Figure 2-3. Interrupt Jumper Settings
To change to another interrupt line, remove the jumper from its stored
position and place it on the new posts.
If you change the hardware interrupt line to something other than IRQ5,
make sure that you make a corresponding change to the software interrupt
setting as described in Chapter 3, Software Installation and Configuration.
Also, make sure that you record the new setting on the AT-GPIB Hardware
and Software Configuration Form in Appendix D, Customer
Communication .
