InLink is a complete HART protocol modem that modulates logic level 1200 BAUD serial data to a HART loop, and demodulates received HART data providing a 1200 BAUD serial bit stream. InLink interfaces to standard 3.3 volt logic.  InLink includes loop transformer isolation and AC capacitor coupling, eliminating loop connection polarity and grounding  issues.  Adding only RS232 transceivers and a power supply make a complete RS232 to HART interface.  The InLink small package size simplifies integration into your design.
