The AORTA-R-V2 is a VME-slave that can be accessed by A24 or A32 VME-cycles (jumper selectable). The VME base address of the board can be set over the full 32-bits byte-address range in steps of 64K using 4 on-board rotary hex-switches.
Table 2 shows the mapping of the available registers and address locations relative to the base address, their function and their read/write capability.
