Introduction
IEQ11 is IEEE488/GPIB adapter for PDP and VAX. To configure it 2 steps must be applied - compilation and loading of NI-PCI/GPIB PCI PassThrough device driver and confuguring CHARON.

NI-PCI/GPIB PCI PassThrough device driver
CHARON supports NI PCI/PCIe/GPIB boards in pass-through mode using a specific driver that can be built from sources located in "/opt/charon/drivers/ni_pci_gpib_ppt" directory. Upon loading the driver (".ko" loadable module) into OS kernel at runtime it creates "/dev/gpib<i>" device for each NI PCI/PCIe/GPIB board it finds.

Configuring CHARON
Once NI-PCI/GPIB PCI PassThrough device driver is compiled and loaded configure CHARON in the following way:
VAX configuration
load IEQ11 IEA
set IEA host_bus_location[0] = "/dev/gpib<N>"
set IEA host_bus_location[1] = "/dev/gpib<M>" |
...
load IEQ11 IEA
set IEA host_bus_location[0] = "/dev/gpib0"
set IEA host_bus_location[1] = "/dev/gpib1" |
PDP11 configuration
load IEQ11 IEA vector = 0270 priority = 6 set IEA host_bus_location[0] = "/dev/gpib<N>"
set IEA host_bus_location[1] = "/dev/gpib<M>" |
