user-defined variables have been initializd.
The following paragraphs contain descriptions of the fields in the
Non-Volatile Configuration Information Display.
This field contains the VXI logical address of the 1260-00C. It
specifies the location of the registers in VXI A16 space. The
formula is as follows:
C000h + (40h * Logical Address)
If the Logical Address is set to 0, the 1260-00C will attempt to be
the VXI Resource Manager. If the Logical Address is set in the
range of 01 to FEh (1 through 254), the 1260-00C is set up to be a
Static Configuration (SC) Message-Based (or possibly
Register-Based) device. If the Logical Address is set to FFh (255),
the 1260-00C is set up to be a Dynamic Configuration (DC)
Message-Based (or possibly Register-Based) device. The factory
setting is Logical Address 0.
The 1260-00C can be set up either as a Message-Based or a
Register-Based VXI device. Normally, the 1260-00C should be a
Message-Based device. In Register-Based mode, the 1260-00C
can reside virtually transparently in the VXI system for use as a
debugging tool. It can still access the VXIbus directly as a bus
master, perform Word Serial operations and GPIB transactions,
and use Code Instruments. None of the functionality is removed.
The Resource Manager does not grant any Servants to a
Register-Based 1260-00C.
The Manufacturer ID is set at the factory and cannot be changed.
Manufacturer IDs are assigned by the VXI Consortium. The
Manufacturer ID for Racal-Dana is 4091.
The 1260-00C can be configured for either Slot 0 or Non-Slot 0
operation. According to the VXIbus specification, a device
configured to be in Slot 0 must have a Model Code between 000h
and 0FFh. A device configured to be in a slot other than Slot 0
must have a Model Code greater than 0FFh. The 1260-00C
Model Codes are assigned by Racal-Dana. This field is used only
to configure which one of the two Codes to use. The factory
setting is for Slot 0.
