Issued IDs can be displayed in hexadecimals. However, ID 0 must be displayed as 0xFF.
All communications take place in hexadecimals. The checksum is calculated by adding up all values
except the header. If a checksum adds up to be more than 2 digits as shown below
(11+FF+01+01=112), the first digit is removed.
