{"bus_datatype":"uint32","bus_address":"4/2/12","address":43418,"value_nan":[65472,0],"type":"register","read_count": 1,"value_multiplier":1,"units":"h","name":"15EP_OP","datatype":"uint32"},
{"bus_datatype":"uint32","bus_address":"4/2/6","address":43420,"value_nan":[65472,0],"type":"register","read_count": 1,"value_multiplier":1,"units":"h","name":"14EP_OP","datatype":"uint32"},
