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)

Cuando se recibe un paquete de un dispositivo externo que tiene un valor válido, se envía un paquete de éxito. De lo contrario se envía un paquete de error.

Una paquete de error se envía si:

Se ha recibido un paquete cuya longitud no sea igual a 7 bytes.

El valor de la cabecera del paquete de 2 bytes no es igual a 0x08, 0x22.

La suma de comprobación no es correcta.
