MODID Lines
Module/system identity lines.
Physical Address
The address assigned to a backplane slot during an access.
Power Monitor
A device that monitors backplane power and reports fault conditions.
P1
The top-most backplane connector for a given module slot in a vertical
mainframe. The left-most backplane connector for a given slot in a horizon-
tal mainframe.
P2
The bottom backplane connector for a given module slot in a vertical C-size
mainframe; or the middle backplane connector for a given module slot in a
vertical D-size mainframe such as the VX1500.
Query
A form of command that allows for inquiry to obtain status or data.
READY Indicator
A green LED indicator that lights when the power-on diagnostic routines
have been completed successfully. An internal failure or failure of +5 V
power will extinguish this indicator.
Register Based Device
A VXIbus device that supports VXI register maps, but not high level
VXIbus communication protocols; includes devices that are register-based
servant elements.
Requester
A functional module that resides on the same module as a Master or
Interrupt Handler and requests use of the DTB whenever its Master or
Interrupt Handler requires it.
Resource Manager
A VXIbus device that provides configuration management services such as
address map configuration, determining system hierarchy, allocating shared
system resources, performing system self test diagnostics, and initializing
system commanders.
Self Calibration
A routine that verifies the basic calibration of the instrument module circuits,
and adjusts this calibration to compensate for short- and long-term variables.
Self Test
A set of routines that determine if the instrument module circuits will
