The step-by-step instructions on how to build your own applications using each development tool will be given in the Device Drivers Manual. Moreover, a rich set of example source code is also given for your reference. 1.5.
1.5.2 Programming with Device Drivers Function Library Advantech 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 C++, Visual Basic, Delphi and C++ Builder. 1.5.3 Troubleshooting Device Drivers Error Driver functions will return a status code when they are called to perform a certain task for the application.
CHAPTER 2 2 Installation This chapter has a package item checklist, proper instructions about unpacking and step-by-step procedures for both driver and USB installation..
Chapter 2 Installation 2.1 Unpacking After receiving your USB-4761 package, please inspect its contents first. The package should contain the following items: • USB-4761 Module • Shielded USB 2.0 Cable (1.8 m) • Companion CD-ROM (DLL driver included) • User Manual The USB-4761 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-4761 module into your system, since this will guarantee a smooth installation process. The 32-bit DLL driver Setup program for the USB-4761 module is included on the companion CD-ROM that is shipped with your module package. Please follow the steps below to install the driver software: Step 1: Insert the companion CD-ROM into your CD-ROM drive.
Step3: Click Continue, and select the Installation option Step4: Select the specific device and then just follow the installation instructions step by step to complete your device driver installation and setup. 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 \Advantech Device Manager\Device Driver’s Manual 2.
Figure 2.2: Device Name on the Device Manager Note: If your module is properly installed, you should see the device name of your module listed on the Device Manager tab. If you see your device name listed, but marked with an exclamation sign “!” (Fig. 2-4), it means your module has not been correctly installed. In this case, remove the module from Device Manager by selecting its device name and press the Remove button. Then go through the driver installation process again.
Figure 2.3: The (!) Indicates Improper Installation After your module is properly installed with your system, you can now configure your device using the Advantech Device Manager that has itself already been installed on your system during driver setup. A complete device installation procedure should include device setup, configuration and testing. The following sections will guide you through the Setup, Configuration and Testing of your device. 2.
Step2: You can view the device(s) already installed on your system (if any) in the Installed Devices list box. If you haven’t installed any devices, you might see a blank list. Figure 2.4: Device Manager Dialog Box Note: If you have properly installed the device driver but still can’t find it in Advantech Device Manager, please close the Advantech Device Manager and restart it. 2.4.2 Configuring the Device Step 3: Click “Setup” button and you will see the “Device Setting “dialog box as follow.
Figure 2.5: The Device Setting Dialog Box Note: Please refer to the software manual Start/Programs/Advantech Automation/Advantech Device Manager/Device Driver’s Manual for the firmware download utility guidance and further information. 2.5 Device Testing Following the Setup and Configuration procedures to the last step described in the previous section, you can now proceed to test the device by clicking the Test Button in the I/O Device Installation dialog window.
2.5.1 Testing Digital Input Function Click the Digital Input tab to show the Digital Input test panel as seen below. By the color of the LEDs, you can easily discern whether the status of each digital input channel is high or low. Figure 2.6: Digital Input Tab in Device Test Dialog 2.5.2 Testing Digital Output Function Click the Digital Output tab to bring up the Digital Output test panel as shown below.
. Figure 2.7: Digital Output Tab in Device Test Dialog Only after your module device is properly set up, configured and tested, can the device installation procedure be considered complete. After the device installation procedure is completed, you can safely proceed to the next chapter, Signal Connections. 2.
Step2: Right click the “Unplug or Eject Hardware” icon on your task bar. Figure 2.8: Unplug or Eject Hardware Dialog Step3: Select “Advantech USB4711 Device” and press “Stop” Button. Figure 2.
