Each VXI crate contains a Slot 0 (Resource Manager) module (Struck 8032) which has inbuilt a standard VME CPU board (CES RIO2 8062 - PowerPC based with LynxOS). This communicates with the MIDAS control GUI via ethernet and allows setup and monitoring of all VXI modules in the crate. A logic analyser facility is built-in which can monitor some VXI backplane lines.
Further about the Resource Manager

Each VXI crate contains a Readout Controller module (Struck STR 8080 - VRE) which contains a DSP. In addition to code to handle normal readout extensive diagnostic and test facilities are built-in. These include diagnostics to locate faults within the VXI crate and data generation features to aid system testing.

Using the Register Server the user can via the MIDAS GUI set and monitor all adjustable controls built into the VXI cards. Once the setup of the electronics is satisfactory the values of all parameters can be saved to disc. Complete electronics setups or just a selected portion can be quickly restored back into the electronics should this be necessary.
