Chapter 1
INTRODUCTION
1.1 INTRODUCTION
The XVME-530 Analog Output Module (hereafter referred to as AOUT) is a powerful
D/A module which can generate eight 12-bit resolution analog signals. Output can be
either voltage
or current. The following output voltage ranges are jumper-selectable:
0-5V,
0 to lOV, +2.5V, +5V, +lOV. The jumper-selectable current range is 4-20 mA.
The eight outputchannels areopticallyisolated (300V) from the digital logic.
The gain and offset errors are both adjustable to zero, and the maximum overall error
is
0.5 LSB.
1.2
HOW THIS MANUAL IS ORGANIZED
This chapter provides a functional overview of the AOUT and presents the features of
XYCOM's Standard
1/0 Architecture. Operational aspects of the AOUT are then
explained in the following fashion:
Chapter 2 - Installation -- Presents information required to position the jumpers
and switches on the AOUT, and then install
it on a VMEbus chassis.
Chapter 3 - Programming -- Presents information required to program the
AOUT and output analog signals.
The appendices at the rear of this manual provide information on XYCOM's Standard
1/0 Architecture, VMEbus connector/pin description, module schematics, and a quick
reference guide
to the AOUT's jumpers and registers.
1.3 OVERVIEW
Figure 1-1 shows an operational block diagram of the VMEbus compatible Analog
Output module (AOUT).

Figure 1-1. Block Diagram of the Analog Output Module
As can be seen from Figure 1-1, the AOUT consists of the Non-Intelligent Kernel
which
is standard for XYCOM's non-intelligent VMEbus modules, and application
circuitry specific
to the AOU'T.
1.3.1 XYCOM Non-Intel-ent Kernel
The Non-Intelligent Kernel is basically the interface to the VMEbus. It provides all
the necessary circuitry to receive and generate the signals required by the VMEbus
specification for
a 16-bit slave. By simply adding the application circuitry (in this
1-2

XVME-530 Manual
October, 1984
case D/A circuitry), a VMEbus module is complete. The Non-Intelligent Kernel has the
following features:
0 Control and Address Buffers
0 Address Decode circuitry
0 Control/Status Register
0 Module identification information
0 Pass and Fail LED indicators
The XYCOM Non-Intelligent Kernel is described in further detail in Appendix A.
1.3.2 Application Circuitry
As Figure 1-1 shows, the application circuitry consists primarily of the following:
0
0
0
0
0
8 D/A converters which perform 12-bit resolution D/A conversions
Data latch to store the digital data
to be converted to analog
Channel latch
to select the output channel over which the data will be
output
Optical isolator
to isolate between the digital and analog circutry
Timing controller to transfer digital information across the optical isola-
tion boundary to the D/Afs
1.4 FEATURES OF XYCOM'S STANDARD I/O ARCHITECTURE
The AOUT and all XYCOM 1/0 modules conform to the unique XYCOM VMEbus
Standard I/O Architecture. This architecture
is intended to make the programming of
XYCOM VMEbus
1/0 modules simple and consistent. The following features apply to
the operation
of the AOUT.
0
Module Address Space - The AOUT and all VMEbus modules are controlled
by writing
to addresses within the 64K Short 1/0 Address space. A VMEbus
module can be jumpered
to occupy any of the 64 available 1K blocks.
This block, known
as the 1/0 Interface Block, contains all of the module's
programming registers, and ID data. Within the 1/0 Interface Block, the
offsets are standardized
so that the user may expect to find the same
registers and data
at the same offsets across the entire XYCOM VMEbus
line.
Module Identification - The AOUT has I.D. information which provides its
name, model number, manufacturer and revision level at a location that is
consistent with other XYCOM 1/0 modules.
0 Status/Control Register - This re ister is always located at address
Base+81H, and the lower four bits
7 two Test Status bits, and a red and
green LED bit) are standard from module to module.
0
A detailed description of XYCOM 1/0 Architecture is presented in Appendix A at the
rear
of this manual.

Overall error is specified with gain and offset trimmed and is defined as
the deviation from a straight line passing through the end points of the
range. It
is expressed in terms of bits and in terms of the deviation as a
percent of the full scale range (Le., - +.5 LSB is - +0.0122% FSR of a -lOV
to +~OV range).
Conversion time is defined as the time required to transfer 12 bits of
data across the optically-coupled interface. It is measured from the
time the
low byte is written to when the analog output first starts to
change.

The AOUT has been constructed in accordance with XYCOM's Standard 1/0 Archi-
tecture
(see Appendix A for a detailed description). As such, it can occupy any one of
64 1K blocks of memory within the 64K VMEbus Short 1/0 Address Space. The
particular
1K block it shall reside in is selected by configuring the AOUT's "Base
Address'! equal to the beginning address
of that block. The Base Address is selected by
configuring 'switches 1-6
of the Address Switches (see Figure 2-21, as shown in Table
2-2.

2.4.4 BGxIN/BGxOUT and IACKIN/IACKOUT Daisy Chains
The Data Bus Arbitration signals BGxIN and BGxOUT (where lfxllcan be a number 0-3
to represent the three levels of arbitration) are not used by the AOUT, and are
hardwired together on the module
to allow the BGxIN/BGxOUT Daisy Chain to pass
through the backplane slot occupied by the AOUT. In each slot of the VMEbus
backplane, there are four
sets of jumpers shorting the signal BGxIN to BGxOUT (x=G
thru 3). Since these signals are already hardwired on the AOUT, it is not necessary to
insert these VMEbus jumpers on the slot occupied by the AOUT.
In addition, IACKIN/IACKOUT are hardwired together on the AOUT module.

2.4.5 Output Jumpering
~~~
Jumpers
(all other output jumpers should be removed)
The AOUT’s 8 outputs can each be individually configured in one of 6 different modes
by jumpering the operational amplifier buffer on the output
of each channel into
different coniigurations. Eacn configuration
is selected by placing jumpers across
certain points labeled
A, B, C, D, E, F, H, J, K, and L, on the AOUT circuit board.
The diagram format below will be used
to represent the jumper banks J5-Jl2. The
jumper configurations for each analog output option are listed in Table
2-5.

2.6.1 Installation Procedure
CAUTION
Do not attempt to install or remove any boards
before turning off the power
to the bus and all
related external power supplies.
Prior to installing a module, determine and verify
all relevant jumper configurations and all connec-
tions to external devices or power supplies. (Please
check the jumper configuration with the diagram
and lists in the manual.)
To install a board in the cardcage, perform the following steps:
1)
Make certain that the particular cardcage slot you are going to use is clear
and accessible.
2)
Center the board on the plastic guides so that the solder side is facing to
the left and the component side is facing to the right (refer to Figure 2-4).
Push the card slowly toward the rear of the chassis until the connectors
engage (the board should slide freely in the plastic guides).
Apply straight-forward pressure
to the two handles on the outer edge of
the board until the connectors are fully engaged and properly seated.
3)
4)
NOTE
It should not be necessary to use excess pressure or
force to engage the connectors. If the board does
not properly connect with the backplane, remove
the module and inspect all connectors and guide
slots for possible damage or obstructions.
5) Once the board is properly seated, it should be secured by tightening the
two machine screws
at the extreme top and bottom of the board.
