2. Before Installation

Before installing the EPC-7, unpack and inspect it for shipping damage.

 DO NOT REMOVE ANY MODULES FROM THEIR ANTI-STATIC BAGS

UNLESS YOU ARE IN A STATIC

-FREE ENVIRONMENT. THE EPC-7

MODULES

, LIKE MOST OTHER ELECTRONIC DEVICES, ARE

SUSCEPTIBLE TO ESD DAMAGE. ESD DAMAGE IS NOT ALWAYS

IMMEDIATELY OBVIOUS

, IN THAT IT CAN CAUSE A PARTIAL

BREAKDOWN IN SEMICONDUCTOR DEVICES THAT MIGHT NOT

IMMEDIATELY RESULT IN A FAILURE

 THE EPC-7 CONTAINS A HARD DISK. PLEASE HANDLE IT WITH

CARE

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.
