Using the General Purpose Interface
The RBMS Plus is based on PBT’s GP series of general purpose power supply transponders with a special application
module and firmware to perform the RBMS Plus functionality. The GP interface can be used to monitor and control
auxiliary equipment if the interface between the GP and the monitored/controlled equipment is properly designed.
This section discusses how the GP web interface screens relate to available GP input and output points, as well as
electrical specifications for interfacing those points to the target equipment. Please refer to the picture below that
shows the locations of the interface connection points on the GP’s front panel.
