No optical direct for Phantom Ultimate

[Yondu]

Hi, direct optical mode will not be available to Phantom Ultimate (actual products) via software update as you consider it for Phantom I because direct optical mode is hardware dependent. As far as I know latency on a pair of stereo Phantom Ultimate can be configured to 80ms. By default latency is 250ms. If your network proposes enough performance you can adjust latency to 80ms. Solo product latency is 55ms.
