Analog Access to AMTI Force Plates

  1. Accessing AMTI force plates through AD requires the use of camera trigger synchronization. Connect one end of the synchronization cable to the AUX port at the back of the camera with IP address 201, and the other end to the NI AD acquisition card using an adapter and jumper cable. Based on the labels such as Fx and Fy on the AMTI analog signal cable, correctly connect the analog signal cables to the NI AD acquisition card according to the wiring requirements of the AMTI force plate.

  2. Driver Installation:

    • Ensure the signal amplifier is connected to the force plate and that the amplifier is powered on.

    • In the Control Panel, search for "Device Manager" and click on it.

    • Find "Other devices, " marked with a yellow warning (16.1.3.1).

    • Right-click and select "Update Driver, " then choose "Browse my computer for driver software." Using AMTI's USB drive, find the "64-bit Drivers Ver. 3.4.7" folder in the specified path on the USB. Select this folder and click "Next." After the progress bar completes, "Windows has successfully updated your drivers" will be displayed, indicating that the driver installation is complete.

    • If you don't have a driver folder, please contact the AMTI manufacturer to obtain it.

  3. Install "NetForce":

    • For installing the "NetForce" software, please contact our engineering technical staff to obtain the "NetForce Ver" software installation package. Click "Setup" to start the installation and follow the prompts to complete the process.

  4. Configure the matrix in "NetForce" software:

    • Open the "NetForce" software, click "Setup" at the top, and select "Hardware Installation" (16.1.3.2). In the "Hardware Installation" window, select "Optima \Gen-5" from the dropdown list under "New Installation" (16.1.3.3) and click "Install".

    • In the pop-up "AMTI System Configuration" window, select "Fully Conditioned" from the dropdown list under "Analog Outputs" (16.1.3.4). Click the Optima button at the bottom of the window, then click Continue, and finally click Browse. In the subsequent window (16.1.3.5), navigate to the path and select the "10382M.bcf" file (16.1.3.6). Click Open and wait for the download to finish. Click "Done" to exit once the download is complete.

    • In the Installed Amplifier section of the AMTI System Configuration window, click the "Configure" button underneath. In the pop-up window, set all Excitation values for Fx/Fy/Fz/Mx/My/Mz to 10 and set all Gain values to 1000. Click the "Analog Adjust" button at the bottom and record all six values in the Analog Scale Factor row (16.1.3.7). Divide 1000 by each value in the Analog Scale Factor to get the matrix value in the XINGYING software. Click "Apply All, " then "OK" to close the window.

    • In the AMTI System Configuration window, click "Apply" and then "Save" to preserve this configuration for future use. Click "Done" to exit. When exiting the NetForce software, you will be prompted to save these settings (16.1.3.8); click "Yes" to automatically close the software. Once NetForce is closed, unplug the USB cable connecting the AMTI force plate amplifier to your computer.

  5. Open XINGYINM, click on the dynamometer menu bar, and select "Force Platform Configuration." Then click the "+" to add a force plate. On the right, set the parameters for the AMTI force plate. From the top left to the bottom right of the calibration matrix, enter the matrix values derived from the "AMTI NetForce" software, then click "Apply."

  6. Click on the dynamometer menu bar and select "Analog Configuration." In the Analog Configuration window, configure the analog channels for AMTI. Right-click in the list and select "AMTI--FP1." Configure the range for each channel according to the output range of the test platform. Each analog channel can select ranges like +/-10mV, +/-10V, etc., from the "Range" drop-down menu. Click the "Select" button at the top left of the window to select all analog channels.

  7. In the Force Platform Configuration window, check the box for Analog Access (16.1.3.9). Connect the camera, and click "Play" to use the AMTI force plate in Live mode.

USB Access to AMTI Force Plates

  1. To connect AMTI force plates via USB, power on the amplifier, ensure the amplifier's power switch is turned on, and connect the force plate cable to the amplifier's "TRANSDUCER INPUT" port.

  2. Connect one end of the synchronization cable to the AUX port at the back of the camera with IP address 201, and connect the other end’s white synchronization cable to the "GENLOCK/TRIGGER INPUT" port on the amplifier.

  3. Insert the USB cable into the USB port on the amplifier, and connect the other end of the USB cable to the computer where the XINGYING software is installed.

  4. Open the XINGYING software, open the Force Platform Configuration. In the "Other Configurations" section at the bottom of the Force Platform Configuration window, check the "Digital Force Plate (USB)" option, click "+", and it will automatically add a force plate. Select the force plate name, and in the "Force Plate Specifications" on the right side of the window, set the type to AMTI and adjust the length and width according to the size of the force plate. The parameters under "Orientation in Volume, Position in Volume" can use the system's default parameters, or you can modify them according to your needs. The "Serial ID" at the bottom of the window will display the serial number of the force plate. After configuring the force plate parameters, click the "Apply" button to save this configuration (16.3.10).

  5. Close the settings window, connect the camera, and click the play button in the Live 3D view mode. At this point, the AMTI force plate, which has been connected via USB, has been added to the 3D view and is ready to be used.
