System RAM RAM installed on your personal computer and used by the operating
system, as contrasted with onboard RAM, which is installed on the
PCI-MXI-2 or VXI/VME-MXI-2.
T
trigger Either TTL or ECL lines used for intermodule communication.
TTL Transistor-Transistor Logic
U
user window A region of PCI address space reserved by the PCI-MXI-2 for use via
the NI-VXI low-level function calls. MapVXIAddress() uses this
address space to allocate regions for use by the VXIpeek() and
VXIpoke() macros.
V
V volts
VDC volts direct current
VIC or VICtext 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 0 of a VXIbus mainframe
Controller or Slot 1 of a VMEbus chassis. This 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/VXIbus 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.
