Crestron QM-DA QuickMedia™ Distribution Amplifier
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.
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-DA can be applied using other
configurations. The total power usage of each port group must not exceed the port
group’s available input power.
In the QM-DA-16, each of the three Cresnet hub segments operates independent of
the others to allow the QM-DA-16 to continue functioning in the event of one hub
segment experiencing an electrical short or a device error. (Refer to the following
illustration.)
