FlipTop Media Center
Setup
14 • FlipTop Media Center: QM-FTMC
SETUP LED and Pushbutton
The QM-FTMC is Touch-Settable ID-ready. A SETUP pushbutton and
associated LED are located on the bottom of the unit next to the Cresnet
connectors. The SETUP pushbutton and its associated LED are used for setting
a units network ID during the initial configuration of a Cresnet system or when
the device is being added/replaced.
Industry Compliance
As of the date of manufacture, the QM-FTMC 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. Operation is
subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Network Wiring
CAUTION: In order to ensure optimum performance over the full range of
your installation topology, Crestron Certified Wire, and only Crestron Certified
Wire, may be used. Failure to do so may incur additional charges if support is
required to identify performance deficiencies as a result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure
to do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. 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
(http://www.crestron.com/calculators).
When calculating the length of wire for a particular Cresnet run, the wire gauge
and the Cresnet power usage of each network unit to be connected must be taken
into consideration. Use Crestron Certified Wire only. If Cresnet units are to be
daisy-chained on the run, the Cresnet power usage of each network unit to be
daisy-chained must be added together to determine the Cresnet power usage of
the entire chain. If the unit is a 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. The wire gauge and the Cresnet power usage of the run should be
used in the following equation to calculate the cable length value on the
equation's left side.
Cable Length Equation
40,000
Where:
L <
R x P
Crestron QM-FTMC
L = Length of run (or chain) in feet.
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM
P = Cresnet power usage of entire run (or chain).
