Abstract
An improved communication channel between two sites in which power for the second site is communicated via the cable from the first site's electrical source. Since the electrical source is used to create a higher voltage instead of power from the host apparatus at the first site, enhanced transmission is possible permitting the cable to extend in excess of one hundred fifty feet. Further, since the remote second site does not require any power at its location, it can operate in a wider range of applications and environments.
