Section 3.3.2.2 - Connection Errors
If you encounter problems connecting to your rotator, first check the integrity of your Pyxis' USB or Ethernet, and power connections.
Next, verify that the COM Port setting on the Setup menu of the control program matches the COM port that the rotator is plugged into. For Ethernet connections make sure that you are on the same sub-net and that your firewall does not block connections.
Finally, check for any updated versions of the software on the Optec website and reboot your computer.
If this does not solve the problem, it is likely that the problem is not one that may be easily solved. Therefore, it may be best for you to simply contact Optec directly if you encounter a connection error.
