 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.
E.g. Power On & ID=0
Header Command ID Data length Data 1 Checksum
0xAA 0x11 1 "Power"
Header Command ID Data length Data 1 12
0xAA 0x11 1 1
 To control all devices connected by a serial cable simultaneously irrespective of IDs, set the ID
as "0xFE" and transmit commands. Commands will be executed by each device but ACK will not
respond.
