I have an issue with power led indicator. it always off during the operation. the attached photos contain 2 encoders, one has the problem compared with the other.
I would recommend sending an email to info@epiphan.com for further troubleshooting. If you are noticing any other issues with your Pearl-2 unit please notify the details as well in the email. We can also provide you with the most recent firmware version as well, as your unit is running a 2017 firmware version.
