Introduction
Operations Guide – DOC. 6538A
Features and Functions
• 16 input by 16 output QuickMedia matrix switcher
• QuickMedia technology carries high-resolution RGB, video, stereo audio and microphone signals up to 450 feet using either Crescat-QM-P or Crescat-QM-NP QuickMedia cable from Crestron ®
• Audio breakaway can route audio signals independent of video signals
• Expands number of inputs and outputs of existing QuickMedia systems
• Front panel buttons can be used to operate switcher; buttons can be custom labeled
• Front panel buttons can be disabled for security
• Control system program can operate the switch via digital, analog, and serial control

The QM-MD16X16 is a 16x16 QuickMedia (QM) matrix switcher designed to provide routing of up to 16 inputs from QuickMedia Wall Plates and FlipTop Boxes to any of 16 QuickMedia Receivers. All signal routing is provided over CAT5e type cable* via Crestron's exclusive QuickMedia transport, supporting the distribution of high-resolution RGB, video, stereo audio and microphone signals up to a total of 450 feet end-to-end. Audio breakaway capability allows audio signals to be routed independent of video signals.
Up to two QuickMedia Matrix Switchers and Distribution Centers may be cascaded in a given QuickMedia signal path* to support larger system configurations. For instance, a QM-MD16X16 may be used to expand the input capacity of a
QM-MD7X2, or multiple QM Matrix Switchers can be combined to support applications such as room-combining with numerous inputs and outputs.
* For QuickMedia wiring use CresCAT-QM, CresCAT-IM, or quality CAT5e/CAT6 cable with a delay skew of ≤15ns per 100m; the maximum aggregate cable length and delay skew between any
QM transmitter (origination point) and QM receiver (endpoint) is 450 ft (137 m) and 22 ns; a maximum of two QM midpoint devices may be inserted in a given QM signal path; exceptions apply, refer to each respective product manual for full detail.

Complete system operation can be made transparent to the end-user with all signal routing occurring under the command of the MediaManager control system. Control and monitoring of the QM-MD16X16 is also possible independent of the control system using its front panel pushbuttons and LEDs. Customizable label strips are provided to easily designate inputs and outputs by name using Crestron Engraver software or standard 3/8" tape labels. For security, the front panel controls can be locked out.
Every QuickMedia port on the rear panel is accompanied by a Cresnet port with 24V
DC power distribution built in for termination of QuickMedia and Cresnet wiring. A built-in Cresnet hub provides four isolated segments, each supporting 3000 feet of cabling and approximately 25 Cresnet devices.

• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
NOTE: If rack mounting is not required, rubber feet are provided for tabletop mounting or stacking. Apply the feet near the corner edges on the underside of the unit.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
To install the ears:
1. There are screws that secure each side of the QM-MD16X16 top cover.
Using a #2 Phillips screwdriver, remove the three screws closest to the front panel from one side of the unit. Refer to the diagram following step 3 for a detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated by the screws in step 1.
3. Secure the ear to the unit with three screws from step 1, as shown in the following diagram.
Ear Attachment for Rack Mounting
Stacking
4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the opposite side.
Four “feet” are provided with the QM-MD16X16 so that if the unit is not rack mounted, the rubber feet can provide stability when the unit is placed on a flat surface or stacked. These feet should be attached at the corners of the bottom of the unit prior to the hookup procedure.

NOTE: The QM-MD16X16 can only be powered by the 4-position terminal block connector labeled NET. Power cannot be supplied from network devices that are connected to the mini-terminal block connectors.
NOTE: The Y and Z Cresnet data lines from the network are connected to the NET connector, which is internally wired to the 4-position mini-terminal block connector for each QM connector.
NOTE: In the configuration shown, the C2N-SPWS300 can operate in the “PWR
ON” position or the “PWR OFF SLAVE” position. For more information, refer to the latest revision of the C2N-SPWS300 System Power Supply Operations Guide
(Doc. 8190).
NOTE: Power to the QM ports on the QM-MD16X16 can be applied using other configurations. The total power usage of each port group must not exceed the port group’s available input power. For example, if 75 watts is supplied to QM inputs 1 through 4, the total power consumption for those ports cannot exceed 75 watts.
The QM-MD16X16 has an internal four-segment Cresnet hub for routing Cresnet data. The segments are separated as shown in the following diagram.
Segment 3
Segment 4
Each segment operates independent of each other to allow the QM-MD16X16 to continue functioning in the event of a hub segment experiencing an electrical short or a device error.
Use Crestron Engraver software to print custom labels for the QM-MD16X16’s front panel buttons and LEDS. Crestron recommends printing on 100-pound paper. Paper weighing less than 100 pounds will tend to crumple while sliding in, while paper weighing more than 100 pounds may not fit.

Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the QM-MD16X16, it is recommended to use SystemBuilder QM Tools software for configuring a
QuickMedia system.
SIMPL Windows is Crestron’s premier software for programming Crestron control systems. It is organized into two separate but equally important “Managers”.
Configuration Manager is the view where programmers “build” a Crestron control system by selecting hardware from the Device Library.
• To incorporate the QM-MD16X16 into the system, drag the QM-MD16X16 from the Cresnet Control Modules | QM Series folder of the Device Library and drop it in the System Views.

Uploading and Upgrading
Crestron recommends using the latest programming software and that each device contains the latest firmware to take advantage of the most recently released features.
However, before attempting to upload or upgrade it is necessary to establish communication. Once communication has been established, files (for example, programs or firmware) can be transferred to the control system (and/or device).
Finally, program checks can be performed (such as changing the device ID or creating an IP table) to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the QM-MD16X16; refer to the
Crestron Toolbox help file for details. There is a single method of communication: indirect communication.

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. 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
( http://www.crestron.com/calculators ).
When calculating the length of wire for a particular Cresnet run, the wire gauge and the Cresnet power usage of each network unit to be connected must be taken into consideration. Use Crestron Certified Wire only. If Cresnet units are to be daisychained on the run, the Cresnet power usage of each network unit to be daisychained must be added together to determine the Cresnet power usage of the entire chain. If the unit is home-run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire run. The wire gauge and the Cresnet power usage of the run should be used in the following equation to calculate the cable length value on the equation’s left side.
Cable Length Equation
L <
40,000
R x P
Where: L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM )) or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM ))
P = Cresnet power usage of entire run (or chain)
Make sure the cable length value is less than the value calculated on the right side of the equation. For example, a Cresnet run using 18 AWG Crestron Certified Wire and drawing 20 watts should not have a length of run more than 333 feet. If Cresnet HP is used for the same run, its length could extend to 1250 feet.
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One twisted pair is the +24V conductor and the GND conductor and the other twisted pair is the Y conductor and the Z conductor.
When daisy-chaining Cresnet units, strip the ends of the wires carefully to avoid nicking the conductors. Twist together the ends of the wires that share a pin on the network connector and tin the twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining screw. Repeat the procedure for the other three conductors.
For larger networks (i.e., greater than 28 network devices), it may become necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality throughout the network. Also, for networks with lengthy cable runs it may be necessary to add a
Hub/Repeater after only 20 devices.
