I am trying to setup a QK-A2K032 with a Standard Horizon GX2200. I just want to be able to view AIS data on a tablet running Navionics Boat App. I can connect the tablet to the QK-A2K032 and it shows up as a paired device. On the QK-A2K032, the only light that ever flashes is the red power light. I have tried hooking it up 4 different ways. Two configurations were 38400 baud and the other two are 4800 baud. Below are the wiring configurations I have tried. What am I doing wrong?

23/11/2021 at 1:46 pm #17938AnonymousI’m away from the boat for a week. I’ll have to get back to you.
27/11/2021 at 3:20 pm #17970AnonymousI’m heading back tomorrow. What firmware should it be and what wiring scheme should I use?
28/11/2021 at 11:19 pm #17982AnonymousThe firmware is V2.10.210326
29/11/2021 at 11:51 pm #18008AnonymousMy slip neighbor just came over with a portable AIS receiver. We hooked it up and nothing. The power light blinks, but the green lights on the QK-A2K032 never blink. That is the same that I am getting when the GX2200 is hooked up. Also, my neighbor is a retired NASA engineer, so I feel pretty confident in his diagnostic skills compared to mine.
30/11/2021 at 4:20 pm #18015AnonymousHi John, We recreated this setup in our lab and observed that by connecting the two devices in the following way will resolve the communication issue between them:
GX2200E A032
(GRAY) NMEA OUT+ to (BLACK) IN B –
(BROWN) NMEA OUT- to (GRAY) IN A +
Please be aware that both the GX2200E’s NMEA OUT baud rate and A032’s NMEA IN baud rate has to be set to 34800 bps.
