i think i need a gv net card, but not sure. the spectra III has a TX+, TX-, RX+, RX- port on it. the schematic for the gv net card has RS 485+ and RS 485- ports on it. i'm confused on this. are they compatible?
I'd be using a cat 5E cable using 1 of the 4 pair to BNC baluns for video, and could use the other 3 pair for PTZ control.
i haven't bought a gv net card yet. wanted to know if this is the way to go.
any help would be greatly appreciated.
thanx in advance...
