Chapter 2 - Overview
Introduction
The GX5280 Series are high performance, cost-effective 3U PXI dynamic digital I/O boards with 32 TTL I/O
channels and 32 LVDS I/O channels. The GX5280 Series offers an industry leading 512MB of on-board memory
and allows test rates up to 200 MHz (GX5283 Only). The single board design supports both master and slave
functionality without the use of add-on modules. Channels direction can be programmed on a per byte basis, i.e.
Group 0 (channels 0 -7) can be set as output while Group 1 (channels 8 -15) can be set to be input etc. Output
channels data is present on both LVDS and TTL Standard level I/O connectors. If the specified group is in input
mode, the user can select (software) which input interface to activate, i.e. LVDS or level (one of 3.3. 1.8, 1.5, 2.5).
The GX5280 Series utilize the PXI Local Bus to distribute signals across a domain.
All GX5280 cards offer programmable I/O width - trading vector width for vector depth. The GX5283 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 128M steps, 256M steps, 512M steps, 1G steps, 2G steps and 4G steps. The GX5282 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 64M steps 128M steps, 256M steps, 512M steps, 1G steps and 2G steps. The GX5281 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 32M steps 64M steps, 128M steps, 256M steps, 512M steps and 1G steps.
Marvin Test Solutions’ DIO is a family of high-speed, programmable, dynamic Digital Input and Output (I/O)
boards. These boards perform high-speed automated functional testing, device testing, simulation and data
acquisition. The DIO family provides real-time digital pattern capture and generation with 32 channels per card and
up to 16 cards or 512 channels.
The DIO family uses common software development tools to develop test vector files. The test vector files contain
digital patterns sent to or received from the Unit Under Test (UUT) and specific pre-defined setting for each board
in the setting.
Using DIOEasy or DIO driver functions, the development of vector files can be done without using the actual
hardware. Vector file verification requires the DIO be installed and properly configured.
Marvin Test Solutions bundles DIOEasy with all DIO products. DIOEasy, Marvin Test Solutions’ vector
development and analysis software, allows manual control of the DIO hardware using the built-in DIO Virtual
Instrument Panel. The DIO driver permits control of the DIO family from common software development tools such
as Marvin Test Solutions’ ATEasy, Microsoft Visual Basic, Microsoft Visual C++, Borland C++, Borland Delphi
and more.
DIOEasy, a Windows application used to develop digital vectors and does not require any programming experience
or knowledge to operate.
Computer Bus Interface
The DIO Driver accesses Master, Slave and carrier boards through the computer’s bus (see Figure 2-1). The driver
can accommodate up to 16 masters (from either family) and each master can have up to 7 DIO slave boards. ISA
based DIOs and carrier boards have switches to set their base address to identify by the driver where PCI and PXI
boards are using the physical slot number they are installed in to identify by the driver. PXI and PCI boards Master
and Slave numbers are set through selector switches located on the front.

4GX5280 User Guide
DIO Domains
A DIO domain has one Master DIO board and up to 15 DIO Slave boards. A DIO domain comprise of Master, its
Slaves, Carriers and related modules. Figure 2-1shows two domains from two different families on a PC bus.
Figure 2-1: Two Different DIO Domains on One PC Bus
Domains are internally synchronized and controlled via the PXI local bus. To synchronize a domain with a UUT,
you need to synchronize the Master board’s Timing signals using the Master’s Timing connector.
A full domain containing sixteen DIO boards provides up to 512 UUT I/O channels (512 channels wide). Because
the driver supports 16 masters, up to 16 domains of mixed types can, in principle, be supported in a PXI system. The
number of master/slaves depends on the number of available free PXI slots in your system.

GX5280 Architecture and Capabilities
The following are key GX5280 characteristics and architecture:
The GX5280 is a Plug and Play (PnP) board. The operating system (Windows 9x, Me, Windows 2000 or XP)
automatically identify and arbitrate resource requirements as well as notify the user that a new board was found
and automatically install the driver for it.
DIO domain operates independently of the host computer when in RUN mode.
Each GX5280 DIO board supports a maximum clock frequency of up to 200MHz (GX5283 Only) per channel
for all channels.
A GX5280 (Master) board controls the timing of its domain and can be synchronized to a UUT.
Any GX5280 board can be transforms to be Master or Slave depends on the on-board switch settings (can only
be done when the system is shutdown)
Multiple Master boards are used to synchronize mutually asynchronous UUT elements.
Each GX5280 Slave board adds 32 UUT channels. Up to 15 Slave boards can be added to make a total of 512
channel domain.
Programmable channel’s output enabled or disabled. Each channel can be enabled or disabled at any time
through software control. Disabled channels in output mode are in Tri-State. This is useful for connecting to a
user bus
Each Master has a 16-bit external event bus. This bus is used for triggering and synchronization with external
events.
Multiple trigger sources are available: Programmed PXI Trigger line, Star Trigger, External Trigger, Internal
trigger (software) or event driven trigger (generated by external events). All triggers sources can work in
tandem.
Event driven trigger can be generated by external events on the Timing connector External Event lines. Event
and Mask registers are used to determine both the triggering event and the masking bits to be ignored. These use
the D Event and D Mask registers and T Event and T Mask registers.
External triggering can be initiated on sequential or concurrent events by using both D and T event registers to
define events.
Multiple pause sources are available: Programmed PXI Trigger line, External Pause, Internal pause (software)
or event driven pause (generated by external events). All pause sources can work in tandem.
The test sequence (vector) can be paused on external events unconditionally or conditionally. P Event and P
Mask registers hold the condition and bits that generate a conditional pause.
An X Register is used to emulate an External Event condition under program control for purposes of test
program verification. The register is loaded through the computer bus.
DIO domain can be set to have internal or external clock, in order to synchronize with the user UUT.
DIO domain clock source (internal or external), active when outputting data, can be programmatically delayed
by 0-24 nSec (increments of 4nSec).
DIO domain Strobe source (internal or external), active when inputting data, can be programmatically delayed
by 0-24 nSec (increments of 4nSec).
All GX5280 Firmware can be upgraded through the DIO In-System- Programming (ISP).
Direction can be programmed on a per byte basis, i.e. Group 0 (channels 0 -7) can be set as output while Group
1 (channels 8 -15) can be set to be input etc.

immediately. Please refer to the warranty information at the beginning of the manual.
4. Return the board to its anti-static bag until ready for installation and setup.
System Requirements
All GX5280 instrument boards are designed for use with a 3U or 6U cPCI or PXI compatible chassis. The software
is compatible with any computer system running Windows 98, Windows Me, Windows 2000, Windows XP,
Windows VISTA (32 bit) operating systems.
Each board requires one unoccupied 3U PXI bus slot.
Installation of the GTDIO Software
Before installing the board it is recommended to install the software as described in this section:
1. Insert the Marvin Test Solutions CD-ROM and locate the GTDIO.EXE setup program. If you computer’s
Auto Run is configured, when inserting the CD a browser will show several options, select the Marvin Test
Solutions Files option, then locate the setup file. If Auto Run is not configured you can open the Windows
explorer and locate the setup files (usually located under \Files\Setup folder). You can also download the
file from Marvin Test Solutions web site (www.MarvinTest.com).
2. Run the setup and follow the instruction on the Setup screen to install the software.
Note: When installing under Windows 2000/XP/VISTA, you may be required to restart the setup after
logging-in as a user with an Administrator privileges. This is required in-order to upgrade your system with
newer Windows components and to install kernel-mode device drivers (HW.SYS and HWDEVICE.SYS)
required by the GTDIO driver to access resources on your board.
3. The first setup screen to appear is the Welcome screen. Click Next to continue.
4. Enter the folder where software is to be installed. Either click Browse to set up a new folder, or click Next
to accept the default entry of C:\Program Files\Marvin Test Solutions\GTDIO.
5. Select the type of Setup you wish and click Next. You can choose between Typical, Run-Time and
Custom setups. Typical setup type installs all files. Run-Time setup type will install only the files
required for controlling the board either from its driver or from its virtual panel. Custom setup type lets
you select from the available components.

Chapter 3 - Installation and Setup 11
The program will now start its installation. During the installation, Setup may upgrade some of the Windows shared
components and files. The Setup may ask you to reboot after it complete if some of the components it replaced
where used by another application during the installation –do so before attempting to use the software.
You can now continue with the installation to install the board. After the board installation is complete you can test
your installation by starting a panel program that let you control the board interactively. The panel program can be
started by selecting it from the Start, Programs, GTDIO menu located in the Windows Taskbar.
Overview of the GTDIO Software
Once the software installed, the following tools and software components are available:
PXI/PCI Explorer applet –use to configure the PXI chassis, controllers and devices. This is required for
accurate identification of your PXI instruments later on when installed in your system. The applet
configuration is saved to PXISYS.ini and PXIeSYS.ini that are used by Marvin Test Solutions instruments,
the VISA provider and VISA based instruments drivers. In addition, the applet can be used to assign
chassis numbers, Legacy Slot numbers and instruments alias names.
VISA is a standard maintained by the VXI Plug & Play System Alliance and the PXI Systems Alliance
organizations (http://www.vxipnp.org/, http://www.pxisa.org/). VISA provides a standard way for
instrument manufacturers and users to write and use instruments drivers. The VISA resource managers
such as National Instruments Measurement & Automation (NI-MAX) can display and configure
instruments and their address (similar to Marvin Test Solutions’ PXI/PCI Explorer).
GTDIO Panel –use to configure, control and display the board settings.
DIOEasy –Windows application for creating and analyzing vector files used by DIO boards.
GTDIO driver –a DLL (GTDIO32.DLL) located in the Windows System folder used to program and
control the board.
Programming files and examples –interface files and libraries for various programming tools, see later in
this chapter for a complete list of files, programming languages and development tools supported by the
driver.
Documentation –On-Line help and User’s Guide.

Configuring Your PXI System using the PXI/PCI Explorer
To configure your PXI/PCI system using the PXI/PCI Explorer applet follow these steps:
1. Start the PXI/PCI Explorer applet. The applet can be start from the Windows Control Panel or from the
Windows Start Menu, Marvin Test Solutions, HW, PXI/PCI Explorer.
2. Identify Chassis and Controllers. After the PXI/PCI Explorer started it will scan your system for changes
and will display the current configuration. The PXI/PCI Explorer automatically detects systems that have
Marvin Test Solutions controllers and chassis. In addition, the applet detects PXI-MXI-3/4 extenders in
your system (manufactured by National Instruments). If your chassis is not shown in the explorer main
window, use the Identify Chassis/Controller commands to identify your system. Chassis and Controller
manufacturers should provide INI and driver files for their chassis and controllers to be used by these
commands.
3. Change chassis numbers, PXI devices Legacy Slot numbering and PXI devices Alias names. These are
optional steps to be performed if you would like your chassis to have different numbers. Legacy slots
numbers are used by older Marvin Test Solutions or VISA drivers. Alias names can provide a way to
address a PXI device using your logical name (e.g. “DIO1”). For more information regarding these
numbers see the DioSetupInitialization and DioSetupInitializationVisa functions in the DIO
Programming User’s Guide.
4. Save you work. PXI Explorer saves the configuration to the following files located in the Windows folder:
PXISYS.ini, PXIeSYS.ini and GxPxiSys.ini. Click on the Save button to save you changes. The
PXI/Explorer prompt you to save the changes if changes were made or detected (an asterisk sign ‘ *‘ in the
caption indicated changes).
