THEORY OF OPERATION
3.1 OPERATIONAL OVERVIEW
The VMIVME-2131 is designed for a variety of applications such as:
a.
Relay drivers.
b. Lamp drivers.
c. Solenoid drivers.
d. Hammer drivers.
e. Stepping motor drivers.
f. Triac drivers.
g. LED drivers.
h. High current, high voltage drivers.
i. Fiber-optic LED drivers.
The design of the VMIVME-2131 Board, as shown in the functional block
diagram in Figure 3.1-1, consists primarily of 4 sections which are:
a. Device addressing.
b. VMEbus foundation logic.
c. Built-in-Test logic.
d. Output drivers.
The board is designed using eight bi-directional 8-bit registers, a Control
and Status Register (CSR), high performance output drivers, typical VMEbus
foundation logic, and two device address jumper banks. The two jumper banks
provide the user with the capability and flexibility to map I/O registers and CSRs into
separate contiguous memory locations.
