I noticed when I powered it up that the TX light blinked whether there was a PC connected or not, so I guess the PC doesn’t need to poll it for a response. I assume you have the voltage set correctly? There are two options, one regulated and the other not. I also assume you have tried POR a few times. Lastly, pretty basic, but it might not transmit without an antenna. But something doesn’t make sense and that is the RX led flashing. I don’t want to imply you have the RX and TX mixed up, but I just checked mine and after POR, from the left, I have PPS, RX, TX and Power with the PPS and TX blinking. This is without any PC code running. I would start up Lady Heather and see what happens. Then you should see RX followed by TX after PPS with Green power on solid. The PPS pulse is 198us wide on mine. Also, I might have an older version, I think it is a 2002 series.

>> Can you please check your PPS to see if you get a signal when in that other mode (where it needs at least one sat locked)?
