Check Network Wiring

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.
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.
Use of a Cresnet Hub/Repeater (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).

CORRECTIVE ACTION
Use Crestron Toolbox to poll
the network. Verify network
connection to the device.
Pair the amplifier with a
PSPHD.
