Non-Slot 0 Resource Manager Operation
The startup sequence for a GPIB-VXI/C configured for Non-Slot 0
Resource Manager operation is nearly identical to the Slot 0 Resource
Manager operation; however, the GPIB-VXI/C controls the Slot 0
resources remotely in Non-Slot 0 RM operation.
A VXIbus Slot 0 device must be in the system. It must be either a
Register-Based device that implements the MODID Register or a
Message-Based device that supports the Word Serial commands

Follow these steps to configure the GPIB-VXI/C for Non-Slot 0
Message-Based operation. Refer to Table 2-12.
1.
Disable the VXIbus Slot 0 functions.
2.
Set the model code of the GPIB-VXI/C to be configured for
Non-Slot 0 operation using the nonvolatile configuration mode.
3.
Set the logical address to a non-zero value with an appropriate Servant
area size using the nonvolatile configuration mode or by using DIP
switch SW1.
