Paul,
?
Today I've been investigating the Bad Checksum and Exception errors, which I posted earlier.
As I got another MeLE Quieter 4C for my another Gemini-2, I setup the exactly the same configuration as before.? This time the Gemini-2 unit and mini-PC were different, but the same Ethernet cable.??Under the same environment, where TheSkyX, SGPro and PHD2 were connected to the unit and running, I got a lot of communications error after the first stage.? However after I power cycled the unit several times, strangely the errors were gone. ? When I looked into the ASCOM.Gemini Telescope .NET log file, there were a lot of Bad Checksum and Exception errors during the period when the communications errors occurred.? This was very intermittent at that time, and there were no errors, very stable for many hours.
So I became confused.? After all I asked ChatGPT about Bad Checksum, in particular, relating to the direct Ethernet connection.? ChatGPT suggested to use a cross-over cable instead of a standard one, which I have used after I introduced mini-PCs.? So I took a cross-over cable, which was used to connect Gemini-2 to ThinkPad X230/X270 in the past.? Until this evening I carried out the test for 5 hours.? According to the log, there were no errors.? I don't know this is exactly the cause or not.? I will test this configuration under the real sky if the weather becomes cooperative.
