A method and device for transmitting data reliably to at least one item of equipment is provided, wherein: from its initial clock H1, an item of equipment generates at least one first clock H1U from a rising edge of the initial clock H1 with a frequency F1U and a second clock H1D from a falling edge of the initial clock H1, with a frequency F1D, the item of equipment: reads the received data using at least one first rising edge of H1U and one falling edge consecutive to the first rising edge of H1U, then reads the received data using a first rising edge of H1D and a falling edge consecutive to the first rising edge of H1D, the four clock edges used being consecutive by 2F1, decodes at least the four messages using an error-correcting code, when at least one decoded message is correct, it uses the information contained in this message to drive a device linked to said item of equipment.
