VPRS Display App

The VBOX Precision Ranging System (VPRS) App can be used to display the outputted distance measurement from a Beacon to a Rover when using the VBOX Precision Ranging System. Ensure the Rover unit is connected to VBOX Touch using an RLCAB120 cable from the 'Power/CAN Data' port on the Rover to a 'CAN / SERIAL' port on VBOX Touch.


The app is available to download here, instructions on how to install can be found here.

The app consist of two main screens; the range screen and the results screen which can be navigated between by selecting the Forward Forward Arrow.png or Back Backwards arrow.png arrows on the bottom right of the screen, or by swiping the screen left or right.
