The Ziatech ZT-4804B is a CompactPCI Rear Panel I/O (RPIO) transition board, designed to provide rear-panel access to I/O interfaces for a System Master CPU board (such as the Ziatech/Performance Technologies ZT 5550 series) in a CompactPCI (cPCI) chassis. It mounts in the rear slot of a CompactPCI backplane, opposite the front-mounted CPU board, routing signals such as Ethernet, serial ports, and other I/O to the rear of the chassis — a common design pattern in telecom-grade and industrial CompactPCI systems where front-panel access is impractical due to airflow, cabling density, or rack design. It is part of the same RPIO family as the related ZT 4805 (used for Peripheral Master CPU boards) and ZT 4807/4807A modules.
