The response includes the parameters activated in the data messages. 
See Chapter 8 Sensor and Data Message Settings, on page 127.
The response format:
$WIXDR,a1,x.x1,u1,c--c1, ...  ... ..an,x.xn,un,c--cn*hh<cr><lf>
NOTE
The parameter order in the output is as shown in the parameter 
selection setting field. See Chapter 8 Sensor and Data Message 
Settings, on page 127.
