n1= 1 gives the setting of parameter 1, etc. The parameter names are listed in “Serial
interface set-up” under Summary of Parameter Settings on page 81.
n1 = 0 gives a response where the first two bytes specifies the length of data to come, and
then follows a block of data for all parameters in the temporary setup.
