logical address
An 8-bit number that uniquely identifies each VXIbus device in a system.
It defines the A16 register address of a device, and indicates Commander
and Servant relationships.

master
A functional part of a MXI/VME/VXIbus device that initiates data
transfers on the backplane. A transfer can be either a read or a write.
master-mode
A device is in master mode if it is performing a bus cycle which it
operation
initiated.
Message-Based
An intelligent device that implements the defined VXIbus registers and
device
communication protocols. These devices are able to use Word Serial
Protocol to communicate with one another through communication
registers.
modstat
A utility that checks the status of the loaded drivers. It displays the
module ID of the driver, the name of the device, and additional
information about the module.
MTBF
Mean Time Between Failure
MXIbus
Multisystem eXtension Interface Bus; a high-performance communication
link that interconnects devices using round, flexible cables.
MXIbus System
A functional module that has arbiter, daisy-chain driver, and MXIbus
Controller
cycle timeout responsibility. Always the first device in the MXIbus
daisy-chain.
