7.1.5 Scale Information Command Response
The ‘I’ and ‘N’ commands are used together to get all of the scale information data. The
‘I’ command will always return the 1st response below. The ‘N’ command must be sent
multiple times to get the 2nd, 3rd, 4th, 5th, and 6th responses. Once the 6th response
is received, the next ‘N’ command will return an Unrecognized Command Response.
At this point you would have to send another ‘I’ command to get the 1st response again.
