CAT5 Wiring (CH-L 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-L 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.

QM-MD7x2 QM-MD7x2
The TPMC-15/17-QM-L is not a switcher, but a transmitter/endpoint. Therefore,
even when designated as the endpoint from two midpoint switchers, the QM output
of the TPMC-15/17-QM-L can become another transmitter sending RGB video at the
touchpanel's native resolution and aspect ratio.

QuickMedia Transport System

Using a proprietary signal routing solution, signals such as composite video, S-video,
RGBHV, audios, and microphone, are all transported using a single cable solution
called QuickMedia (QM).
