Connector types for 1394a interface

The 1394a interface, also known as FireWire 400, primarily uses two types of connectors: the 6-pin and 4-pin connectors. The 6-pin connector is commonly found on devices and provides both power and data transfer capabilities, while the 4-pin connector is typically used in smaller devices like camcorders and does not supply power. Additionally, there are 9-pin connectors used in some applications, particularly for backward compatibility with 1394b interfaces.
