With the CR1-RACK, EKF introduces a 19-inch rack for double size CompactPCI® boards (6U Eurocard). The CR1-RACK is a very low space consuming solution for horizontal mounting of two CPCI boards and has been designed for optimum air-flow conditions. The CR1-RACK is well suited for accommodating an all-in-one CPU board such as the CD2-BEBOP or CD3-JIVE, with an on-board mass storage unit and (optionally) a rear I/O transition module. Another CPCI slot is provided for an additional I/O board.
