Posi Stage Net

PosiStageNet (PSN) is an open protocol for streaming 3D positioning of objects on stage developed by VYV and Ma Lighting. http://www.posistage.net/ PSN is a network based protocol that reports the position, velocity and acceleration of multiple objects.

PSN uses an Automation mapping.

• Allow Learn Input: If enabled, the input can be used to automatically assign to a mapping with the learn button. It is advisable to disable allow learn input on sources that are constantly sending data as it will interfere with other sources associating.
• Create Enable Pin: Creates a new pin (Bool) to allow the controller to be turned on or off.
• Use Custom Pin Name: Allows user to name enable Pin.
• Network Interface: Choose which adaptor to use for receiving PSN data
• Listen Port: Choose which network port to receive on, must match the settings of the sender.
• Update Frequency: Sets how often data is sent from Multicontroller. This essentially sets the frequency of interpolation. It is recommended to set this to the output video frequency. (50 or 60Hz usually).
• Axis Interpolations: As the data refresh rate from most encoders is much slower than the output frame rate, it is often desirable to ‘smooth’ the movement. There are two methods for smoothing automation data in Hippotizer: Polynomial and Slew.
• Polynomial looks at a set of received values defined by the sample time, and attempts to find an equation to approximate them. Using this equation, it then tries to predict what values will come in next based on the look ahead time setting. The complexity of the equation is its Poly Order; an order of 1 would be a static number, 2 a straight line and 3 a curved line for example. In general, lower Poly Order produces better results.
• Slew is a simple interpolation: it takes data across it’s sample time and creates data points in-between.
  Both interpolation methods must introduce delay in order to function and may cause objects in Hippotizer to disagree with the real world, especially when changing speed.
