Hello
I found spc900nc and wanted to use it as a guide camera with astroberry 2.0.3, no problem with image but I can't make it long with FT232RL converter, can't send RTS / DTR signal. Astroberry mounts usb0-OnStep and usb1-Lx ports, but no response to the port. SPC900Nc-LX works fine in WIN10 and PHD2 and can control RTS / DTR. Anyone had such a case or know what the problem is? greetings

The SPC900 does not do long exposure, unless it has had a special long exposure modification, if it has it will have two cables on it and will then work, I would guess that your camera has not had this mod, so it won’t work in this mode....

It is converted to lx mod sc2 and rs232 works fine under win10 and does not want to work on linux (no RTS / DTR control) astroberry end ubuntu 18.04

Ah, ok, then this is a question for @knro
