I have checked the communications with my telescope by purchasing a Startech USB to Serial adapter (ICUSB232V2) and running a program called PuTTY on my Windows 10 operating system to allow me to hand input the codes to communicate with the telescope. I tested each of the commands available for the Magellan 2 and they all worked fine and gave back the expected return data. I then went back to the Skyfi 3 and tried it using LX200 Classic for the telescope setup (no Magellan 2 setup available, command codes the same but much fewer). However, I still get the dialog that says it can't communicate with the telescope. One thing that may be a problem is that every time I set the baud rate at 300 and double check it, then I go to try to connect to the telescope, and when I go back to see if the baud rate is still 300 I find that is back at 9600. I don't know if this could be the problem. I really want to get this working but I can take it no further without technical assistance. I would also like to use my Startech adapter but I doubt if you have the drivers installed to operate it. One other thing if anyone else reads this is that I originally had problems with the cable wiring. In all their wisdom Meade made the RJ11 pin-outs in the order 1 4 2 5 3 6 instead of the standard telephone wiring setup of 1 2 3 4 5 6. My original manual was confusing but when I loaded a more recent version of it everything became clear.
Why Does My Meade Magellan 2 Communicates With A Computer But Not With SkySafari 6 Pro + Skyfi 3?
