Cometa electromyography receiver box is connected to the computer via USB and requires driver installation.
Device Manager -> Other devices -> Update driver -> Browse my computer for drivers -> Choose the directory where the driver is located -> Scan for automatic installation.
The receiver box is connected to the PC using a USB cable.
After powering on, the green light will be lit for normal communication with the signal transmitter. If there is no proper connection, the light will not be lit. A yellow light indicates low transmitter battery.
Open the software, click on third-party devices, then click on channels to configure the electromyography channels with a range of 500mV.
Click on EMG Configuration and check Cometa EMG.
Connect the lens, click on play, then click on the analog chart on the software, go to the edit page, and enable auto-fit.
If the computer has the "Ditect" camera driver installed, the Wave X receiver may be incorrectly recognized as a "Ditect" device upon connection to the computer, causing Wave X to not function properly on the computer. In such a case, uninstall the "Ditect" driver from the Device Manager (16.2.4.1), and then proceed with the installation of the Wave X driver after uninstalling.
Connect the dedicated Wave X receiver to the computer using a USB cable. Open the Device Manager, expand the "Other devices" list, select the "WestBridge" device with a yellow exclamation mark (16.2.4.2). Right-click and choose "Update driver." Select "Browse my computer for driver software," choose the folder where the Wave X driver is located, and click "Next" to install the driver (16.2.4.3).
After successful installation, the system will recognize the device as "EMG and Motion X Device" (16.2.4.4).
Power on the receiver by connecting it to a power source and flipping the switch. Insert the trigger sync line into the back of the receiver (16.2.4.5).
Connect the BNC to RCA adapter cable to the trigger sync line slot. Insert the RCA head of the sync line into the trigger sync line slot. The white RCA plug of the sync line is the sync signal output line; connect it to the BNC to RCA adapter cable. Insert the other end of the sync line into the AUX port behind the Nokov optical lens. Ensure a secure connection by firmly inserting the plug until it clicks into place (16.2.4.6).
Main Camera Synchronization: Insert the sync line into the AUX port at the back of the main camera.
Secondary Camera Synchronization: In scenarios involving the use of a digital force platform and digital electromyography, synchronization with a secondary camera is required. Use two sync lines: connect one sync line to link the main camera with the amplifier of the force platform, and connect the other sync line to link the secondary camera with the BNC to RCA adapter cable.
Open the XINGYING software and open the EMG configuration window in the third-party device menu bar. If the main camera synchronization scheme is used, check the "Cometa (Digital)" checkbox. If further synchronization is required, also check the "Digital Force Plate (USB), Cometa (Digital)" checkboxes (16.2.4.7). For the configuration instructions of the force plate, please refer to the above text for configuration.
Open the channel configuration window in the third-party device menu. Add analog channels based on the number of electromyography modules being used. Set the range for each channel (16.2.4.8).
Sampling Rate Setting: The Cometa electromyography supports a maximum sampling rate of 2000 samples per second. The sampling rate is calculated as Sampling Rate = Frame Rate x Multiplier. The XINGYING software defaults to a frame rate of 100 fps and a multiplier of 1. If necessary, you can make modifications in the device panel and force platform parameter settings window (16.2.4.9).
After completing the above configurations, click on the camera connection button at the bottom of the software. Click on Play, then click on the Analog Chart button in the toolbar to open the chart. Open the analog channel panel, check the checkboxes for the channels, and enable adaptation. By following these steps (16.2.4.10), you can view the real-time waveform and data of the electromyography module in the analog chart.
