System Controller Select Header (J1)
The MVME162LX is factory-configured as a VMEbus system
controller by a jumper across J1 pins 1 and 2. If you select the
ÔÔautomaticÕÕ system controller function by moving the jumper to J1
pins 2 and 3, the MVME162LX determines whether it is the system
controller by its position on the bus. If the board is in the first slot
from the left, it configures itself as the system controller. If the
MVME162LX is not to be system controller under any
circumstances, remove the jumper from J1. When the board is
functioning as system controller, the
