4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the
opposite side.
Stacking
Four “feet” are provided with the QM-MD4X4 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.
Hardware Hookup
Connect the Device
Make the necessary connections as called out in the illustration that follows this
paragraph. Refer to “Network Wiring” on page 12 before attaching the 4-position
terminal block connector. Apply power after all connections have been made.
When making connections to the QM-MD4X4, use Crestron power supplies for
Crestron equipment.

NOTE:
Ensure the unit is properly grounded.
NOTE:
For optimum performance, Crestron strongly recommends using
CresCAT-QM cable, available from Crestron. Other high-quality/low skew
CAT5e/CAT6 wiring may also be used with varying performance.
The required 24 VDC power for each group of QM inputs and QM outputs can be
supplied in a variety of ways. The following wiring diagram suggests one method of
applying 24 VDC power to the QM ports. In this configuration, the C2N-SPWS300
can supply up to 75 watts of power to each group of QM ports to ensure that
sufficient power is available for QM devices that are connected to the QM-MD4X4.
The C2N-SPWS300 can also supply the power required by the QM-MD4X4.
