Management Commands
The following section details the operation of each
management commands available in the eIMR+ de-
vice. In all cases, the individual bits in each command
are shown with the most-significant bit (bit 7) on the left
and the least-significant bit (bit 0) on the right. Table 5
and Table 6 show a summary of default states and a
summary of management commands, respectively.
Note: Data is transmitted and received on the serial
data lines least-significant bit first and most-significant
bit last.
