Figure 20: Meter and R-A fields
The Meter and R-A fields are described in figure 21 but the following additions apply
when adding/updating a meter:
● Set meter PrimA = 0xFF to avoid updating it.
● Set all 16 bytes of meter key to 0xFF to avoid updating it.
• Meter lock flag:
o 0x00 = Meter is not locked in meter list.
o 0x01 = Meter is locked (erase protected in continuous installation FIFO mode)
o 0xFF = Avoid updating meter lock flag (keep current settings)
● Set all R-A fields (8bytes) to 0xFF if no separate radio adapter is used.
