any other device that provides contact closure to detect the power status of a high-
power device such as a television.
NET
This four-pin connector is used to connect to other four-wire devices in the Cresnet
system. This connector must be attached to power the unit and communicate with the
control system.
LED Indicators
The CNXRMC provides three LED indicators. The PWR (Power) indicator goes on
when the unit is supplied with 24 volts DC from the network. The NET indicator is
typically on when the unit is polled on the network (some flashing may occur). The
NET LED indicates that the current program has a network device defined at the
same Net ID as the CNXRMC. (The SETUP indicator and button are reserved for a
function that is to be available in the future.)
VIDEO INPUT COMP 1, 2, 3
The CNXRMC provides three potentiometers (pots) that can be adjusted to
compensate for CAT5 cable run lengths. Refer to “Video Input Compensation” on
page 8 for the adjustment procedure.
Industry Compliance
As of the date of manufacture, the CNXRMC 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) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network 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 resistance equation on the next page to calculate the
value on the right side of the equation.
