1 Communication with BushingGard using computer USB port There are two ways of communication with BushingGard through computer USB port: Direct communication between computer USB port and BushingGard USB port allows for full scale communication from BushingGard software and Configurator software. BushingGard firmware can t be reprogrammed through that connection. Communication through RS485-USB adapter between computer USB port and RS485 port on BushingGard allows for all regular communications plus firmware reprogramming in BushingGard.
