What line is needed to connect the back of the number?

Hello, the back of the number is divided into fire line and trigger line.

Firewire: It is the wire from the back to the computer.

Trigger line: it is the line connecting the lens and the back.

If it is an old digital back, it is usually taken by connecting a computer with firewire. There are two kinds of firewire interfaces, one is 400 ports and the other is 800 ports. When connecting the computer at the back, see clearly what the port is and what port line to use.

The trigger wire is used in the fuselage of Hasselblad machinery, mainly to trigger the back work, but it is not needed in the back of Hasselblad CFV, such as Kangtaishi 645, Mamiya 645 and Hasselblad H series fuselage.
