Line Transmit

A slightly more compact version of the MBHP Line Driver Transmitter.

Schematic

MBHP Transmitter.

The two obvious differences are the J3 jumper (disconnects +5V from being sent) and the addition of a 100mil header. This way a DB-25 (or something else?) with ribbon cable mounting could be positioned off-board and wired to the line driver with an IDC.
