..."two new cameras, the XCD-V50 B&W model and XCD-V50CR color model, both featuring IEEE 1394.b compliant interfaces allowing longer cable runs, daisy-chaining of multiple cameras on a single cable run, faster frame rates and backward compatibility with most computers that can interface to existing IEEE 1394 technology.
