Chapter Introduction 1 This chapter describes the AT E Series boards, lists what you need to get started, describes the optional software and optional equipment, and explains how to unpack your AT E Series board. About the AT E Series Thank you for buying a National Instruments AT E Series board. The AT E Series boards are the first completely Plug and Play-compatible multifunction analog, digital, and timing I/O boards for the PC AT and compatible computers. This family of boards features

Chapter 1 Introduction timing event. The AT E Series boards have the Real-Time System Integration (RTSI) bus to solve this problem. The RTSI bus consists of our RTSI bus interface and a ribbon cable to route timing and trigger signals between several functions on as many as five DAQ boards in your PC. The AT E Series boards can interface to an SCXI system so that you can acquire over 3,000 analog signals from thermocouples, RTDs, strain gauges, voltage sources, and current sources.

Chapter 1 Introduction Software Programming Choices There are several options to choose from when programming your National Instruments DAQ and SCXI hardware. You can use LabVIEW, LabWindows/CVI, NI-DAQ, or register-level programming. LabVIEW and LabWindows/CVI Application Software LabVIEW and LabWindows/CVI are innovative program development software packages for data acquisition and control applications. LabVIEW uses graphical programming, whereas LabWindows/CVI enhances traditional

Chapter 1 Introduction NI-DAQ has both high-level DAQ I/O functions for maximum ease of use and low-level DAQ I/O functions for maximum flexibility and performance. Examples of high-level functions are streaming data to disk or acquiring a certain number of data points. An example of a low-level function is writing directly to registers on the DAQ device. NI-DAQ does not sacrifice the performance of National Instruments DAQ devices because it lets multiple devices operate at their pea

Chapter 1 Introduction You can use your AT E Series board, together with other PC, AT, EISA, DAQCard, and DAQPad Series DAQ and SCXI hardware, with NI-DAQ software for PC compatibles. Register-Level Programming The final option for programming any National Instruments DAQ hardware is to write register-level software. Writing register-level programming software can be very time-consuming and inefficient and is not recommended for most users. Even if you are an experienced register-level

Chapter 1 Introduction Custom Cabling National Instruments offers cables and accessories for you to prototype your application or to use if you frequently change board interconnections. If you want to develop your own cable, however, the following guidelines may be useful: • For the analog input signals, shielded twisted-pair wires for each analog input pair yield the best results, assuming that you use differential inputs. Tie the shield for each signal pair to the ground reference

Chapter 1 Introduction Unpacking Your AT E Series board is shipped in an antistatic package to prevent electrostatic damage to the board. Electrostatic discharge can damage several components on the board. To avoid such damage in handling the board, take the following precautions: • Ground yourself via a grounding strap or by holding a grounded object. • Touch the antistatic package to a metal part of your computer chassis before removing the board from the package. • Remove the board
