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.
CEN-RGBHVHB Troubleshooting
TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION
Device does not
function.
Device is not
communicating with the
network.
Use Crestron Toolbox to poll
the network. Verify network
connection to the device.
Improper Net ID used. Verify that device ID matches
Net ID in the program.
Poor picture or
sound quality.
Cables improperly
connected.
Verify all cables are secure.
Check Network Wiring
Use the Right Wire
In order to ensure optimum performance over the full range of the 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.
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.
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
unpredictable results or damage to the equipment. Use the Crestron Power
Calculator to help calculate how much power is needed for the system
(
www.crestron.com/calculators).
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 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.
