Command: @ 0 0 R X 0 0 0 0 FCS * CR
Response: @ 0 0 R X 0 0 0 1 0 0 FCS * CR
The command includes a total of 13 characters (FCS would be two; CR, one)
and the response includes 15. Placing 13 and 15 into the above equation pro-
duces the following:
(13 characters x 11 bits/character)/9.6 bits/ms + 50 ms + 500 ms =
570 ms (approximate) + (15 characters x 11 bits/character)/9.6 bits/ms
= 13 x 11/9.6 + 50 + 500 + 15 x 11/9.6 ms
= 583 ms (approximate)

The measured temperature would thus be returned to the host computer a maxi-
mum of 683 ms (15 ms + 668 ms) or 583 ms (15 ms + 568 ms) after the host
computer started transmitting the read command. The measured temperature
that was returned would be the one that was current 668 ms or 568 ms before
the response was received.
