Fred, The light bulb is starting to glow... So if I understand correctly, you cut the USB connector off of the GTRANS cable, and opened up the coating on the circuit board to give you access to 3 connections. +5v, Ground, and Data. Is that correct?
The Data out from the GTRANS comes out of the DB-9 port 1. Ground is shared with the existing port. This basically means the only part of the GTRANS cable in use is the actual circuit board. The USB and the radio plug are "discarded" for future use? That setup should allow for the Garmin Protocal coming into the OT2m for positioning will also be outputted as NMEA. Now, what would happen if the signal coming into port 2 was already NMEA? I would assume the GTRANS would do nothing then, correct? I also like the idea on the LCD Display. That was something I forgot about. That would be something neat to place above the radio on my dash, or in my APRS Kit that will hold my OT2m and Radio, so I know I am decoding valid data. Where did you purchase the LCD Display from? I see three links on the Wiki, did you use one of those? Additionally, I am going to add a switch to allow me to change profiles on the fly. I would also like the switch to have a 'momentary' position so I can key the radio if I needed to test for VSWR or anything like that. I love how a simple project of putting a tracker in my vehicle has turned into a snowball picking up speed! What a great hobby :) 73 & Thanks for the help Phil / w2lie
