informs other programs about which devices reside in the system and how they are configured.
MAX is automatically installed with 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. (PXI and PXI Express devices only) 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.
4. (Controllers for FlexRIO only) Your device appears under the Remote Devices section.
Cables
Caution You must operate the NI 6589 with shielded cables and shielded
accessories to ensure compliance with the EMC requirements defined in the NI 6589
Specifications. Do not use unshielded cables or accessories unless they are installed
in a shielded enclosure with properly designed and shielded input/output ports and
are connected to the NI 6589 using a shielded cable. If unshielded cables or
accessories are not properly installed and shielded, the EMC specifications for the
NI 6589 are no longer guaranteed.
Use a shielded 50 Ω coaxial cable with an SMA plug end to connect to the PFI 0 and
CLOCK IN connectors on the NI 6589 front panel. Use the NI SHB12X-B12X shielded cable
(NI part number 192344-01) or the NI SHB12X-H3X24 differential flying-lead cable (NI part
number 196236-1R5) to connect to the DDC connector. You can also connect the
NI SMA-2164 accessory to the NI 6589 through the SHB12X-B12X shielded cable for testing
and debugging.
Note If you design a custom cabling solution with the DDC connector (779157-01)
and SHB12X-B12X shielded cable (192344-01), the NI 6589 pinout is reversed at
NI 6589 Getting Started Guide | © National Instruments | 5

the end connector. For example, the signal shown on pin 1 maps to pin 73 at the end
connector.
The following NI cables and accessories are not properly shielded for EMC-compliant use
with the NI 6589:
• NI SMA-2164 accessory
• NI SHB12X-H3X24 differential flying-lead cable
Note Whether you use NI cables and accessories or design your own, terminate
cables properly to avoid improper measurements caused by signal reflections,
overshoot, and undershoot.
Accessories
The NI SMA-2164 test fixture is a breakout box for differential signals. This fixture provides
an easy way to connect to other devices for testing and debugging.
The following figure shows how to connect the differential DDC connector to the
NI SMA-2164, using the NI SHB12X-B12X cable. For more information about using the
NI SMA-2164, refer to the NI SMA-2164/2165 Test Fixture User Guide.

Component-Level Intellectual Property (CLIP) on page 12
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for
HDL IP integration. FlexRIO devices support two types of CLIP: user-defined and
socketed.
Component-Level Intellectual Property (CLIP)
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for HDL
IP integration. 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 it 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 FlexRIO adapter module ships with socketed CLIP items that add module I/O to the
LabVIEW project.

Clocking
The clocks on the NI 6589 control the sample rate and other timing functions on your FlexRIO
system. The following figure shows the NI 6589 clock sources routed through the crosspoint
switch. The Generation Bank I/O clock, PFI Bank I/O clock, and Global clock are all sourced
by the crosspoint switch. The Acquisition Bank I/O clock can be sourced from the crosspoint
switch or accessed directly through the Strobe Bypass path.
Note Only the Acq_IO_Clock_Source signal can use the STROBE Bypass path. If
Acq_IO_Clock_Source is set to Strobe Bypass, then Gen_IO_Clock_Source,
PFI_IO_Clock_Source, and IO_Module_Clock_1_Source cannot be set to Strobe
From Crosspoint Switch.

In software, each clock output terminal is accessed with a U8 data type. The following table
shows the values of the crosspoint switch clock options.
Table 7. Clock Values
Value Clock Option
0Tristate—Output disabled (high impedance).
2Sync Clock (PXI Express Only)—Clock from PXI Express backplane. You can
select PXI_CLK10 or DStarA in the Details category of the IO Module Properties
dialog box.
3Adapter Module Onboard Clock—Clock generated from the Si570 clock chip.
4Strobe From Crosspoint Switch—LVDS STROBE signal from crosspoint switch.
Use this setting to route the LVDS STROBE signal to multiple I/O clocks.
5Strobe Bypass—LVDS STROBE bypasses the crosspoint switch. The propagation
delay of the Strobe Bypass exactly matches the propagation delay of the data
channels. This setting is ideal for source- synchronous applications.
