摘要：
Serial connection for connecting a listener to at least two drivers (101) through a single serial bus (40) and a common connection (50) carrying an external trigger signal, wherein each driver comprises:
• a first receiver transmitter (5) of the FIFO type, connected in between the serial bus and a data transmitter (3) connected to data generation means (20),
• a high impedance output control (8) connected to the first receiver transmitter (5), configured to not allow data through unless a command is received from a toggle signal transmitter (7),
• a timer (10) connected between the toggle signal transmitter (7) and the high impedance output control (8), configured to allow the command from the toggle signal transmitter (7) to go through after lapsing of a predetermined duration starting as an external trigger event happens, the external trigger event being based on the external trigger signal, the predetermined duration being different for each driver
• a data latch (11) connected between the data transmitter (3) and the first receiver transmitter (5), configured to allow the data through, upon detecting the external trigger event.
