HS488
The NB-GPIB/TNT uses a high-speed
GPIB protocol (HS488). HS488, patented
by National Instruments, increases the
maximum data transfer rate of ANSI/IEEE
Standard 488.1-1987 up to 8 Mbytes/s.
HS488, a superset of the IEEE 488.1
protocol, attempts to conduct data transfers
with the new higher speed protocol.
