NOTES:
• This sets up the window for retrieval; now we can start retrieving the records.
• As noted above, we compute the records per window as 246\18 = 13.66, which is
rounded to 13 records per window. This allows the minimum number of requests to
be made to the meter, which increases retrieval speed.

13. Since the window is 246 bytes, and the record
is 18 bytes, 246\18 = 13.66, which means that
13 records evenly fit into a single window. This is
234 bytes, which means later on, we only need to
read 234 bytes (117 registers) of the window to
retrieve the records.
1. We are using auto-increment (so not 0), but
not function code 0x23.
0 (ignore)
0, start at the first record.
