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: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit's supply
input should be considered to prevent overloading the wiring.

Ground Wire Connections

Proper grounding is required. Connect the ground from the QM transmitter
(QM-FTCC) to earth ground. Connect the Cresnet shield at the QM-RMCRX-BA to
the chassis ground provided on the QM-RMCRX-BA. The QM-RMCRX-BA chassis
must also be connected to an earth ground (building steel). Refer to the following
grounding diagram.
