I have a triple imaging rig currently using 3 separate RPi boards. The imaging cameras are an ASI 294MMPro connected to an RPi 4B running Astroberry Server and two ASI 1600MM-Cool cameras on separate RPi 3B boards and the earlier indiserver. The RPi 4B also runs the mount and a guide camera. This system is accessed using 3 instances of Terminal with SSH and 3 instances of KStars/Ekos running on my tower system with Linux Mint indoors.I would like to reduce the remote electronics and wondered if I could run 3 instances of Ekos in Astroberry Server. IOW use one RPi 4 only and get rid of the RPi 3Bs. The original reason for using separate RPi boards was that Ekos was unable to distinguish between the two ASI 1600MM cameras - they come up with the same ID. I now wonder if separate instances of Ekos could access different USB ports and avoid the ID contention.Any information and suggestions gratefully received.
