Log in. Data transmission is possible in both directions: camera control, triggering, parameterisation is equally possible during operation. Officially specified are 4. The maximum transmission length strongly depends on the quality of the integrated bus components in camera and PC and the quality of the cable.

Longer distances require inline repeaters or FireWire hubs which are connected in between. In theory, up to 63 devices can operated on one bus, 16 of which can be cameras. The term "daisy chain" refers to a wiring pattern in which one device is connected to the following one; i.

IEEE devices usually have two connection in order that the mentioned chaining can be realised. Cable lengths can be maximised in this way. Practical experience with IEEE camera systems in industrial facilities, however, reveals that up to 3 cameras on one bus always work in a stable and reasonable manner, yet interferences, problems with the overall cable length, etc.

Therefore use rather one or several dual FireWire cards if you want to operate more cameras, particularly synchronously and with high load. The cable has been changed, now it has nine conductors and a new plug, but a backwards compatibility to a was made possible using bilingual controller chips.

A FireWire b interface can operate FireWire a devices, too, using suitable adapter cables. FireWire b allows for the use of different cable materials, e. They provide the most speed with extra features like two-way power and multi-monitor support. In addition, both technologies have already been adopted by many major PC manufactures.
