L B U S Interrupt Handler Setting; 0 6 4 To Vxlvus Mainframe Installation - Racal Instruments 7064 Instruction Manual

For dynamic configuration, set the address switch to 255.
The 7064 Breadboard Module is shipped with the address set for
dynamic configuration. Refer to the Resource Manager's manual for
details about its addressing methods.
2.4 V X I B U S INTERRUPT HANDLER SETTING
One programmable interrupt line is provided on the 7064 module. This line is assigned by
using the assign interrupter line word serial protocol command (See Page 182 of Section E,
Revision 1.4 of the VXlbus Specifications). The Int_ID is set to 1.
2.5 7 0 6 4 TO VXIBUS MAINFRAME INSTALLATION
The 7064 module is ready for operation when shipped. The address switch is set to 255 to
allow for dynamic configuration by the VXI Slot 0 Resource Manager. See Section 2.3 if
static configuration (any switch setting other than 255) is preferred.
To install the 7064 in a C-size VXI chassis, use the following instructions:
1. E n s u r e power is OFF.
Configure the interrupt daisy chain on the backplane to bypass empty slots,
per VXlbus specifications.
3. R e m o v e the front cover of the VXI chassis, and slide the 7064 into the
appropriate slot with the LED's towards the top (or to the left when using a
horizontal chassis).
To ensure reliable VXlbus communications when using 7064 modules without a VXlbus
communications interface (i.e., 7064-6, 7064-7, and 7064-25 series), the user must note the
following. The VME Specification requires that the Interrupt Acknowledge (IACK) and
BUSGRANT (BG) signal lines be daisy-chained from slot-to-slot across the backplane. This
means that for each slot the BUSGRANT and IACK signals are input on Row A of the P1
2-2
NOTE
Logical address 0 is not allowed.
