If you need to know which hardware variant your VBOX 3i unit is, you can easily find out by locating the serial label on the side or bottom of the unit:
This label contains information about the VBOX unit, such as product code, serial number, power specifications and compliance and waste symbols.
The VBOX 3i units will have a product code, for example, VB3i-V5 (product range and hardware version) and feature markers, such as D for Dual Antenna and RTK for RTK-enabled. If the feature marker has a filled, black circle on the left your unit has this feature. If the circle is not filled, your unit does not have this feature.
Note: Our RTK units will always have two antennas but not all units with two antennas will be RTK enabled.
