EQMOD comm errors when I connect ZWO ASI 533

[jon s paul]

Hi All I am new to this site and would very much like some help. I have a HEQ5 that I control through a  Pegasus FTDI cable (no hand controller in the system)  with a Beelink mini pc running an I8 intel processor and 16 gb ram on windows 10 pro. The PC has 4 USB3 and usb C 3.1 ports and connects to the mount without any problems through ASCOM and EQMOD. Tracking and sync are fine. I have my pc and eqmod driver set to 9600 baud rate. the EQMOD time out is set to 2000 and retry rate at 2. Everything is fine and the Message center window in EQMOD has no errors at all. When I connect my ZWO ASI 533 camera the problems start.  I start getting comm errors in the EQMOD message center window such as Comm err ER=8702832, ED=16777216, MSR=144, MSD=160, RA and Dec motor stopped, . eventualy the mount disconnects from Cartes du Ciel and EQMOD. I have tried reinstalling the ASI camera driver and the ASI ASCOM driver. Also I have reinstalled ASCOM and EQMOD. and the driver for the FTDI usb cable. I am at a loss what to try next.

After weeks of problems I have finally solved this issue. one of my 240v to 12v power supplies was working but must be faulty as it was causing all the communication errors.
