VPRS App

Updated on Mar 4, 2026

 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.
