Installing and Configuring the E1459A
Setting the Logical Address
Each module within the VXIbus mainframe must be set to a unique logical
address. The setting is controlled by an 8 pin dip switch. This allows for values
from 0 to 255. The factory setting of this switch is decimal 144. No two modules
in the same mainframe can have the same logical address. The location is shown
in Figure 5.
Setting the Interrupt Priority
At power on, after a SYSRESET, or after resetting the module via the control
register, all masks will be cleared, interrupts will be disabled, and internal
triggering will be enabled. With interrupts enabled, an interrupt will be
generated whenever an edge occurs on a channel that has been enabled
properly.
The interrupt priority jumper selects which priority level will be asserted. As
shipped from the factory, the interrupt priority jumper should be in position 1. In
most applications this should not be changed. When set to level X interrupts are
disabled. The interrupt priority jumpers are identified on the sheet metal shield. A
hole has been cut into the shield for access to the jumpers. Interrupts can also be
disabled using the Control Register.
The jumper locations are shown in Figure 5. To change the setting, move the
jumper or jumpers to the desired setting. If the card uses two 2-pin jumpers
versus a single 4 pin jumper, the jumpers must all be placed in the same row for
proper operation.

Consult your mainframe manual to be sure that backplane
jumpers are configured correctly. If you are using the Keysight
E1401B Mainframe these jumpers are automatically set when the
card is installed.
