SETUP

This LED is the lone indicator on the back panel. The LED is intended for future use

and is not defined at the time of printing.

CNX-PVID8x4 Pushbuttons

There are two pushbuttons on the CNX-PVID8x4 (one on the front panel and one on

the back panel). The front panel SELECT pushbutton allows for local selection of

the boards (levels 1 through 4). Four indicators are used as feedback. The rear panel

SETUP pushbutton is for future use and is not defined at the time of printing.

Industry Compliance

As of the date of manufacture, the CNX-PVID8x4 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

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to

do so could cause equipment damage or void the Crestron warranty.

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 Cresnet run, the length of the run

and the power factor of each network 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 unit to be daisy-chained must be added together to determine the power factor

of the entire chain. If the unit is a home-run from a Crestron system power supply

network port, the power factor of that unit is the power factor of the entire run. 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

R = Resistance (refer to table below).

L = Length of run (or chain) in feet.

PF = Power factor of entire run (or chain).

R <

L x PF
