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) (Decimal)

CS [1 Byte]: Suma de comprobación (el segundo complemento de la suma de todos los valores, excepto el valor CS)

2.Estructura del paquete de respuesta [3 bytes]

1.Éxito

0x03

2.Error

0x0C

0xF1

0x030x0C0xFF

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.

Detección de error por un dispositivo externo

Un dispositivo externo califica el paquete como error si no recibe un paquete de éxito en 100 ms.
