Problems with fiber optic cables
Hi at all,
i had the following problems two days ago:
For use came a Mac Pro with a Triplehead2Go and some active DisplayPort to DVI adapters from ATI and a passive DisplayPort to DVI adapter from Apple. So far so good. With me in the studio all played flawlessly. (Of course, no fiber optic, DVI with normal cables)
As fiber optic cable following was used: http://www.kramerelectronics.com/products/model.asp?pid=783
The problem was that I could not send any signal to the projectors and preview monitors on the stage via the active and passive adapters nor with the Triplehead2 Go via that fiber optic cable. The MacPro and the Triplehead2Go had never identified a projector or monitor with this cable connected.
In my view, the adapters and also the Triplehead2Go should send the EDID data without the use of additional equipment via the fiber optic cable.
I always have a Lightware crosspoint for such problems with this and also helped. In this case, I have put all the outputs of the passive or active adapter and the Triplehead2Go on the inputs of the crosspoint. I have connected the transmitter of the fiber optic cable to the outputs of the crosspoint. I would use my Inputs and Outputs of the crosspoint rather for otherthings than for bug fixes.
Anyway, maybe someone knows the reason of this kind of problem, why such a fiber optic cable does not work directly on the adapters or the TripleHead2Go connected?
Another question would be, does someone has the Datapath X4 directly operated with such cables and gained some experience? Then I would buy this box immediately.
