RT Plugin Xio
Overview
The Xio Plugin is only used in Visual3D Server™; it connects to software for x-IMUs.
It will not work with Visual3D Professional.
Plugin Interface
The “Plugin Help” button leads to this web page should you need to reference this page in the future.
The “About Plugin” button has details on the plugin being used including version, release date, copy right, support contact information and the hardware SDK version.
Frame Info
 |
Current frame The current frame number on the top left hand side on the screen (where it is currently blank) keeps a count of the current frame which is assigned by the hardware or software system.
Missed frames The missed frames number is on the bottom left (where it is currently blank). Whenever there is a gap in frames sent by the hardware of software system a blank frame is inserted. The dropped frames count keeps a record of both the number of frames which are blank.
Hardware time The hardware time number is on the top, in the centre (where it is currently blank). This time stamp is created by the hardware being used and is how long, in milliseconds, the hardware has been running.
Server time The server time number is on the bottom, in the centre (where it is currently blank). This time stamp is created by the server and is how long, in milliseconds, it has been connected to the hardware or software which is streaming to it.
Hardware latency The hardware latency is on the top right hand side (where it is currently blank). This indicated the delay created by the hardware system.
Server latency The hardware latency is on the top right hand side (where it is currently blank). This indicates any delay introduced by the server.
Hardware

Data Rate
This is the rate in Hz which the data is collected. The options are: 32, 64, 128, 256 and 512.
Fusion Algorithm
The fusion algorithm options are IMU (Inertial Measurement Unit) and AHRS (Attitude and Heading Reference System). The IMU algorithm makes use of data from gyroscopes and accelerometers. The AHRS algorithm also makes use of tri-axis magnetometer data, allowing for measurement of the devices orientation relative to the earth's magnetic field.
Beta Gain
The beta gain changes the relative usage of the accelerometer and gyroscope in the fusion algorithm. The beta gains counter should be set between 0 and 10. The number in the counter is ten times the value of the beta gain implemented. So a counter value of 1 will result in a 0.1 beta gain, a counter value of 7 will result in a beta gain of 0.7, etc..
Number of Sensors & Serial Port
The number of sensors tells Visual3DServer how many IMUs to look for. The minimum number that can be entered is 1 and the maximum is 12. The sensors can be selected in the drop down menu and assigned a Serial Port using the serial port counter. Once a serial port is assigned to a sensor it will it will appear next to the sensor number in the drop down menu. The Serial Port numbers range from 0 to 99.
Trigger Threshold
The Trigger Threshold ranges from -20 to 20. Changing the Trigger Threshold results in a voltage change on the “AX0” analog input pin of the sensor unit that will create an input spike in the data streams for later synchronization of multiple sensors.
Table
The Table at the bottom of the hardware tab provides a summary of the Sensors connected as well at their Port number and the Segments with which they are associated.
Signals
 | The table in the signals tab holds all of the numerical data from various sources which is being streamed to the program. This data may include, but is not limited to, marker co-ordinates, force data, EMG readings, accelerometer data, etc. The first column entitled “Label” has the number or name which has been assigned to the source of the data. The following four columns are all entitled “Value”; they have the numerical data associated with the source. For markers it is the x, y, and z, coordinates and then the residual. For force data there is only one value associated, which is the magnitude of the force. |
 | The signals graph allows you to see a graphical representation of the values in the table. Selecting one of the rows in the table will cause the graph to record the values in real time. The x axis has the frame numbers and the y axis has the numbers in the value column. If more than one column has data there will be multiple lines drawn. The graph uses the MKS system of units. |
C3D Params
 | When this tab is viewed in Visual3D Server it gives additional details regarding the data that is being collected by the server and streamed to a client. This allows you to check details such as force plate types and locations. The top table contains a list of the parameters and their subsections. By expanding the parameters and selecting one of the subsections the data from the subsection will be presented in the table at the bottom of the tab. |
3D View
The right hand side of the screen provides a real-time 3D graphical representation of the data being streamed.
Save 3D View
This button allows you to save what is currently being displayed in the 3D view graphics area. The image can be saved in a number of standard formats, such as .bmp, .ico, .jpeg, .jpg, .pbm, .pgm, .png, .ppm, .tif, .tiff, .wbmp, .xbm, or .xpm. This function is ideal for producing graphics for papers or presentations. Saved images can be edited with 3rd party graphics programs if needed.
Copy 3D View to clipboard
This button allows you to copy what is currently being displayed in the 3D view graphics area to the clipboard. This allows you to paste the image into any program that supports copy and paste. This is useful for working with presentation or graphics editing software.
Reset camera 3D View
This button brings the 3D viewer back to it's beginning position. You may find that having used the rotation, translation, and zooming capabilities of the 3D view you have lost track of where you are in the graphics, which can make returning to a proper view of your data challenging. The reset view button removes this frustration and reorients you.
3D View Preferences
This button allows you to change how the graphics that are presented to you. Changes happen in real time. At the bottom is the “Restore Defaults” button which resets all of the options to their standard setting.
