Signal Description

NI 656X Front Panels and Connectors

The NI 656X front panels contain four connectors—three SMB jacks (CLK IN, PFI 0, and CLK OUT) and one 73-pin 12x Infiniband connector (DIGITAL DATA & CONTROL, or DDC).
Figure 10 shows the NI 6561 front panels and pinout, which are identical to those of the NI 6562. Signals marked with an asterisk represent the complementary terminal for the differential signal of the same name. The DDC signals are described in Table 6. The SMB connectors are the same as those described in Table 7, and the LEDs are the same as those described in Tables 8 and 9.
Note If you are designing a custom cabling solution with connector
(779157-01) and cable (192744-01), the NI 656X pinout is reversed at the end connector. For example, the signal shown on pin 1 shown in the previous figure would map to pin 73 at the end connector.

Appendix B: Troubleshooting

Device Front Panel ACCESS LED on PXI Module is Off When PXI Chassis is On

If the ACCESS LED is not lit after you power on the PXI chassis, a problem may exist with the PXI power rails, a hardware device, or the LED.
Note The LEDs may not light until the device has been configured
in MAX. Before troubleshooting this issue, verify that the device appears in MAX.
Troubleshoot this issue by completing the following steps:
1. Power off your PXI chassis.
2. Disconnect any signals from the PXI module front panel.
3. Remove the PXI module and inspect for signs of damage. Do not reinstall a damaged device.
4. Reinstall the PXI module using the procedure described in step 5. Installing the Hardware.
5. Power on your PXI chassis.
6. Verify the device appears in MAX.
7. Reset the device in MAX and perform a self-test. Refer to step 6. Configuring and Testing in MAX for information on performing device resets and self-tests in MAX.
8. If the ACCESS LED still fails to light, contact NI support at
ni.com/support.
NI Digital Waveform Generator/Analyzer Guide 26 ni.com

Device Does Not Appear in MAX

Complete the following steps if the NI device does not appear in MAX:
1. In the MAX Configuration pane, click Devices and Interfaces to expand the category.
2. Click NI-DAQmx Devices and press <F5> to refresh the list of installed devices.
3. If the device is still not listed, power down the system, ensure the device is correctly installed, and restart.
4. If the device still does not appear under NI-DAQmx Devices, contact NI support at
ni.com/support.

Device Failed the Self-Test

The MAX self-test performs a brief test of device resources. If the device does not pass the self-test, complete the following steps:
1. Reboot your system.
2. Launch MAX and perform the self-test again. If the device still fails the self-test, proceed to step 3.
3. Uninstall and reinstall NI-HSDIO.
4. If the device still fails the self-test, contact NI support at ni.com/

I Received a Thermal Shutdown Error

I received the kErrorDeviceShutDownDueToHighTemp error, and my device shut down. What should I do next?
To re-enable your device after a thermal shutdown, you must perform a hard reset, in which the device integrated circuits (ICs) are reloaded. To re-enable your device after thermal shutdown, complete the following steps:
1. Power down the computer or chassis that contains the device.
2. Review the procedure in step 5. Installing the Hardware and make any necessary adjustments to ensure that your device is effectively cooled.
3. Call
niHSDIO_ResetDevice (NI-HSDIO Reset Device VI) or perform
a device reset in MAX. For more information on performing a device reset in MAX, refer to step 6. Configuring and Testing in MAX. The thermal shutdown error continues to be reported until the device has been successfully reset.

Performance Issues Using MXI Connection

When using a MXI connection to control the PXI chassis, the MXI Optimization Application must be run prior to using the NI device. By default, this application runs automatically when Windows starts. Use of a MXI connection without running this application may result in a
exceeded
performance issue when using the NI device.
If you are experiencing errors and are uncertain whether the MXI Optimization Application ran, navigate to Start»Programs»National Instruments MXI and select MXI Optimization to run the application.
If the application is not installed, refer to the software CD included with the MXI kit to install the software. After installation, you may be required to reboot the computer before using the MXI Optimization Application.
If you continue to have initialization or performance issues, refer to the MXI documentation at Start»Programs»National Instruments MXI, or visit NI Technical Support at
