I just picked up a new Standard Horizon HX851 (Handheld VHF/GPS) and GX2150 (VHF/AIS)
If you put the HX851 in the cradle, it has NMEA cables you can use. So I tried connecting it to my computer via DB9 female connector to USB-Serial cable and whenever I hook it up the strobe light starts blinking. I'm a computer guy so I know I got the computer side right, com port, 4800 8N1, etc.
So I tried hooking it up to the GX2150, which in theory I should be able to pass GPS from the handheld to the fixed mount, and the same thing happens, the strobe just starts blinking.
On the HX851 I turned on some of the NMEA outputs. Didn't help.
On the GX2150 I made sure it was set to low speed 4800.
On the HX851 green is common. On the PC I ran green to pin 5, on the GX2150 I ran green to green.
On the HX851 blue is NMEA Output. On the PC I ran blue to pin 2 or 3, didn't make a difference. On the GX2150 I ran blue to blue or grey, didn't make a difference.
I've already emailed Standard Horizon... but I'm impatient and it will bug me all day that I can't figure it out. If anybody can shed any light on this please do!

On your PC, try using a terminal emulation application, like Hyperterminal, attached to your serial port to see if you're getting the expected data stream from the NMEA output device. Another nice tool I found is a NMEA simulator for your PC, http://www.kagstrom.no

Thanks. I called support, the fix was this:
Radio Setup -> LED Setup -> Water Hazard LED -> Off
