Brief Description: Mounted the Grand Rapids Technologies (GRT) GPS RA
I mounted the Grand Rapids Technologies (GRT) GPS RAIM Module. This provides a dual GPS input via an RS-232 serial port for GPS Position Data to the GRT HX EFIS, GTX 327 Transponder, and ELT along with the Garmin 430W COM/NAV radio using a switch mounted on the dash to determine which GPS is in-use. The module has separate power, ground, and serial port input/output.
