CHAPTER 2 2 Installation Sections include: • Unpacking • Driver Installation • Hardware Installation • Hardware Uninstallation
Chapter 2 Installation 2.1 Unpacking After receiving your USB-4716 package, please inspect its contents first. The package should contain the following items: • USB-4716 Module • Shielded USB 2.0 Cable (1.8 m) • Companion CD-ROM (DLL driver included) • Startup User Manual The USB-4716 Module harbors certain electronic components vulnerable to electrostatic discharge (ESD). ESD could easily damage the integrated circuits and certain components if preventive measures are not carefully paid attention to.
2.2 Driver Installation We recommend you install the software driver before you install the USB-4716 module into your system, since this will guarantee a smooth installation process. The 32-bit DLL driver Setup program for the USB-4716 module is included on the companion CD-ROM that is shipped with your module package.
For further information on driver-related issues, an online version of the Device Drivers Manual is available by accessing the following path: Start\Programs\Advantech Automation \Device Manager\Device Driver’s Manual USB-4716 User Manual 8
2.3 Hardware Installation Note: Make sure you have installed the software driver before you install the module (please refer to Section 2.2 Driver Installation) After the DLL driver installation is completed, you can now go on to install the USB-4716 module in any USB port that supports the USB 1.1/2.0 standard, on your computer. Please follow the steps below to install the module on your system.
Figure 2.1: Unplug or Eject Hardware Dialog Step3: Select “Advantech USB-4716 Device” and press “Stop” Button. Figure 2.2: Stop a Hardware device dialog box Step4: Unplug your USB device from the USB port. Note: Please make sure that you have closed the application before unplugging the USB device, otherwise unexpected system error or damage may occur.
CHAPTER 3 2 Signal Connections This chapter provides useful information on how to connect input and output signals to the USB-4716 via the I/O connectors.
Chapter 3 Signal Connections 3.1 Overview Maintaining good signal connections is one of the most important factors in ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. 3.2 I/O Connectors USB-4716 is equipped with plug-in screw-terminal connectors that facilitate connection to the module without terminal boards or cables. 3.2.1 Pin Assignment Figure 3.
Figure 3.
3.2.2 I/O Connector Signal Description Table 3.1: I/O Connector Signal Description Signal Name Reference Direction Description AI<0…15> AGND Input Analog Input Channels 0 through 15. AIGND - - Analog Input Ground. AO0 AO1 AGND Output Analog Output Channels 0/1. AOGND - - Analog Output Ground. The analog output voltages are referenced to these nodes. DI<0..7> DGND Input Digital Input channels. DO<0..7> DGND Output Digital Output channels. DGND - - Digital Ground.
3.2.3 LED Indicator Status Description The USB Module is equipped with a LED indicator to show the current status of the device. When you plug the USB device into the USB port, the LED indicator will blink five times and then stay lit to indicate that it is on. Please refer to the following table for detailed LED indicator status information. Table 3.
3.3 Analog Input Connections USB-4716 supports 16 single-ended/ 8 differential (or combination) analog inputs. Each individual input channel is software-selected. 3.3.1 Single-ended Channel Connections The single-ended input configuration has only one signal wire for each channel, and the measured voltage (Vm) is the voltage of the wire as referenced against the common ground. A signal source without a local ground is also called a “floating source”.
3.3.2 Differential Input Connections The differential input channels operate with two signal wires for each channel, and the voltage difference between both signal wires is measured. On USB-4716, when all channels are configured to differential input, up to 8 analog channels are available. If one side of the signal source is connected to a local ground, the signal source is ground-referenced. Therefore, the ground of the signal source and the ground of the card will not be exactly of the same voltage.
3.4 Analog Output Connections (Voltage) USB-4716 provides two analog output channels, AO0 and AO1. Figure 3-3 shows how to make analog output connections on USB-4716. Figure 3.4: Analog Output Channel Connections 3.5 Trigger Source Connections 3.5.1 Internal Pacer Trigger Connection USB-4716 provides two 16-bit counters connected to a 10 MHz clock. Counter 0 is a counter that counts events from an input channel. Counter 1 is a 16-bit timer for pacer triggering.
3.6 Field Wiring Considerations • When you use USB-4716 to acquire data from outside, noises in the environment might significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference running signal wires between signal sources and the USB-4716.
