Interface Module Crestron TPMC-CH-IMC
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.
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
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.
Recommended Maximum Cable Lengths for Audio/Video via CAT5
FORMAT MAXIMUM DISTANCE
Composite 750 feet
S-Video 750 feet
Component 500 feet
Audio 1000 feet (balanced)*
* The maximum distance for CAT5 audio is limited to approximately 15 feet
when connecting the AUDIO OUT port to a device with an unbalanced input.
If the AUDIO OUT port connects to a device with balanced inputs or no
device is connected, the maximum cable length for CAT5 audio is 1000 feet.
For more information, refer to the latest version of the Crestron CAT5
Wiring Reference Guide (Doc. 6137).
