You will be using the IMPlug software provided by Inmediata to securely upload the claim files created by Open Dental. In the IMPlug - Configuration window, click the Integration Settings tab and fill it out like below. You will need to create the Reports folder and the Claims folder in the process.
You do not need to put anything in the Outbound History box because Open Dental already keeps a history in Claims\Archive.
Import of ERA is fairly automated. The Inmediata Inbound path should be set the same as the Report Path on the Edit Clearinghouse window. Then the 835s should import automatically each time a claim is sent, or manually when Get Reports is clicked on the Insurance Claims window.
