9.3.1.2.4 Memory Read Response (Mxx)
Sends the data stored in memory location xx. The EEPROM memory
location contains the unit setup info, and sometimes has plot data from a
single sweep saved by the user. The response from the unit is shown in the
table below. Note that the response string is contained in the first column,
and is sent as a continuous string. The string has been subdivided in the
table for clarity. The format of the setup data is identical to the S000
response but with an S001 header instead of S000. The string of measured
data follows the setup data. The format of the measured data is always
resistance and reactance (D101- see measured data response above). This
command sends the entire contents of the memory location; the software
must determine the valid data points from the setup data (lower and upper
valid data indices). Data that is not valid is garbage and should be tossed
out.

9.3.2 Unit Setup
There are several pieces of information that can configure the Bravo MRI II
unit. Information such as sweep width, center frequency and data format can
be altered individually. Other setup information must be sent in a block of
data that contains the entire setup information for the unit. This setup
information may be read from the unit (to establish current settings) or sent to
the unit to change the units operation.
