Do I need to use the H3/H4 caps to experience the full benefits of the VisiFerm RS485?

VisiFerm RS485 is compatible with the H0/H2/H3/H4 caps. The sensor electronics will provide a 50% longer lifespan with any of the ODO caps. The H3/H4 caps are required to decrease the number of VisiFerm RS485 calibrations by 80%.
