Device for controlling point-to-point communication between a module and transmission bus

Device for controlling point-to-point communication between a module (10) and a transmission bus (22), the device comprising a printed circuit (20) which carries the transmission bus (22) and which comprises a connection element (21) intended to connect the module (10) to the transmission bus (22), characterized in that the printed circuit (20) comprises:

• a communication control unit (23) disposed between the transmission bus (22) and the connection element (21), the said unit (23) comprising at least one bidirectional communication assembly (231, 232) furnished with unidirectional communication three-state logic gates (24E, 24R) disposed mutually head-to-tail,
• a logic control circuit (30) for the said logic gates (24E, 24R).
