8x8 DigitalMedia™ Switcher

Crestron DM-MD8X8

The DM-MD8X8 is field-configurable to handle up to eight AV sources, and provide up to eight DM room outputs with expansion capability for even larger applications. A full selection of DM switcher input cards, DM transmitters*, and DM room controllers provides extensive connectivity throughout the home or office, supporting a complete range of analog and digital signal types — all through one switcher. User-friendly setup and troubleshooting tools are provided through the DM-MD8X8 front panel, or via Crestron Toolbox™ software, to simplify setup.

The DM-MD8X8 DigitalMedia Switcher is part of a High Definition Audio-Video distribution system that allows virtually any mix of AV sources to be distributed throughout the home from a centralized rack location using DigitalMedia.

* Future option, not currently available.

DigitalMedia™

Creating a professional HD AV distribution system means handling the challenges that come with HDMI. HDMI is the new standard for interfacing high-definition AV equipment, but despite its many benefits, it was not developed with multi-room distribution in mind. Crestron has developed DigitalMedia, the first complete HD AV distribution system that allows virtually any mix of HD AV sources to be distributed throughout the home from a centralized rack location.

DigitalMedia (DM) distributes uncompressed digital video and audio signals over a choice of CAT5e/Shielded Twisted Pair (STP)-based copper wiring or multi-mode fiber*. DigitalMedia manages all of the different signals and devices, matching each source's output to the capabilities of the selected display(s) without using scaling or compression. Every signal is preserved in its native video resolution and audio format, ensuring a pure, lossless signal path throughout.

Integrated Ethernet and USB HID distribution allows computers, media servers, and video game consoles to be installed out-of-sight and accessed from anywhere in the house. Crestron control is also built-in for controlling the displays and other room devices without additional wiring.

* Future option, not currently available.

Modular Architecture

The DM-MD8X8 features a modular architecture with eight input card slots and two quad-output card slots. Each card slot on the DM-MD8X8 is field-installable, allowing for easy and flexible system configuration with the ability to make changes to the system as needs change.

A wide selection of DM input cards are offered to support a complete range of digital and analog AV signal types. One or two output cards may be installed to feed up to eight DM Room Controllers (receivers) using either DigitalMedia (DM) Cable or CresFiber* fiber optic cable. DigitalMedia allows for cable lengths up to 450 feet (137 m) using DM cable, or 3280 feet (1 km) using CresFiber*. HDMI outputs are also available for connection to a centralized surround sound processor or video monitor.

* Future option, not currently available.

Output Expansion

An HDMI “pass-thru” output is provided on every input card to allow the inputs of up to five DM switchers to be daisy-chained, enabling the configuration of very large distribution systems with many DM outputs.

Versatile Audio Routing

HDMI is the key to handling all the latest 7.1 surround sound formats like Dolby® TrueHD and DTS-HD Master Audio. Great for your high-end home theater, but how do you share that same source with other audio zones in the house?

DigitalMedia allows for the simultaneous distribution of multi-channel surround sound (i.e. Dolby® TrueHD and DTS-HD Master Audio) and two-channel stereo signals from the same HDMI source. Equipped with a DMC-HD-DSP input card, the DM-MD8X8 employs onboard DSP processing to derive a stereo down-mix from the original multi-channel signal. Both signals can be routed separately or simultaneously from any of the switcher’s DM outputs, allowing either signal to be selected for output at each DM receiver location.

The switcher also converts the digital stereo signal to analog to enable sharing with every other room in the house via an AAE, CNX-PAD8A, or other multi-room audio distribution system. The DM-MD8X8 also allows surround sound processors and amplifiers to be located centrally instead of at the display location using optional local HDMI outputs.

Computer Compatibility*

Besides handling every available HDTV format supported by HDMI, DigitalMedia also supports the distribution of DVI and RGB computer signals, and is fully compatible with DVI computer monitors up to 1920 x 1200 WUXGA.

*DVI connectivity is currently enabled via HDMI input/output ports using third-party adapters; DVI/RGB input card coming soon.

Built-in Ethernet Switch

DigitalMedia also carries 10/100 Ethernet to each room controller, supporting streaming media for multimedia devices, or providing LAN connectivity for any room device that requires Ethernet or Internet access. Its Gigabit Ethernet connection to the external LAN helps maximize bandwidth for each network port. Ethernet is also utilized internally by the Crestron control bus to manage all of the DM devices in the system and provide display control in each room.

USB HID Switch

DigitalMedia lets you centralize all HD sources – not just television receivers and DVD changers, but also media servers, computers, and even video game consoles. Built-in USB HID (Human Interface Device) signal routing allows USB HID compatible keyboards, mice, and game controllers to be connected at each display location, extending their signals through to the centralized equipment via USB HID ports provided on select switcher input cards.

EDID Format Management

Using HDMI provides a variety of video and audio formats to keep track of, and chances are not every device in a system supports all of the same formats. In a typical one-room system, HDMI attempts to resolve this confusion using EDID. When two HDMI devices are connected together, the receiving device (a display or surround sound processor) uses EDID to announce its format capabilities to the source device (a TV tuner or video player), which in turn configures itself to output the most effective format that both devices can support.

However, serious conflicts arise in a facility filled with different displays and audio systems. For instance, the Blu-ray player that’s feeding a 1080p projector in the theater may restrict itself to a lower resolution, or even shut off completely, if

Operations Guide – DOC. 6755A

8x8 DigitalMedia™ Switcher: DM-MD8X8 • 3

8x8 DigitalMedia™ Switcher

Crestron DM-MD8X8

someone decides to view the same signal on the 32” TV in the bedroom. Instead of listening to a 7.1 Dolby TrueHD format supported by a high-end theater sound system, the listening experience may be limited to Dolby 5.1, or even stereo sound.

The DM-MD8X8 uses EDID to prevent such conflicts, assessing the formats supported by each system device, and then allowing the installer to assign compatible devices in logical arrangements. Conflicting combinations can be prohibited so only the optimum signal formats get delivered to each display and audio system in the house.

QuickSwitch HD™ Technology

Many content providers are using a copy-protection scheme called HDCP to protect products against unauthorized copying. To view HDCP encrypted content in full high-definition requires the source device to “authenticate” every display and signal processor through an HDMI connection before delivering an output signal. This process occurs every time any HDMI signal is switched, causing a complete loss of signal for up to 15 seconds whenever a new source or display is selected anywhere in the house.

Crestron’s QuickSwitch HD technology eliminates this issue by maintaining a constant HDCP connection with each HDMI device in the system. By eliminating the need to re-authenticate each time a different source or display is selected, QuickSwitch HD achieves very fast switching of HDMI signals.

HDCP Key Management

Another aspect to HDCP is its use of “keys” to manage the handshaking that occurs between any two devices. Every HDMI source device has a limit to how many downstream devices it can support, determined by the number of HDCP keys it has available. Rarely is that limit advertised or specified by the manufacturer or service provider, so connect too many displays or processors and the source will simply stop outputting a signal without warning.

To prevent such surprises, the DM-MD8X8 tests the HDCP limits of each HDMI source, allowing the installer to configure the system around any limitations, or substitute a different component.

CEC Signal Management

The primary objective of every Crestron system is to enable precisely the control desired for a seamless user experience. To ensure this outcome, the DM-MD8X8 intercepts the CEC signals that many HDMI devices automatically generate, preventing any unwanted commands from being executed – like a Blu-ray player attempting to turn off the video display when it gets turned off, or a DVD player trying to pause the other players in the system when it is playing. Through proper CEC management, DigitalMedia allows you to take control of each device as you like.QuickSwitch HD™ Technology

Easy Setup

Via the front panel or using Crestron Toolbox software, every step of the DM-MD8X8’s setup process is designed to be quick and easy, configuring inputs and outputs automatically while letting the installer make intelligent design decisions along the way. The switcher tests and measures the length of each DM cable, automatically making the appropriate calibrations for optimal signal transmission to every room. With DigitalMedia, an entire 8x8 system can be commissioned in approximately 15 minutes.

Setup

DigitalMedia Wiring

Connections between DigitalMedia Switchers and DigitalMedia Room Controllers can be made using a variety of wiring solutions. For optimum performance, Crestron recommends Crestron DigitalMedia cable, CresFiber fiber optic cable (available 1Q, 2009), or CresFiber Pro fiber optic cable (available 1Q, 2009).

When wiring the DigitalMedia network, consider the following:

•Use Crestron Certified Wire.

•Use Crestron power supplies for Crestron equipment.

•Provide sufficient power to the system.

CAUTION: Insufficient power can lead to unpredictable results or damage to the equipment. Please use the Crestron Power Calculator to help calculate how much power is needed for the system (www.crestron.com/calculators).

For information on connecting Ethernet devices in a Crestron system, refer to the latest version of the Crestron e-Control® Reference Guide (Doc. 6052), which is available for download from the Crestron website (www.crestron.com/manuals).

DigitalMedia Cable

The Crestron DigitalMedia cable contains two CAT5E cables (one shielded, one unshielded) and one DMNet cable in triamese jackets. Installation of any DigitalMedia device is as simple as connecting DigitalMedia cable from the output of the DigitalMedia switcher to the input of a DigitalMedia device such as a DM-RMC-100 DigitalMedia Room Controller. For more information, refer to the latest version of the Crestron DigitalMedia Design Guide (Doc. 4789), which is available for download from the Crestron website (www.crestron.com/digitalmedia).

NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2” (0.84-1.27 cm) when making a connection. The twists are critical to canceling out interference between the wires.

The maximum transmission distances between repeaters are determined by the video resolution sent over the wires. The total distance that video can be sent using repeaters is shown in the following table for CAT5e/Shielded Twisted Pair (STP) cable and DigitalMedia cable. While up to three repeaters may be used to extend the transmission distance, the aggregate cable length of a signal path originating at a DM-MD8X8 and terminating at a DM-RMC-100 DigitalMedia Room Controller must not exceed 450 feet (137.1 meters) when using DigitalMedia cable (400 feet (121.9 meters) when using CAT5E/STP cable). The following table shows the maximum cable lengths allowed between repeaters when using DigitalMedia cable or CAT5E/STP cable.

HDCP Signal Path

Sources using HDCP limit the number of display devices it can transmit to while simultaneously limiting the depth of devices in the signal path. Too many devices or greater-than-allowed depth in a signal path (from source to display) may create problems with displaying of audio and video content. The HDCP specification states that the maximum depth of devices between source and display is six. Some examples are shown in the following diagram.

Ethernet Setup

The DigitalMedia switchers are designed to control the Ethernet settings of lightweight DM devices around them in order to reduce the amount of IP configuration necessary and make the certain DM devices swappable without reconfiguration.

		The DigitalMedia switchers have the ability to operate in DHCP or Static IP address
	IP Configuration
		mode. In addition, the DM switchers control the IP addressing information for input
		cards that have Ethernet capabilities as well as neighboring DigitalMedia devices.
		When the DM switcher is set to DHCP mode, these cards and DM devices will also
		be set to DHCP mode. When the DM switcher is set into Static IP mode, these cards
		and DM devices will receive a Static IP configuration equivalent to the DM
		switcher’s IP address plus their slot number. This configuration is sent when the
		DM-MD8X8 starts up.
		Example:
		A DM Switcher is set to IP address 192.168.1.30 The IP mask is 255.255.255.0 and
		the default router is 192.168.1.1. The HDMI input card on slot 3 would be set to IP
		address 192.168.1.33 and receive the same IP mask and default router as the DM
		switcher.
		Since there can be up to 32 slots in the DigitalMedia switcher, the last octet in the
		DM switcher IP address may not be set higher than 222. Otherwise the device on slot
		32 would not be able to receive a valid static IP configuration.
		DigitalMedia devices that send this IP configuration are the DM-MD8X8 and the
		DM-MD16X16.
		DigitalMedia devices that receive this IP configuration are the DMC-HD,
		DMC-HD-DSP, DMC-DVI, DM-RMC-100, DM-RMC-100-F, DM-TX-100,
		DM-TX-200, DM-TX-205, and DM-TX-210.
		If two DigitalMedia switchers were connected to one another via a DMC-CATO
		output card and DMC-CAT input card, each switcher would maintain control over its
		own IP configuration.
		DigitalMedia devices that receive their IP address configuration via the switcher can
	IP Table Setup
		also receive their IP table configuration from the DM switcher.
		For more information, refer to “IP Table Options” on page 48.
		Identity Code
		The IP ID can be set from the front panel using Installer Tools or in the
		DM-MD8X8’s IP table using Crestron Toolbox™. For information on using Installer
		Tools to set the IP ID, refer to “Control System IP ID” on page 33. For information
		on setting an IP table, refer to the Crestron Toolbox help file. The IP IDs of multiple
		DM-MD8X8 devices in the same system must be unique.
		When setting the IP ID, consider the following:
		• The IP ID of each unit must match an IP ID specified in the SIMPL™
		Windows® program.
		• Each device using IP to communicate with a control system must have a
		unique IP ID.
		Installation
		The DM-MD8X8 should be used in a well-ventilated area. The venting holes should
	Ventilation
		not be obstructed under any circumstances.
		To prevent overheating, do not operate this product in an area that exceeds the
		environmental temperature range listed in the table of specifications. Consider using
		forced air ventilation and/or increasing the spacing between units to reduce
		overheating. Consideration must be given if installed in a closed or multi-unit rack
