INTRODUCTION
1.1 FEATURES
The VMIVME-2131 is capable of delivering 64 channels of high current
output. These outputs can be current sourcing or current sinking. The VMIVME-
2131 is designed with a breakdown voltage of 35 V minimum. A unique feature of
the VMIVME-2131 Board is the Built-in-Test (BIT) logic, which allows the user, under
software control, to verify the operation of each channel.
A brief overview of the VMIVME-2131's features includes:
a. 64 bits of high current outputs.
b. Outputs may be current sourcing/High-Z or current source/sinks.
c. Output transient protected.
d. High-breakdown voltage (35 V minimum).
e. Tri-state outputs.
f. Built-in-Test logic for fault isolation.
g. High reliability DIN type output connectors.
h. 8-, 16-, or 32-bit transfers.
i. Double Eurocard form factor.
j. ±3.5 A peak output current (100 msec, 10 percent duty cycle).
k. 500 mA continuous current (fan cooled).
l. Thermal shutdown protection.
m. Front panel software controlled Failed LED for Built-in-Test.
n. Separate user configurable address jumpers for the Control and Status
Register (CSR) and the Data Registers allow for contiguous data
addressing when more than one I/O board is used in a VMEbus system.
1.2 FUNCTIONAL DESCRIPTION
The VMIVME-2131 is a member of VMIC's MEGAMODULE™ family. It is
designed with common programming features such that subsystems may be
configured with contiguous I/O addresses to conserve memory. Each of these
boards (VMIVME-1110, VMIVME-2130, VMIVME-2131, VMIVME-2120, and
VMIVME-2510) is designed with two sets of board address switches or jumpers to
provide an efficient memory address map for CSR and I/O addresses. CSR

500-012131-000
addresses may be set such that all CSRs among a variety of boards in the system
may be mapped into contiguous memory locations separate from the I/O data
addresses.
The MEGAMODULE™ product line is designed to support 8-, 16-, and 32-bit
data transfers and also features a front panel Fail LED that is illuminated at power-
up or after a system reset and may be extinguished under program control upon
successful completion of board level diagnostics. Specific hardware has been
designed into the VMIVME-2131 to support the Built-in-Test functions. The
VMIVME-2131 supports both off-line and on-line fault detection and isolation.

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.

3.2 DEVICE ADDRESSING
The VMIVME-2131 is designed to support data transfers in supervisory or
nonprivileged short I/O memory space. Jumpers are provided, as shown in Figure
3.2-1 (Address Selection Block Diagram), to allow user selection of either I/O access
type. These jumpers are called AM2. There is one jumper for the Data Registers and
one jumper for the CSR. The VMIVME-2131 is factory configured (jumpers AM2 not
installed) to respond to short supervisory I/O access.
10
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

The VMIVME-2131 is designed with two sets of board select jumpers and
decode logic as shown in Figure 3.2-1 to provide an efficient memory address map
for the CSR and I/O addresses. This feature allows the user to map CSR and I/O
addresses into separate contiguous memory locations when configuring subsystems
that require more than one board.
11
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

3.3 VMEbus FOUNDATION LOGIC
Typical VMEbus drivers, receivers, and control logic are shown in Figures
3.2-1, 3.3-1, and 3.3-2. The detailed logic design is shown on the schematic in
Appendix A.
3.4 DATA TRANSFERS
Data transfer transceivers are shown in Figure 3.4-1. The data
transceivers are designed to support write and read operations on 8-, 16-, and 32-bit
boundaries. Thus, the 64 current source/sink outputs are addressable as two 32-bit
longwords, four 16-bit words, or as eight 8-bit bytes.

3.5 REGISTER CONTROL LOGIC
The register control logic for the VMIVME-2131 Board is designed to
support write and read operations to and from the eight 8-bit bi-directional dual-port
latches and write transfers to a CSR that controls the test mode and front panel
LED. The control logic provides the capability to read or write 8, 16, or 32 bits of
data. This control logic is implemented in PALs as shown on the schematic in
Appendix A.
3.6 CONTROL AND STATUS REGISTER (CSR)
The CSR is a write-only register that controls the Test Mode (TM) bit and
the front panel Fail LED as shown in Figure 3.6-1. The TM bit disables the output
drivers to perform Built-in-Test functions. Both bits of the CSR are initialized active
upon system reset or power-up such that the driver outputs are disabled and the
front panel LED is illuminated. A jumper H1 is configured such that when writing a
logic "one" to bits 6 and 7 of the CSR, the LED is illuminated and the output drivers
are off-line.
14
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

3.7 BUILT-IN-TEST
The Built-in-Test feature of the VMIVME-2131 is enabled by asserting
(setting to a logical "one") the test mode bit in the CSR. As an aid to programming
the VMIVME-2131, a jumper (H1) is available to the user. This jumper can be used
to invert the input data to the CSR of the VMIVME-2131. It is used to permit existing
software to control the VMIVME-2131. If the program used writes "zeros" to the
CSR this jumper can be setup to invert this data (since the VMIVME-2131 uses
"ones" in the CSR). This way the H1 jumper can let the user run existing software
without modifications.
While in Test Mode, data may be written to any Output Data Register and
read back on a following read operation. This way the data written can be compared
to the data read and any action necessary can be initiated. While in Test Mode,
writing to an output device will have no effect on the field equipment, because the
output drivers are disabled during Test Mode operations.
The data loopback circuitry can be used even if TEST MODE is not active.
Thus, the Built-in-Test feature of this product provides the user with the capability of
performing real-time loopback testing with the output drivers connected to the field
15

equipment.
A front panel Fail LED is provided for quick fault isolation to the board
level. The Fail LED is illuminated at power-up or system reset and is extinguished
under software control by the user upon successful execution of a user-defined
diagnostic program. The board is initialized in the Test Mode at power-up or upon
system reset.
3.8 OCTAL REGISTERS AND OUTPUT DRIVERS
A block diagram of the eight 8-bit I/O registers is shown in Figures 3.8-1
and 3.8-2. The Output Data Registers were selected as the primary building block
of this design, because they have a unique feature that allows "read-back" of their
input data, which is used by the Built-in-Test functions. In Test Mode, the Data
Register outputs are tri-stated and the data read-back path is internal to the device.
Whereas, during normal operation the data read-back path includes the output pins
on the Output Data Register. Thus, during Test Mode all of the board's circuitry is
tested, except for the output drivers.

Due to the large output currents possible, each driver pair has a separate pin for
their source voltage and ground. This voltage is independent of the TTL control
voltage driving the output devices. Its maximum value is determined by the output
devices (UDN-2935ZH), which is 35 V. A detailed description of the output drivers is
given in the product specification, Document Number 800-012131-000.

CAUTION
THE USER SHOULD USE THE CABLE GROUND LINES FOR THE EXTERNAL POWER SUPPLY
RETURNS. THIS IS REQUIRED TO PREVENT EXCESSIVE CURRENT FROM FLOWING INTO
THE VMEbus BACKPLANE. ALSO, THE USER SHOULD REMOVE POWER BEFORE THE
CABLES ARE CONNECTED OR DISCONNECTED (FROM THE BOARD). THIS WILL PREVENT
EXCESSIVE CURRENTS FROM DAMAGING THE P3/P4 CONNECTOR PINS.
