enable programmable
control of the display device via a control system.

used) Red LED indicates that the SETUP button is pressed and times out
automatically;
Recessed push button for Ethernet setup
NOTE: The default static IP address of the DM-RMC-4KZ-100-C is 192.168.1.250.
Ground ( ): 6-32 screw, chassis ground lug
HDMI OUT: HDMI Type A connector, female;
HDMI digital video/audio output (DVI compatible)
NOTES:
•The HDMI OUT port requires an appropriate adapter or interface cable to
accommodate a DVI signal. CBL-HD-DVI interface cables are available
separately.
•4K60 4:4:4 performance and HDR support require the use of HDMI cables and
couplers with a minimum TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30
4:4:4 performance is acceptable, cables and couplers with a minimum bandwidth
of 10.2 Gbps may be used. Performance may be reduced when inserting multiple
cables and couplers inline.
HDMI OUT LED: Green LED, indicates that an HDMI signal is detected at the
HDMI output
DM IN: 8-pin RJ-45 female, shielded;
DM 8G+® input, HDBaseT standard compliant;
PoDM PD (powered device) port (HDBaseT PoE compatible);
Connects to the DM 8G+ output of a DM® switcher, transmitter, or other DM® device,
or to an HDBaseT device via CAT5e, Crestron DM-CBL-8G, or Crestron
DM-CBL-ULTRA cable;
Green LED indicates that a DM or HDBaseT link is established;
Solid amber LED indicates that HDCP video is detected;
Flashing amber LED indicates that non-HDCP video is detected.
NOTE: In order to receive PoDM, the DM IN port requires connection to a
DigitalMedia switcher or other DM equipment that has a PoDM PSE (power sourcing
equipment) port. In order to receive HDBaseT PoE, the DM IN port requires
connection to equipment that has an HDBaseT PoE PSE port. Wiring that connects
to a PoDM or HDBaseT PoE PSE port is for intrabuilding use only.
24 VDC 0.75A MAX: 2.1 x 5.5 mm DC power connector;
24 VDC power input;
Power pack included
Power LED: Green LED, indicates that power is being applied via PoDM, HDBaseT
PoE, or the included power pack

Connection to a Third-Party HDBaseT
Transmitter
The DM-RMC-4KZ-100-C is compliant with the HDBaseT standard, enabling direct
connection to other HDBaseT certified equipment. Via the DM 8G+ input, the
DM-RMC-4KZ-100-C can be connected directly to a third-party HDBaseT compliant
source without requiring a DigitalMedia transmitter.
SIMPL Windows allows an HDBaseT transmitter to be added to the
DM-RMC-4KZ-100-C. The HDBaseT transmitter adds a COM port to the
DM-RMC-4KZ-100-C and enables two-way serial communication.
To add a third-party HDBaseT transmitter to the DM-RMC-4KZ-100-C, use SIMPL
Windows. An overview of the necessary steps follows.
NOTE: For detailed information, refer to the SIMPL Windows help file.
HDBaseT Transmitter Slot (Slot 5)
When the third-party HDBaseT transmitter is added to slot 5, the HDBaseT Transmitter
symbol adds a COM port to the device and enables two-way serial communication.

HDCP 2.2 Compliance
The DM-RMC-4KZ-100-C is 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
requires HDCP 2.
•Any product that supports HDCP 2 also supports HDCP 1.
•HDCP 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.
•There 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-RMC-4KZ-100-C Troubleshooting
PROBLEM POSSIBLE CAUSE(S) CORRECTIVE ACTION(S)
Video is not displayed, but
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.
The 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 receiver 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 receiver cannot
establish a link to the device
that is connected to the DM
IN port. The DM IN ink
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 receiver does not
remain powered on.
When the receiver is not powered by
the included power pack, the DM IN
port is not connected to a PoDM or
HDBaseT PoE PSE port.
Ensure that the DM IN 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 software.
If the receiver connects to a
DigitalMedia switcher, the receiver
does not connect to the correct DM
output port of the switcher.
Ensure that the receiver connects
to the correct DM output port of
the switcher.
The video flickers or drops
when the receiver is
touched or when metal in
the vicinity of the device is
touched.
The receiver is not grounded properly. Ensure that the receiver is
grounded properly.
NOTE: If, for any reason, the factory default setting of the DM-RMC-4KZ-100-C must
be restored, do the following: From the Tools menu in the Crestron Toolbox software,
select Text Console and enter the following command:
