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-MD16X16. Power for the QM-MD16x16 is jumped from the Cresnet input on
the C2N-SPWS300.
