Connectivity Options
NI recommends that you use the following cables with the NI 6581/6581B:
• NI SHC68-C68-D4 cable (part number 196275-01)—Shielded cable designed for single-
ended, high-speed digital signal transmission. This cable has individual microcoaxial
50 Ω lines for each signal.
• NI C68-C68-D4 cable (part number 195949-01)—Unshielded, single-ended 50 Ω cable.
• NI SHC68-H1X38 cable (part number 192681-1R5)—Single-ended, 50 Ω cable that
breaks out each single-ended signal into two 0.1 inch header receptacles, one receptacle
each for the signal and ground. It provides an easy way to connect the NI 6581/6581B to
various types of devices and circuits for interfacing, testing, or analysis.
This cable offers connectivity similar to that found on a typical logic analyzer, so you can use
it in logic analyzer-type applications. Unlike a typical logic analyzer, however, this cable also
allows for simultaneous pattern generation and acquisition so that you can use it in stimulus/
response applications as well. The following figure shows the parts locator diagram for the
single-ended digital flying lead cable.

1. 68-pin VHDCI Connector
2. Removable Sleeving
3. Lead Pairs
You can use the SHC68-C68-D4 or C68-C68-D4 cable with the following accessories:
• NI CB-2162—Single-ended digital I/O (DIO) accessory that can access the signals on the
68-pin DDC connector, terminate the DIO channels, and provide a platform for circuit
prototyping and DUT testing.
• NI SMB-2163—Breakout box that offers coaxial SMB connectors for each channel on
the DDC connector, providing an easy way to connect to other devices for testing and
debugging.
Note When connecting to the CB-2162 or SMB-2163 accessories, NI 6581/6581B
signals map in the following ways:
• P0.<0..7> map to DIO <0..7>
• P1.<0..7> map to DIO <8..15>
• P2.<0..7> map to DIO <16..23>
• GLOBAL CLOCK <0..1> map to STROBE
For information about connecting I/O signals, refer to the NI FlexRIO Help, available from the
Start menu and at ni.com/manuals.
Power Options
You can power the NI 6581/6581B internally, or externally through a variable power supply.
The following diagram illustrates a power circuitry diagram with an external variable power
supply.

Using External Power
Use the power connector to externally power the NI 6581/6581B. If you do not want to use the
predefined internal voltages, you can select external power in software for one or both DDC
connectors. Complete the following steps to wire a variable power supply to the power
connector with 20–26 AWG wires.
1. Using wire strippers, carefully remove 11 mm (0.43 in.) of insulation from the signal
wires.
2. Wire the voltage output of the power supply to the +VA terminal and/or +VB terminal,
depending which DDC connector(s) you want to power. Press a small flathead
screwdriver on the spring terminal lever to open the terminal, and insert the wire into the
spring terminal opening.
NI 6581/6581B Getting Started Guide | © National Instruments | 9

3. Wire the ground of the power supply to the GND terminal of the power connector.
The NI 6581/6581B external power connector ground connection references an external
power supply to the PXI system. The external power connector does not provide any
means of isolation; therefore, use care when connecting a non-isolated supply to the
external power connector.
Using a grounded power supply as the external power source may cause ground loops
that increase noise on the power rails. NI recommends that you use a floating source that
is ground referenced to the PXI chassis using the ground connection provided by the
external power ground connector on the NI 6581/6581B.
For the maximum external power supply limit, refer to the NI 6581/6581B Specifications,
available from the Start menu and at ni.com/manuals.

NI 6581/6581B Component-Level Intellectual
Property (CLIP)
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for HDL
IP integration. NI FlexRIO devices support two types of CLIP: user-defined and socketed.
•User-defined CLIP allows you to insert HDL IP into an FPGA target, enabling VHDL
code to communicate directly with an FPGA VI.
•Socketed CLIP provides the same IP integration of the user-defined CLIP, but also allows
the CLIP to communicate directly with circuitry external to the FPGA. Adapter module
socketed CLIP allows your IP to communicate directly with both the FPGA VI and the
external adapter module connector interface.
The following figure shows the relationship between an FPGA VI and the CLIP.

The NI 6581/6581B ships with socketed CLIP items that add module I/O to the LabVIEW
project.
NI 6581 CLIP
This CLIP provides read/write access to all digital I/O (DIO) channels using a single channel-
based interface. Each grouping of eight I/O channels has a write enable signal. In the
LabVIEW FPGA Module, each DIO channel is accessed using a Boolean signal.
Refer to Knowledge Base 6NND5NOA for a list of pin assignments to use when modifying the
socketed CLIP used by an NI 6581/6581B.

Unpacking
The NI 6581/6581B modules ship in antistatic packages to prevent electrostatic discharge from
damaging module components. To prevent such damage when handling the modules, ground
yourself using a grounding strap or by holding a grounded object, such as your computer
chassis, and complete the following steps:
1. Touch the antistatic package to a metal part of the computer chassis before removing the
module from the package.
Caution Never touch the exposed pins of connectors.
2. Remove each module from the package and inspect it for loose components or any other
sign of damage.
Notify NI if the modules appear damaged in any way. Do not install a damaged module into
the chassis.

Confirming that Measurement & Automation Explorer
(MAX) Recognizes the Device
Use Measurement & Automation Explorer (MAX) to configure your National Instruments
hardware. MAX informs other programs about which devices reside in the system and how
they are configured. MAX is automatically installed with NI FlexRIO Support.
1. Launch MAX by navigating to Start»All Programs»National Instruments»NI MAX or
by clicking the NI MAX desktop icon.
2. In the Configuration pane, double-click Devices and Interfaces to see the list of installed
devices. Installed devices appear under the name of their associated chassis.
3. Expand your Chassis tree item. MAX lists all devices installed in the chassis. Your
default device names may vary.
Note If you do not see your hardware listed, press <F5> to refresh the list of
installed devices. If the device is still not listed, power off the system, ensure
the device is correctly installed, and restart.

2. Tighten the captive screws on the NI FlexRIO adapter module to secure it to the
NI FlexRIO FPGA module. NI recommends using the laser-tipped screwdriver (part
number 748677-01) included in the NI 6581/NI 6581B packaging.
3. Launch LabVIEW to begin configuring your NI FlexRIO system.
Note MAX only recognizes FPGA modules that are in the chassis. Your
adapter module will not appear in MAX.
Installing PXI EMC Filler Panels
To ensure specified EMC performance, PXI EMC filler panels must be properly installed in
your NI FlexRIO system. The PXI EMC filler panels (National Instruments part number
778700-01) must be purchased separately.

1. Remove the captive screw covers.
2. Install the PXI EMC filler panels by securing the captive mounting screws to the chassis,
as shown in the figure below. Make sure that the EMC gasket is on the right side of the
PXI EMC filler panel.

Note You must populate all slots with a module or a PXI EMC filler panel to
ensure proper module cooling. Do not over tighten screws (2.5 lb · in.
maximum). For additional information about the use of PXI EMC filler panels
in your PXI system, visit ni.com/info and enter emcpanels.
Uninstalling the Hardware
Hot Surface If the module has been in use, it may exceed safe handling
temperatures and cause burns. Allow the module to cool before removing it from the
chassis.
1. Caution Disconnect or disable any external RF, clock, or digital connections
to the NI 6581/6581B front panel. Applying external signals while the device is
powered off may cause damage.
Disconnect any cables from the module front panel connectors.
2. Power off the chassis.

3. Ground yourself with a grounding strap or touch a grounded metal surface.
4. Unlatch the module by pushing down on the ejector handle.
5. Hold the module by the ejector handle and remove it from the slot.
Store the module in the original antistatic packaging when not in use to avoid damage.
