Code examples

UsbRelayManager manager = NativeUsbRelayManager.getInstance();

try {
   //init manager
   manager.relayInit();
   //enumerate devices 
   UsbRelayDeviceInfo[] devices = manager.deviceEnumerate();

   for (int i = 0; i < devices.length; i++) {
      UsbRelayDeviceInfo usbRelayDeviceInfo = devices[i];
      //retrieve device handler            
      UsbRelayDeviceHandler handler = manager.deviceOpen(usbRelayDeviceInfo.getSerialNumber());
      //change relay status
      //turning on the relay, index - channel number
      //Get device status
      UsbRelayStatus[] statuses = manager.getStatus(usbRelayDeviceInfo.getSerialNumber(), handler);
      //close relay
      manager.closeRelay(handler);
   }
} catch (UsbRelayException ex) {
      //catch exceptions
} finally {
      //close manager
      manager.relayExit();
}
