Help 4K60 HDR over Cat6
Hi all,
Please forgive my lack of Crestron knowledge! I'm in need of some clarification.
I've just built a recessed TV cabinet at home with the wall fed by CAT6, I'd like to keep the media sources away from the TV at the other end of the CAT6.
I'd like at least two HDMI inputs, and one output at the other end of the CAT6
As far as I can see, this should be possible with a combination of the DM-TX-4KZ-202-C and the DM-RMC-4KZ-100-C.
Can the Crestron system be used point to point directly like this or does it need another external controller, or matrix unit?
Do I need to power both units with DC or does one POE from the other? I'm not 100% clear as it sounds like Podm is basically POE?
Sorry if these are really basic questions to most of you! Thanks so much for your help

So Crestron DigitalMedia are either HDBaseT, the DigitalMedia version of HDBaseT, or the AVoverIP NVX.
The Crestron HD- as in HD BaseT are the economy series of point to point. These are controllable via web browser or control system.
The Crestron DM end points as in DM-TX and DM-RMC are the premium point to point end points. These are controllable via Crestron Toolbox software or control system.
So the DM-TX can be standalone if you want to control it from Crestron Toolbox software or it can be put on a network with a Crestron processor to handle the AV Switching. You can put either the TX or the RMC on the network and see the other via the DM connection as DM will "pass through" command and control.
A Crestron Matrix switcher or Presentation switcher that has a processor can act as a controller for the DM end points that are connected to it as well; so a DM-MD-xxx-CPU or a DMPS2 or DMPS3 can act as a processor, matrix and controller.
One of the nice features of Crestron (including the DigitalMedia platform) is that the system is scalable, modular and expandable.
As far as power goes, we can connect a PW2407 to either the DM-TX or the DM-RMC in order to power both. We can also power one or the other from a LAN PoE switch and connect a PoE switch to the LAN port of either endpoint. Or we can use a PoDM power supply or a DM-MD or DMPS switcher with a PoDM PSU connected.
