Technical Details

The command line arguments will be similar to this:

-l shared -p shared -pid [ChartNumber] server 1200


-l username -p password -pid [ChartNumber] servername 1200

In the first example, the username and password are both shared. Servername is the name of the PreXion server. 1200 refers to the port.

You must use ChartNumber instead of PatNum because the ID used in PreXion is different than the ID used in Open Dental. For each new patient, you will enter them into Open Dental, and then you will again manually enter them into PreXion. PreXion will assign an ID for the new patient, and you must manually enter this ID into the ChartNumber field in the Open Dental Patient Edit window. Once the ChartNumber is entered, the bridge will work for viewing an existing patient's images.
