IEEE
Acronym for the Institute of Electrical and Electronics
Engineers.
RS-232
A serial, full-duplex, asynchronous communication port that
follows ANSI/EIA/T IA-562-1989[1], ANSI/EIA/
TIA-574-1990[2], and CCITT V.24-1989[3] standards.
Serial Poll
A device (such as an oscilloscope) on the GPIB bus can request
service from the GPIB Controller by asserting the GPIB SRQ
line (a Hardware line tha t is only present on the GPIB
communications bus). A device on the USB bus can request
service from the host by sending an SRQ packet on the
Interrupt-IN endpoint. When a controller or a USB host
acknowledges the SRQ, it “serial polls” each open device on the
bus to determine which device on the bus requested service. Any
device requesting service returns a status byte with bit 6 set and
then unasserts the SRQ line (GPIB only). Devices not requiring
service return a status byte with bit 6 cleared.
USB
An acronym for Universal Seri al Bus.
USBTMC
An acronym for USB Test and Measurement Class.
USB488
The USBTMC subclass specification that implements an
IEEE488-like interface over USB.
