National Instruments GPIB with National Instruments DriversManufacturer:
The National Instruments GPIB boards and drivers should be installed according to National Instruments instructions. spec communicates with the boards using only the device node /dev/gpib0. (On System V PC Platforms, where the GPIB driver is linked into the kernel, and the kernel is patched using the ibconf program, you should run ibconf directly on the driver file, so that each time you rebuild a kernel, you won't need to rerun ibconf. Thus, you might run ibconf /etc/conf/pack.d/ib2/Driver.o after the driver has been installed.) When you do configure /dev/gpib0 with the ibconf program, set the controller primary address to 0, the secondary address to none, board-is-system-controller mode to yes and disable-auto-serial-polling mode to yes. Other board configuration parameters are programmed by spec each time it is run, thus overriding any values you may set using the ibconf program. Those parameters are: timeout setting, EOS byte, terminate-read-on-EOS mode, type of compare on EOS, set-EOI-w/last-byte-of-write mode and UNIX signal. The special nodes that may be created for each individual device by the National Instruments installation program are not used at all. |
