SETUP

Network Wiring

When wiring the Cresnet network, consider the following:

• Use Crestron Certified Wire.

• Use Crestron power supplies for Crestron equipment.

• Provide sufficient power to the system.

CAUTION: 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 (www.crestron.com/calculators).

For networks with 20 or more devices, use a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality.

For more details, refer to "Check Network Wiring" on the next page.

Identity Code

The Net ID of the C2N-IO has been factory set to A5 (with a mechanical setting of 00).

NOTE: The NET ID controls on the C2N-IO are factory set to 00. This allows changing

the Net ID with Crestron Toolbox™ (optional).

The Net ID of the C2N-IO can be set using one of two methods:

• Manual setting: Set the two NET ID controls (from 03 to FE) to match the Net ID in the SIMPL Windows program.

• Touch-settable ID: Set the two NET ID controls to 00 and set the Net ID using Crestron Toolbox. This is the factory setting. For more details, refer to the Crestron Toolbox help file.

When setting the Net ID, consider the following:

• The Net ID of each unit must match an ID code specified in the control system program.

• Each network device must have a unique Net ID.

Installation

The C2N-IO can be installed inside a standard 2-gang US or UK electrical box using the included Dual Lock fastener or mounted to another other suitable location using the included mounting bracket.

To use the included mounting bracket, use the included screws to attach the mounting bracket as shown in the following illustration. The only tool required is a #1 Phillips screwdriver.

Attach Mounting Bracket to C2N-IO (Optional)

NOTE: Screws to secure the C2N-IO to a surface are not included.

Hardware Hookup

Make the necessary connections as shown in the illustration that follows this paragraph. Refer also to "Check Network Wiring" on the next page, before attaching the 4-position NET connector. Apply power after all connections have been made.

PROBLEM SOLVING

Troubleshooting

The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative.

NOTE: Operation is ultimately determined by the control system program; this must be considered when troubleshooting.

TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION

Device does not turn on (PWR LED is not lit).

Device does not function as expected.

Device is not receiving power from a Crestron power source.

Device is not receiving sufficient power.

Device is not configured correctly.

Incorrect programming in control system.

Use a Crestron power source. Verify connections.

Use the Crestron Power Calculator to help calculate how much power is needed for the system.

Verify rotary switch settings and device wiring.

Check control system logic or contact Crestron for assistance.

Check Network Wiring

Use the Right Wire

In order to ensure optimum performance over the full range of your installation topology, use Crestron Certified Wire only. Failure to do so may incur additional charges if support is required to identify performance deficiencies because of using improper wire.

Calculate Power

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 unpredicatable results or damage the equipment. Use the Crestron Power Calculator (www.crestron.com/calculators) to help calculate how much power is needed for the system.

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 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

L = Length of run (or chain) in feet

40,000

L <

R x P

Make sure the cable length value is less than the value calculated on the right side of the equation. For example, a Cresnet run using 18 AWG Crestron Certified Wire and drawing 20 Watts should not have a length of run more than 333 feet (101 meters). If Cresnet HP is used for the same run, its length could extend to 1250 feet (381 meters).

NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One twistsed pair is the +24V conductor and the GND conductor and the other twisted pair is the Y conductor and the Z conductor.

Strip and Tin Wire

When daisy chaining Cresnet units, strip the ends of the wires carefully to avoid nicking the conductors. Twist together the ends of the wires that share a pin on the network connector and tin the twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle. Insert the tinned connection into the Cresnet connector and tighten the retaining screw. Repeat the procedure for the other three conductors.

Add Hubs

Use of a Cresnet Hub/Repeater (e.g., CNXHUB) is advised whenever the number of Cresnet devices on a network exceeds 20 or when the combined total length of Cresnet cable exceeds 3000 feet (914 meters).

Where:

R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 mm ))

or 1.6 Ohms (Cresnet HP: 12 AWG (4 mm ))

P = Cresnet power usage of entire run (or chain)

Regulatory Compliance (Continued)

NOTE: This equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and if not installed in and used accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and receiver

• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected

• Consult the dealer or an experienced radio/TV technician for help
