Digital QMT® Shade Motor for QMT5 Series, 4 Nm, Cresnet®
An ultra-quiet, ultra-reliable brushless motor for Crestron® roller shades, 18 inches (458 mm) and larger. Cresnet® communications provides a single-wire, low-voltage interface that allows for precise, programmable remote control, monitoring, and automation.
NOTE: The CSM-QMTDC-250-4-CN is only available as part of a Crestron® shade system and cannot be ordered on its own. To configure shades or order shading parts and accessories, please use the Crestron Design Tool for Crestron Shading Solutions or call 1-855-53-SHADE (1-855-537-4233) for support.
Featuring Digital Quiet Motor Technology™, the CSM-QMTDC-250-4-CN motor provides quiet yet robust operation for Crestron® roller shades 18 inches (458 mm) and larger.  Fully integrated electronics eliminate the need for bulky add-on interface modules, allowing for a clean, streamlined installation. The CSM-QMTDC-250-4-CN uses the dependable Cresnet® wired network for communication with a Crestron 3-Series Control System® or Crestron Pyng® system. Operating power is also supplied via the Cresnet connection, eliminating the need for a local power supply or AC outlet.
For a wireless shade motor alternative with infiNET EX® technology, see model CSM-QMTDC-250-4-EX.
The CSM-QMTDC-250-4-CN can integrate seamlessly into a Crestron control system or Crestron Pyng system, allowing it to be operated alone or as part of a group using keypads, wireless remotes, touch screens, and mobile devices. Operation can also be automated in combination with lighting and other equipment using scene presets, scheduling, daylighting, and occupancy sensing. Simple setup controls are included on the CSM-QMTDC-250-4-CN to facilitate testing and adjustment of shade limits by the installer.
Power is supplied to the CSM-QMTDC-250-4-CN via a dedicated power supply (model CSA-PWS40 )]) or 10-motor power supply (model CSA-PWS10S-HUB-ENET ). Power and communications are distributed together over a single Cresnet wire, allowing all supporting equipment to be consolidated at a central location.
Digital Quiet Motor Technology™
Crestron Digital QMT® shade motors feature ultra quiet operation with the ability to position each shade precisely and monitor its movement remotely. A high-torque, long-life brushless motor design achieves smooth starts and stops with exceptional reliability backed by a limited lifetime warranty. Patented automatic torque calibration technology detects and reacts to obstructions in the shade path to prevent damage to the motor or shade material.
The Cresnet network offers a simple wiring solution for shading systems composed of one or more Crestron Digital QMT motors. A single homerun Cresnet wire carries bidirectional control signals and 24 VDC power to each motor. Sophisticated management of every motor is enabled using Crestron 10-motor power supplies featuring built-in Cresnet distribution, diagnostics, and Ethernet connectivity (model CSA-PWS10S-HUB-ENET ).
