3. When “W” command is given, a reset is necessary to initiate the command.
4. “X” in bit pattern information means the bit is not related to that parameter.
5. Each byte consists of 8 bits.
6. Each byte consists of 2 nibbles; Most Significant Nibble (MSN) and Least Significant Nibble (LSN)

10.1 Lockout

Bytes

“R” or “W” followed by “01”, “02”, “03”, or “04” send to EEPROM or receive from EEPROM the 8 bits of each of
the four lockout bytes.

For example, if you want to make L2 CNF be “01011010”, the hex equivalent is “5A”, so the computer sends
“*15W025A”.

The meter would echo the command with “15W02” if “BUS.3=1”.

Below is the bit pattern corresponding to the lockout bytes.

NOTE: Each Lockout is one byte (8 bits) where:

L1C.1 is bit 0 of Lockout #1
L1C.8 is bit 7 of Lockout #1


Each item on the left will lock out following item on the right.
