Hello mtkrane
Sorry, I didn't look into the download page. Download the version for XPort, this is the Lantronix device inbuilt in the easy209-SE. But I think, it's not critical, I use a version 3.6 and it's doing well.
The update to easy OPC server version v1.10 isn't available yet, but will be published shortly. If you would like to PM me your email address, I'll give you a hint, as soon as the update is available.
The attached zip file contains snap shots from the DeviceInstallers web interface with the working parameters.
Best regards and good luck
Bernhard
