Crestron DM-TX-200    DigitalMedia™ CAT Transmitter 200 
There are four options for connecting USB devices to the USB port on the 
DM-TX-200: 
1. One mouse 
2. One keyboard 
3.  One mouse and one keyboard connected through a USB hub 
4.  One composite USB device 
EDID Format Management 
The DM-TX-200 allows for management of the EDID (Extended Display 
Identification Data) information that passes between the display devices and input 
sources in the system. Using Crestron Toolbox™ software, the format and resolution 
capabilities of each device can be assessed and managed through the DM-TX-200, 
ensuring reliable operation by instructing sources to output only the resolutions and 
formats that can be handled by the displays and system wiring. 
CEC Embedded Device Control 
The primary objective of every Crestron system is to enable precisely the control 
desired for a seamless user experience. DigitalMedia provides an alternative to 
conventional IR and RS-232 device control by harnessing the CEC (Consumer 
Electronics Control) signal embedded in HDMI. Through its connection to the 
control system, the DM-TX-200 provides a gateway for controlling the connected 
source device right through the HDMI connection, potentially eliminating the need 
for any dedicated control wires or IR probes. Through proper CEC signal 
management, DigitalMedia allows you to take control of each device in the system 
as you like. 
Compact and Versatile 
The DM-TX-200 is designed to be placed on a shelf or mounted on a flat surface. It 
is compact enough to fit discreetly inside a presentation lectern or beneath a table 
and can even be concealed inside a divided Wiremold
®
 6000 Series Raceway. An 
array of indicators on the front of the DM-TX-200 provides for easy setup and 
troubleshooting, verifying the status of connections and signal activity at a glance. 
Advanced configuration is enabled through Crestron Toolbox software. 
A Digital Upgrade for Legacy Systems 
The DM-TX-200 also affords a perfect signal converter for integrating DigitalMedia 
with analog-based systems like Crestron MPS, QuickMedia
®
 and the CEN-RGBHV 
series (all sold separately). A simple HD15 VGA cable connected between the output 
of an MPS system and the input of the DM-TX-200 allows every RGB, component, 
S-video and composite video input on the MPS to be converted to DigitalMedia*. 
Analog audio is converted similarly through a simple unbalanced stereo audio cable. 
The DM-TX-200’s HDMI input may also be used to expand the input capabilities of 
the MPS system to handle digital AV sources. 
*  The RGB input can accept component, composite and S-video signals via direct interface to Crestron 
MPS Series products (sold separately) or through an appropriate adapter (not included). Input sync 
detection is not provided for composite or S-video signal types through the RGB connection.
