Product Details

Crestron DigitalMedia DM-TX-401-C Transmitter 401 - KVM / audio extender - 10Base-T, 100Base-TX

The DM-TX-401-C is a DM 8G+ transmitter and switcher that offers a versatile interface for computers and high-definition AV sources as part of a complete Crestron DigitalMedia system. In addition to DM 8G+, it is also compatible with HDBaseT specifications, allowing it to be connected directly to the input of an HDBaseT compliant display device. Compact and rack-mountable, the DM-TX-401-C connects to the head end or display location using a single CAT5e or Crestron DM 8G cable. It provides DisplayPort, HDMI, VGA, and analog video and audio inputs, plus Ethernet, RS-232, and IR control ports, and a USB HID host port for a total connectivity solution.

  • Enables device control via CEC, IR, RS-232, and Ethernet
  • Allows quick, easy setup and diagnostics
  • Advanced analog video processing
    Via the PC and Video inputs, the DM-TX-401-C employs advanced analog video processing with anti-aliasing and 3D comb filtering to ensure the reliable distribution of analog VGA and video sources. Built-in time base correction is also included to ensure optimal results for use with video tape players.
  • LAN connectivity
    Along with high-definition AV and control, DigitalMedia also integrates high-speed Ethernet networking for a total signal distribution solution. The DM-TX-401-C includes a 10/100 Ethernet port, providing a convenient LAN connection for a local network device.
  • Embedded device control
    The primary objective of every Crestron system is to enable precisely the control desired for a seamless user experience. The DM-TX-401-C includes built-in IR, RS-232, and Ethernet control ports to allow programmable control of the devices connected to it. But, it can also provide an alternative to such conventional control methods by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to the control system, the DM-TX-401-C 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 emitters.
  • Keyboard/mouse extender
    The DM-TX-401-C functions as a keyboard/mouse extender, allowing a USB HID-compliant keyboard and/or mouse to be connected to the front panel and used to control a computer or other component located at the central equipment rack or some other location.
  • EDID format management
    The DM-TX-401-C 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-401-C, ensuring reliable operation by instructing sources to output only the resolutions and formats that can be handled by the displays and system wiring.
