I am trying to get my Razor/V16 combo connected up to my new G3X Touch and I am having an issue. I have checked the wiring and it is all ok and I even updated the firmware in the Razor through the same wiring and that went fine.

The issue I am having is if I choose SL40 emulation then I can set the standby freq but no flip flop. If I choose GTR200 or GTR 225 then it won't even set the standby freq and it shows that the active freq is receiving constantly. What else can I check.

Thanks,
Eric

What is the age of your Razor? There has been an update or two to the unit for better support w/ Garmin RS-232.

You're selecting Garmin VHF COM and not Garmin VHF NAVCOM on the G3X, right?

I bought the Razor last year and just updated to the latest firmware yesterday with no change.

Garmin VHF COM is selected.

Do you have any other COM radios in your G3X System?

Nope, just the Razor/V16 combo

In looking at the serial output of the Razor I see why the G3X Touch is always showing RX on the active freq. The Razor is outputting $PGRMC01JTGFR08300=9<0D><0A> and for the GTR 200 protocol the R should be I is nothing is being received.

I don't currently have a way to capture the communication between the Razor and the G3X Touch so I don't have any idea why I can't set the freq in GTR 200 emulation or why I can't do the flip/flop.

From the GTR 200 manual

a .......................Transceiver status:
I = Intercom (no other status applicable)
R = Normal receive M = Monitor selected T = Transmit enable S = Stuck mic
F = Comm failure

Eric

Anyone have any ideas?

Is anyone using the Razor and V16 with the G3X Touch? If so can you toggle the flip/flop by touching the active freq on the G3X?
