Chapter Introduction This chapter will provide informa- tion on the features of the PCIE- 1840 cards, a quick installation guide, together with some brief information on software and accessories. Sections include: Features Applications Installation Guide Software Overview ...
1.2.2 BoardID Switch The PCIE-1840 has a built-in DIP switch that helps define each card’s ID when multi- ple PCIE-1840 cards have been installed on the same PC chassis. The BoardID set- ting function is very useful when building a system with multiple PCIE-1840 cards.
Installation Guide Before you install your PCIE-1840 card, please make sure you have the following components: PCIE-1840 DA&C card PCIE-1840 Startup Manual Driver software Advantech DAQNavi SDK and drivers (included in the companion CD-ROM) Auto-Calibration Board PCLD-8841 ...
C++ Builder For instructions on how to begin programming works in each development tool, Advantech offers a Tutorial Chapter in the DAQNavi SDK Manual for your reference. Refer to the corresponding sections in this chapter on the DAQNavi SDK Manual to begin your programming efforts.
1.6.2 Programming with DAQNavi Device Drivers Function Library Advantech DAQNavi Device Drivers offer a rich function library that can be utilized in various application programs. This function library consists of numerous APIs that support many development tools, such as Visual Studio.Net, Visual C++, Visual Basic, Delphi and C++ Builder.
PC or transport it elsewhere. Driver Installation We recommend you install the driver before you install the PCIE-1840 card into your system, since this will guarantee a smooth installation process. The Advantech DAQNavi Device Drivers Setup program for the PCIE-1840 card is included in the companion DVD-ROM that is shipped with your DA&C card package.
2.2.1 Device Auto Installation (Recommended) You can install the PCIE-1840 module in any PCI Express slot on your computer. Fol- low the steps below to install the module on your system. Turn off your computer and unplug the power cord and cables. TURN OFF your computer before installing or removing any components on the computer.

After your card is properly installed and configured, you can go to the Device Test page to test your hardware by using the testing utility supplied. Figure 2.3 The Device Testing of PCIE-1840 For more detailed information, refer to the DAQNavi SDK Manual or the User Inter- face Manual in the Advantech Navigator.
Chapter Signal Connections This chapter provides useful information about how to connect input and output signals to the PCIE-1840 cards via the I/O con- nector. Sections include: Overview Switch Settings Signal Connections Field Wiring Considerations...
Jumper Settings Setting the BoardID Switch (SW1) The PCIE-1840 has a built-in DIP switch (SW1), which is used to define each card's board ID. You can determine the board ID on the register as shown in Table 3.1. When there are multiple cards on the same chassis, this board ID setting function is useful for identifying each card's device number through board ID.
Signal Connections Pin Assignment There are four BNC and one 19-pin connectors on the PCIE-1840, which connects to BNC and PCL-10119 HDMI cables. Figure 3.1 and Figure 3.2 show the pin assign- ments for the BNC and 19-pin I/O connector separately, and Table 3.1 shows its I/O connector signal description.
3.3.2.1 Digital Trigger Connections You can configure the PCIE-1840 to trigger in response to digital signals on DTRG0 or DTRG1 pin of the HDMI connector, located on the device front panel. The trigger circuit can respond either to a rising or a falling edge. The trigger signal must comply to 3.3 V or 5 V TTL voltage levels.

3.3.2.2 Analog Trigger You can configure the PCIE-1840 analog trigger circuitry to monitor any input chan- nel from which you acquire data. Choosing an input channel as the trigger channel does not influence the input channel acquisition capabilities. The trigger circuit generates an internal digital trigger based on the input signal and the defined trigger levels.
3.3.3 PCLD-8841 Signal Connection To ensure the accuracy of PCIE-1840 would not drift by time, periodical calibrations are necessary to make the performance match its specification. PCIE-1840 provides two methods for calibration, manual-calibration and self-calibration with PCLD-8841. By manual calibration, PCIE-1840 could achieve higher accuracy but it takes more time and is suitable for the users who require a single channel calibration.
Field Wiring Considerations When you use PCIE-1840 cards to acquire data from outside, noises in the environ- ment might significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference run- ning signal wires between signal sources and the PCIE-1840 card.

1840. They will lead to voltage swings in time domain and unexpected spurs in fre- quency domain. These mismatches include offset mismatch, gain mismatch, and clock phase mismatch. Though PCIE-1840 is capable to calibrate the gain error under TIS, the non-perfectly matched ADCs would still degrade the SNR ratio. Users should take this unavoidable degradation into consideration, especially in frequency domain applications.
