The new PowerBox 3 (PB3) has been designed to be fully compatible with existing VMU S2 Systems, however they can be used on their own with the optional USB cable sold on this website. Once you connect the powerbox to your computer, you can use any terminal program set to 9600,N,8,1 and interact with the PB3 via its inbuild management console. Please refer to the PB3 manual for command summary and programming examples.
PB3 - Functional Block Diagram
