A VME/VMX - CAMAC Interface and Crate Controller

A VME/VMX bus interface has been designed and built to interface a VME-based data acquisition system to CAMAC. The interface communicates via a differential bus with a companion unit that functions as a CAMAC crate controller. The interface maps both VMiE and VMX address cycles into appropriate CAMAC cycles. Special diagnostic features have been incorporated in the design to allow quick fault detection and location.
