The board ID should be set up according to the system slot into which the board is inserted, as shown in
the following table. The board ID also sets the board’s VME slave addresses, as shown, so take care to
avoid an address clash with other boards in the system.

Note:
Any change to the Board ID links will require the hardware registers to be ‘relearned’ if BIT is not to fail.
VMEbus Interface Configuration
Several operating features of the Universe II VME interface are set at power-up or reset by surface
mount jumper links. All of these, except local register access, may be overridden by software. The
default settings are:
O
PERATING
F
EATURE
S
ETTING
Register access slave image from vmebus
Enabled in A32 space at 0x8000 0000
Vme cr/csr slave image
Disabled
Pci slave image 0
Enabled in PCI memory space at 0xF000 0000 to 0xFFFF FFFF
Local register access
PCI I/O space
Auto-id scheme
Disabled
Changing the default power-up options requires surface-mount rework tools and would normally only be
done at the factory. Further details are available from technical support at Radstone.
