Are there similar cables available in the market? Crestron recommends to use their own cables.



Thanks

You do not have to use Crestron cables in a Crestron system. Crestnet wires are 1 pair shielded/2 conductor and the shielded pair should be twisted and low capacitance. However, you can use CAT5 or CAT5e but you will have to double up your pairs for power and ground.


Crestron Video reqires up to 3 CAT5e and a Crestnet wires but it is often useful to run an extra CAT5e. Again you can use a bundled wire or you can pull them separately. Indeed you could use coax on a PVID if that is what you wanted and send the wire back down stream. You would not avail yourself of the compensation network available on the room control boxes for CAT5 but if you run is under 100 ft it should not matter.

When you say 3 CAT5e, are you referring to 3 runs of CAT%e (where each run includes 4 pairs), or are you referring to 3 pairs of CAT5e wire?

Crestnet is 24,Y,Z, and G. It is a 485 bus which means you have a balanced data connection ( Y and Z ) with a common ground. For this you can use a 1 pair twisted shielded for data and 2 conductor for power. You can also use CAT5 or CAT5e where one pair ( eg., orange ) is for Y and Z and the blue pair and Brown solid and the Green pair and Brown White are tied together for +24 and Ground.


Crestron Video uses CAT5e to carry audio and video over CAT5e. You need 3 separate CAT5e wires. One CAT5e for bidirectional audio, a second CAT5e for video send ( centralized video to local source ) and a third CAT5e for local video sent back to the centralized switcher to be distributed to other rooms ( Family Room DVD sent to MBR ). In this way any kind of signal ( composite, S-video, Component and digital audio ) can be sent in both directions. Composite video can be sent over Crestron 700ft, S-Video 700 ft and component 500ft.


You need 4 CAT5e cables; one for Crestnet, two for bidirectional audio, third for video send and a forth for video return. Composite video is carried on the blue pair, Y and C are carried on the blue and Orange pairs, and Y, Pb and Pr are carried on the blue, orange and green pairs. The brown pair is for digital audio.


Yes, you need 3 separate runs ( where each run includes 4 pairs ) and a Crestnet wire for Crestron Video.


If you include TPS touch panels you may wish to run, Crestnet, Cat5e and 2 2 pair shielded wires so you can use the built in microphone and speaker in the touch panel as an intercom.
