VME-SB2020/NI-VXI/Solaris Getting Started
slave
A functional part of a MXI/VME/VXIbus device that detects data transfer
cycles initiated by a VMEbus master and responds to the transfers when
the address specifies one of the device's registers.
slave-mode
A device is in slave mode it if is responding to a bus cycle.
operation
statically
A device whose logical address cannot be set through software; that is,
configured device
it is not dynamically configurable.
SYSFAIL
A VMEbus signal that is used by a device to indicate an internal failure.
A failed device asserts this line.
T
trigger
Either TTL or ECL lines used for intermodule communication.
TTL
Transistor-Transistor Logic
V
VDC
volts direct current
victext
Text-based VXI Interactive Control Program, a part of the NI-VXI bus
interface software package. Used to program VXI devices, and develop
and debug VXI application programs.
VME
Versa Module Eurocard or IEEE 1014
VMEbus System
A device configured for installation in Slot 1 of a VMEbus chassis. This
Controller
device is unique in the VMEbus system in that it performs the VMEbus
System Controller functions, including clock sourcing and arbitration for
data transfers across the backplane. Installing such a device into any other
slot can damage the device, the VMEbus backplane, or both.
VXIbus
VMEbus Extensions for Instrumentation
vxiinit
A program in the NI-VXI bus interface software package that
initializes the board interrupts, shared RAM, VXI register
configurations, and bus configurations. This program must be run at
least once after rebooting your machine to initialize the system.
