SIMM Single In-line Memory Module
slave A functional part of a 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
SMB Sub Miniature Type B connector that features a snap coupling for fast
connection
System Controller a device configured for installation in Slot 0 of a VXIbus mainframe or
Slot 1 of a VMEbus chassis. This device is unique in the VXI/VMEbus
system in that it performs the VXI/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 VXI/VMEbus backplane, or both.
T
trigger Either TTL or ECL lines used for intermodule communication
TTL Transistor-Transistor Logic
U
user window A region of address space reserved by the VXI/VMEpc 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
VIC VXI Interactive Control Program, a part of the NI-VXI bus interface
software. Used to program VXI devices, and develop and debug VXI
application programs.
VISA Virtual Instrument Software Architecture. This is the general name given to
VISA and its associated architecture. The architecture consists of two main
VISA components: the VISA Resource Manager and the VISA Instrument
Control Resources.
