Installation / Setup
The installation of the DRMM4 involves securing modules using the supplied #4-40 x 1/2″ PAN PHL screws at the two corners of each module. Modules are installed through one of the four openings in the front panel, with the handle toward the right-hand side. DC power cable connections and any module-to-module interconnections should be made before mounting the system into the rack. Proper polarity of cable connectors must be observed. Adequate ventilation is crucial, and units should be spaced apart by at least one panel height to prevent excessive heat, which can degrade system performance.
Operation
The DRMM4 is a 1RU rack mount carriage designed to accommodate up to four digital component series modules. It includes a built-in power supply with a universal input voltage switching capability and comes with an attached 115 VAC line cord. The power supply provides four separate DC output cables with polarized 3-circuit connectors. Modules are installed through the front panel openings of the DRMM4 and should be secured using #4-40 x 1/2″ screws at the two rear corners. Proper ventilation is important, and units should be spaced apart to ensure adequate airflow. DC power cable connections and any module-to-module interconnections should be made before mounting the DRMM4 system into the rack, ensuring proper polarity of cable connectors.
