8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 ® 8X8 QuickMedia Matrix Switcher: QM-MD8X8 Introduction The QM-MD8X8 is an 8X8 QuickMedia matrix switcher designed to provide versatile routing of up to eight inputs from QuickMedia Wall Plates and FlipTop Boxes to any of eight QuickMedia Receivers.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Complete system operation can be made transparent to the end-user with all signal routing occurring smoothly under the command of the MediaManager control system. Control and monitoring of the QM-MD8X8 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.

8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Industry Compliance As of the date of manufacture, the QM-MD8X8 has been tested and found to comply with specifications for CE marking and standards per EMC and Radiocommunications Compliance Labelling. NOTE: This device complies with part 15 of the FCC rules.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Setup Network Wiring When wiring the Cresnet 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).
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 may experience a loss of quality over very long lengths of cable. This phenomenon is due to the added resistance and capacitance of longer cable lengths and is not peculiar to either Crestron and/or QuickMedia systems. To ensure sufficient bandwidth, the maximum aggregate cable length should not exceed 450 feet. The use of lower-resolution signals may allow increased cable length but must be tested by the installer with the sources to be used.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Installation Ventilation The QM-MD8X8 should be used in a well-ventilated area. The venting holes should 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 incrementing the spacing between units to reduce overheating.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Ear Attachment for Rack Mounting (this image shows a 1RU device) USE COVER SCREWS 4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the opposite side. Four “feet” are provided with the QM-MD8X8 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 prior to the hookup procedure.

C2Net Device, Slot 5 • Additional QM-MD8X8 devices are assigned different Net ID numbers as they are added. • If necessary, double click a device to open the “Device Settings” window and change the Net ID, as shown in the following figure.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 “QM-MD8X8 Device Settings” Window • Program Manager The ID code specified in the SIMPL Windows program must match the Net ID of each unit. Refer to “Identity Code” on page 13. Program Manager is the view where programmers “program” a Crestron control system by assigning signals to symbols. The symbol can be viewed by double clicking on the icon or dragging it into Detail View. Each signal in the symbol is described in the SIMPL Windows help file (F1).
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 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).
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 To upgrade QM-MD8X8 firmware via Crestron Toolbox: • Establish communication with the QM-MD8X8 and display the “System Info” window. • Select Functions | Firmware… to upgrade the QM-MD8X8 firmware. NOTE: QM-MD8X8s that are identified as “QM-MD8X8” require firmware version 4.x or lower. QM-MD8X8s that are identified as “QM-MD8X8-HB” require firmware version 5.0 or greater.

System Mode Switching functions controlled by control system program. Press the SYS button to activate System mode. • Local Mode When in System mode, pressing input or output buttons shows source/destination information. Switching functions controlled by front panel buttons. Press LOCAL to activate Local mode (accompanying LED will flash).
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 To disable routing to a specific output, press the corresponding output button again. The LED will turn off. If a button press will result in changing the current routing, the ENTER LED will flash rapidly. 5. Press ENTER to make the connection(s) shown on the front panel. The ENTER LED will turn off. Changes made on the front panel are made only after the ENTER button is pressed. If you do not press ENTER, the connection is not made.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 Problem Solving Troubleshooting The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative. QM-MD8X8 Troubleshooting TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION Device is not communicating with the network. Use Crestron Toolbox to poll the network. Verify network connection to the device.
8X8 QuickMedia® Matrix Switcher Crestron QM-MD8X8 chained 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.
