Check sum becomes OK'ed when the lower
8-bit of the sum of the received absolute data
(15 characters) is 0.
Caution
• Allow 50 ms or longer interval for axis switching when you want to
capture multiple axes data.
• It is recommended for you to repeat the above communication more
than 2 times to confirm the absolute data coincide, in order to avoid
mis-operation due to unexpected noise.
