Intercom Video Distribution System Crestron C2N-IVDS24x24

NET

This LED illuminates when communication between the control system and the

IVDS is established (the unit is polled on the network). Illumination indicates that

the SIMPL Windows program currently loaded has a network device defined at the

same Net ID as the IVDS. The LED flashes when communication with the processor

occurs.

SETUP LED and Pushbutton

The IVDS is TSID ready. The SETUP pushbutton and its associated LED are used

for setup of the unit’s network ID during the initial configuration of a Cresnet®

system or when the device is being added/replaced. Refer to “Method B (Touch

Settable IDs)” on page 9 for detailed information.

Industry Compliance

As of the date of manufacture, the IVDS has 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.

Setup

Network Wiring

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).

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

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

40,000

Where:

The required wire gauge should be chosen such that the resistance value is less than

the value calculated in the resistance equation. Refer to the table after this paragraph.
