•Un paquete de órdenes consta de 7 bytes en total.

•Los dos bytes 0x08 y 0x22 indican que el paquete es de comunicación serie.

•Los siguientes 4 bytes representan una orden preestablecida que el usuario puede definir.

•El último byte es la suma de comprobación que verifica la validez del paquete actual.

•Cabecera [2 bytes]: Valores predefinidos establecidos como 0x08 y 0x22.

•Cmd1 [1 Byte]: El primer valor del código definido en la lista de órdenes (hexadecimal)

•Cmd2 [1 Byte]: El segundo valor del código definido en la lista de órdenes (hexadecimal)

•Cmd3 [1 Byte]: El tercer valor del código definido en la lista de órdenes (hexadecimal)

•Value [1 Byte]: Parámetro de entrada para la orden (predeterminado: 0) (hexadecimal)
