Note that you've posted in the forum for the 2330L and you say you have a 2230L.
Anyway, this camera has a web interface and you can configure it that way without using a separate software program. Since you say you can see that the camera has an IP address, just enter the IP address into your browser: http://w.x.y.z . You should be greeted with the camera's authentication prompt. Per the user manual, the default ID as "admin" with a blank password. As you've purchased a refurb'ed camera (who refurb'ed it?), there's no knowing whether the default settings including that ID and blank password were applied, but hopefully so. Once you've logged into the web interface, you should be able to configure the camera.
