Industry Compliance
As of the date of manufacture, the touchpanel have been tested and found to comply
with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling (N11785).
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: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
CAUTION: Possible equipment damage if miswired.
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate to your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
NOTE: Do not power up system until all wiring is verified. Care should be taken to
ensure data (Y, Z) and power (24, G) connections are not crossed.
NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the power factor of each Cresnet unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the power factor of
each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation

Where:
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
