The Dawn VME DEV-7713 is a 6U VME64x tabletop development chassis purpose-built for VMEbus system prototyping, integration, and evaluation. Featuring a 9-slot backplane with optimized signal integrity and automatic IACK/BG daisy chaining, it delivers a stable platform for laboratory-based hardware and software development. The integrated 400W ATX power supply supports distributed loads across all slots, while eight 12VDC fans maintain controlled bottom-to-top laminar airflow. Housed in a durable H5052 aluminum enclosure with powder-coat black finish, the DEV-7713 accommodates standard IEEE1101.10 cards and includes a transition module cage for 6U × 80mm IEEE1101.11 rear plug-in capability.
