Vme System Controller (J1); Ip Bus Strobe (J11) - Motorola MVME162P2 Series Installation And Use Manual

VME System Controller (J1)

The MVME162P2 board is factory-configured in "automatic" system
controller mode with a jumper across J1 pins 2-3. In this configuration, the
MVME162P2 determines whether it is the system controller by its position
on the bus. If the board is located in the first slot from the left, it configures
itself as the system controller. When the board is operating as system
controller, the
If you want the MVME162P2 to function as system controller in all cases,
move the jumper to pins 1-2. If the MVME162P2 is not to be system
controller under any circumstances, remove the jumper from J1.

IP Bus Strobe (J11)

Some IP bus implementations make use of the Strobe∗ signal (pin AA19
on the Petra ASIC) as an input to the IP modules from the Petra IP2 sector.
Other IP interfaces require that the strobe be disconnected.
With a jumper installed between J11 pins 1-2, a programmable frequency
source is connected to the Strobe∗ signal on the IP bus (for details, refer to
the Petra/IP2 chip programming model in the Programmer's Reference
Guide).

On MVME162P2 boards without the optional VMEbus interface
(i.e., with no VMEchip2 ASIC), the jumper may be installed or
removed with no effect on normal operation.
