High-performance, single-cable wiring solution for DigitalMedia systems.
Crestron DM-CBL-NP cable provides a high-performance, single-cable wiring solution for DigitalMedia (DM) systems. Within a single jacket, DM-CBL-NP contains one high-bandwidth/low-crosstalk shielded 4-twisted pair (STP) cable, one CAT5e unshielded 4-twisted pair (UTP) cable, and one DMNet cable.
The STP "Video Data" cable, which connects to the 'D' port of a DigitalMedia device, is of a specialized construction designed to allow the longest possible cable lengths[1] for transporting high-definition digital video and audio. The Cat5e "Data Management" cable, which connects to the 'M' port, carries high-speed Ethernet and other data, plus 5V DC power. Finally, the DMNet cable carries additional proprietary control signals and 24V DC power.
Wiring a DigitalMedia system using DM-CBL-NP is simple, requiring just one cable to be run to each DM receiver (i.e. Room Controller) and transmitter location[1]. Foot markers are printed on the outer jacket making it easy to determine the exact length of each cable run when commissioning the installed system.
Termination of a DM cable is accomplished using one standard RJ45 (not provided) for 'M', one detachable terminal block (provided with each DM device) for DMNet, and one Crestron DM-CONN shielded RJ45 (sold separately) for 'D'. The DM-CONN connector enables fast and reliable termination of the shielded twisted-pair cable without requiring any special tools.
For plenum applications, use DM-CBL-P.
