A TTL 5v signal is required for the trigger line of a 1407. As long as you have good cabling and are able to keep your signal clean, you should be able to transmit a trigger signal for a significant distance.
Take a look at the HL Triggered Snap.vi example under the following directory:
C:\Program Files\National Instruments\LabVIEW 7.1\examples\IMAQ\IMAQ Signal IO.llb
Good luck with your project!
