Installing and Configuring

Refer to the readme.htm file that accompanies the NI-Sync software for software installation directions.

The following are general installation instructions. Consult the chassis user manual or technical reference manual for specific instructions and warnings about installing new modules.

1. Power off and unplug the chassis.
   Caution Do not install the PXI-6683 Series in the system controller slot (Slot 1) of a chassis.
2. Choose an available slot in the chassis. Refer to the following table for more information about functionality.
   • PXI-6683—Install in an available PXI slot. PXI triggers are accessible from any PXI slot, but the PXI-6683 can replace PXI_CLK10 and control PXI_STAR triggers only if it is installed in the system timing slot of a PXI chassis.
   • PXI-6683H—Install in an available PXI slot. If you are using a PXI Express (PXIe) system, install the PXI-6683H in an available PXI or PXIe/hybrid slot. Unlike the PXI-6683, the PXI-6683H cannot replace PXI_CLK10 or drive PXI_STAR triggers.

     Table 1. PXI/PXI Express Slot Type Compatibility

     NI PXI Board	PXI System Timing Slot	PXI Peripheral Slot	PXI Express Hybrid Slot
     PXI-6683	X*	X†	—
     PXI-6683H	X†	X†	X†
     *Compatible: PXI_CLK10, PXI_CLKIN, PXI_STAR, PXI_TRIG functionality available. †Compatible: PXI_TRIG functionality available

3. Remove the filler panel for the PXI or PXI Express hybrid slot you chose in step 2.
4. Ground yourself using a grounding strap or by touching a grounded object. Follow the ESD protection precautions described in the Unpacking section.
5. Remove any packing material from the front panel screws and backplane connectors.
6. Insert the PXI-6683 Series module into the PXI or PXI Express hybrid slot. Use the injector/ejector handle to fully insert the module into the chassis.
7. Screw the front panel of the module to the front panel mounting rail of the chassis.
8. If adjacent slots are not populated, use EMC filler panels to cover the opening.
   Caution To ensure the specified EMC performance, you must install PXI EMC filler panels (National Instruments part number 778700-01) in all open chassis slots.
9. Visually verify the installation.
10. Plug in and power the chassis.

The PXI-6683 Series is now installed.

The PXI-6683 Series is completely software configurable. The system software automatically allocates all module resources.

The two LEDs on the front panel provide information about module status. The PXI-6683 Front Panel and LEDs section describes the LEDs in greater detail.
