4. The EFB (WiFi, iPad, FlttPlanGo) works great. However so far have not seen the data or WX on the EFIS yet (but that may be an EFIS filter thing). Have a call into GRT. My questions are generic for my education as a newbie.... (Not I know I will not get weather due to range from towers, but have lots of traffic I see on EFB, grated a lot of that is 7K to 39K feet above. That may be the issue, BUT MY QUESTIONS ARE AS FOLLOWS:
   Q5. I tried the STRATUX style CP2102 Chip adapter first. No joy. I was told no patch was needed and it would auto configure. I bought an adapter that looks IDENTICAL to one on Stratux Store (amazon). Amazon store was sold out. Is there something special about the CP2102 USB to Serial adapter Stratux Store sells that is "PLUG and PLAY"?

Q6. TRENDnet TU-S9 USB to Serial adapter seems to work and EFIS sees it... I had to upload a PATCH from GRT and loaded it on the STRATUX via WiFi. I see data counter in settings page of EFIS. Is there a way to increase the BAUD RATE in Stratux or doesit default to a setting? (Note GRT has setting set to 115,200 baud and selected to ADS-B sentence. The GRT has 12 high speed ports.)

Note I recall the TS-S9 has CP2303 chip. The CP2102 chip board has 3 dip switches, so it can be used for TTL as well as RS232/485. I guess not all USB to RS232 converters are thee same....

Q7. Can someone explain how those "patches" work? I assume it is an addition to the OS to help it know how to handle something, like a serial port. My question CAN I REMOVE a patch I installed? Can I see the patches I installed?
