CEN-RGBHV 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 your installation
topology, Crestron Certified Wire and only Crestron Certified Wire may be used.
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.
Add Hubs
For larger networks (i.e., greater than 28 network devices), it may become necessary
to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality throughout the
network. Also, for networks with lengthy cable runs it may be necessary to add a
Hub/Repeater after only 20 devices.
