The MB0414C Coupler
This Coupler has been replaced by the G3 Coupler.
The Coupler powers the Rooftop Antenna, obtains the reference phase measurement from a 120/240V wall outlet, and sends GPS and reference phase data to the PC. Two serial port outlets allow 2 separate PCs to receive the data. Status lights on the Coupler unit are provided to confirm that it is operating properly.
