Configuring the EPC-7 Jumpers
Slot 0 and System Controller Configuration
Before installing the EPC-7 in a VXIbus chassis, a decision must be made whether
the EPC-7 is to be the slot 0 controller and the VMEbus system controller. Every
VXIbus system needs a module that performs the VMEbus system controller
functions (generation of the 16 MHz SYSCLK signal, arbitration of the bus, detection
of bus timeout conditions, and initiation of the interrupt-acknowledge daisy chain),
and the VXIbus slot-0 functions (generation of the 10 MHz ECL CLK10 signals and
control of the MODID module identification function).
Typically, the same device is the slot-0 controller and VMEbus system controller.
The EPC-7 is shipped configured as a VXI slot 0 controller. If this is the intended
use of the EPC-7 (which will usually be the case), skip the rest of this section.
The EPC-7 has nine jumper positions appearing through its rear panel between the
P1 and P2 connectors. See Figure 1 below.
