DM-RMC-4K-100-C-1G:
Wall Plate 4K DigitalMedia 8G+®
Receiver and Room Controller 100
Introduction
The Crestron®DM-RMC-4K-100-C-1G functions as a DigitalMedia 8G+®receiver and
control interface, providing a single HDMI®output as well as RS-232 and IR control ports.
In addition to DM 8G+®compatibility, the DM-RMC-4K-100-C-1G is also compatible with
the HDBaseT®standard, allowing it to be connected directly to an HDBaseT certified
source. For additional information about the DM-RMC-4K-100-C-1G, refer to the
DM-RMC-4K-100-C-1G DO Guide (Doc. 7707) at www.crestron.com/manuals.
This guide provides information about the following:
•Physical description of the front and rear panels of the DM-RMC-4K-100-C-1G
•Communication of the DM-RMC-4K-100-C-1G with a control system
•HDCP 2.2 compliance

Physical Description
This section provides information about the connectors, controls, and indicators on the front
and rear panels of the DM-RMC-4K-100-C-1G.
Front Panel
The following illustration shows the front panel of the DM-RMC-4K-100-C-1G.

PWR:
Green LED, indicates operating power supplied via PoDM or local power pack

VIDEO:
Green LED, indicates video signal presence at the HDMI output

IR OUT:
2-pin 3.5 mm detachable terminal block comprising IR/serial port;*
IR output up to 1.1 MHz;
1-way serial TTL/RS-232 (0-5 volts) up to 19200 baud

COM:
3-pin 3.5 mm detachable terminal block;
Bidirectional RS-232 port;*
Up to 115.2k baud, software handshaking support

HDMI OUT:
19-pin Type A HDMI female;
HDMI digital video/audio output (DVI compatible)
NOTE:
The HDMI OUT port requires an appropriate adapter or interface cable to
accommodate a DVI signal. The CBL-HD-DVI interface cable is available separately.
*The IR OUT and COM ports are not supported when the DM-RMC-4K-100-C-1G connects directly to a
DM-TX-4K-100-C-1G; however, video will pass through properly. The IR OUT and COM ports are supported only
when the DM-RMC-4K-100-C-1G connects to an Ethernet-enabled DigitalMedia™ transmitter or switcher that is
addressable from a Crestron control system. When the DM-RMC-4K-100-C-1G connects to a DigitalMedia
switcher, the switcher must be in Private Network Mode (PNM).

8-pin RJ-45 female, shielded, with two LEDs;
DM 8G+ input, HDBaseT standard compliant;
PoDM and HDBaseT PoE PD (Powered Device) port;
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 DM link status;
Solid amber LED indicates HDCP video;
Blinking amber LED indicates non-HDCP video
NOTE:
Receiving PODM requires connection to a switcher or other equipment that has
a PoDM PSE (Power Sourcing Equipment) port. Any wiring that is connected to a
PoDM 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 IN port connects directly to a DM-TX-4K-100-C-1G, simple
pass-through of CEC is supported. If the DM IN port connects to an Ethernet-enabled
DigitalMedia™ transmitter or switcher that supports CEC over HDBaseT connectivity,
full management of CEC between the locally connected HDMI device and a control
system is supported.

Communication with a Control System
Unlike most DigitalMedia endpoints, the DM-RMC-4K-100-C-1G does not support an
Ethernet-based CIP connection with a control system. In order to communicate with a
control system, the DM-RMC-4K-100-C-1G must connect to a DigitalMedia switcher or
transmitter that supports a CIP connection with the control system. The DigitalMedia
switcher or transmitter communicates with the DM-RMC-4K-100-C-1G via a serial
communications path in the DigitalMedia link.
HDCP 2.2 Compliance
The DM-RMC-4K-100-C-1G 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
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.”

Troubleshooting
The following table provides troubleshooting information. If further assistance is required,
contact a Crestron customer service representative.
DM-RMC-4K-100-C-1G Troubleshooting
TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION
The video is not being
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.
The video is intermittent. The HDMI cable connections are
faulty.
Verify that each end of the
cable is connected properly.
The DM-RMC-4K-100-C-1G
cannot establish a link to the
device that is connected to
the DM IN port. The DM link
status LED is off.
The cable connections are faulty. Verify that each end of the
cable is connected properly.
If necessary, check the cable
terminations.
The DM-RMC-4K-100-C-1G
does not remain powered on.
When the DM-RMC-4K-100-C-1G
is not being powered by the
included power pack, the DM IN
port is not connected to a PoDM
PSE port.
Ensure that the DM IN port is
connected to a PoDM PSE
port when not being powered
by the included power pack.
The video flickers or drops
when the
DM-RMC-4K-100-C-1G is
touched or when metal in the
vicinity of the device is
touched.
The DM-RMC-4K-100-C-1G is not
properly grounded.
Ensure that the
DM-RMC-4K-100-C-1G is
properly grounded.
