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.
NOTE: 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.

CAT5 Wiring (CH Versions Only)

Category 5 (CAT5) wiring is a twisted pair cable designed for Ethernet networks.
These networks operate at speeds of up to 100 Megabits per second (Mbps) using the
100baseT standard. Crestron takes advantage of this specification for a variety of
audio and video applications.
Crestron recommends using CresCAT, CresCAT-D, or CresCAT-Q wiring solutions.
The following chart shows the maximum recommended cable lengths for various
signal formats.

Reference Guide (Doc. 6137).

QM Network Wiring (QM Versions Only)

For the QuickMedia transport, use CRESCAT-QM cable.
The aggregate cable length from transmitter to receiver cannot have a delay skew of
more than 22 ns for a given signal path originating at a QM transmitter and
terminating at a QM receiver. The aggregate cable length must not exceed 328 feet.
When connecting multiple QM devices, the route between a QM origination point
(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints
(e.g., QM-MD7x2 or other QM switchers). Refer to the following diagram when
configuring a QM network.
