10.1 Compatibility mode of NMT53x and NMT81
NMT81 has different HART device codes depending on the measurement conditions. The
NMT81 can be switched to a NMT53x compatibility mode in which it operates as an
NMT53x but limited to basic functions. When the NMT53x mode is selected, the device
can be connected to FieldCare by switching to the NMT81 mode by using the dip switch.
