Description
The 6025E features 16 channels (eight differential) of analog input, two channels of analog output, a 100-pin connector, and 32 lines of digital I/O. The 6024E features 16 channels of analog input, two channels of analog output, a 68-pin connector and eight lines of digital I/O. The 6023E is identical to the 6024E, except that it does not have analog output channels.
These devices use the National Instruments DAQ-STC system timing controller for time-related functions. The DAQ-STC consists of three timing groups that control analog input, analog output, and general-purpose counter/timer functions. These groups include a total of seven 24-bit and three 16-bit counters and a maximum timing resolution of 50 ns. The DAQ-STC makes possible such applications as buffered pulse generation, equivalent time sampling, and seamless changing of the sampling rate.

With many DAQ devices, you cannot easily synchronize several measurement functions to a common trigger or timing event. These devices have the Real-Time System Integration (RTSI) bus to solve this problem. In a PCI system, the RTSI bus consists of the National Instruments RTSI bus interface and a ribbon cable to route timing and trigger signals between several functions on as many as five DAQ devices in your computer. In a PXI system, the RTSI bus consists of the National Instruments RTSI bus interface and the PXI trigger signals on the PXI backplane to route timing and trigger signals between several functions on as many as seven DAQ devices in your system.
These devices can interface to an SCXI system—the instrumentation front end for plug-in DAQ devices—so that you can acquire analog signals from thermocouples, RTDs, strain gauges, voltage sources, and current sources. You can also acquire or generate digital signals for communication and control.
Using PXI compatible products with standard CompactPCI products is an important feature provided by PXI Specification, Revision 1.0. If you use a PXI compatible plug-in card in a standard CompactPCI chassis, you cannot use PXI-specific functions, but you can still use the basic plug-in card functions. For example, the RTSI bus on your PXI E Series device is available in a PXI chassis, but not in a CompactPCI chassis. The CompactPCI specification permits vendors to develop sub-buses that coexist with the basic PCI interface on the CompactPCI bus.
Compatible operation is not guaranteed between CompactPCI devices with different sub-buses nor between CompactPCI devices with sub-buses and PXI. The standard implementation for CompactPCI does not include these sub-buses. Your PXI E Series device works in any standard CompactPCI chassis adhering to PICMG CompactPCI 2.0 R2.1 core specification. PXI specific features are implemented on the J2 connector of the CompactPCI bus. Table 3-3, Pins Used by PXI E Series Device, lists the J2 pins used by your PXI E Series device.
Your PXI device is compatible with any Compact PCI chassis with a sub-bus that does not drive these lines. Even if the sub-bus is capable of driving these lines, the PXI device is still compatible as long as those pins on the sub-bus are disabled by default and not ever enabled. Damage can result if these lines are driven by the sub-bus.
PCI device installation
1. Turn off and unplug your computer.
2. Remove the top cover of your computer.
3. Remove the expansion slot cover on the back panel of the computer.
4. Touch any metal part of your computer chassis to discharge any static electricity that might be on your clothes or body.
5. Insert the device into a 5 V PCI slot. Gently rock the device to ease it into place. It may be a tight fit, but do not force the device into place.
6. Screw the mounting bracket of the device to the back panel rail of the computer.
7. Visually verify the installation.
8. Replace the top cover of your computer.
9. Plug in and turn on your computer.
