On the Apex, there are two BNC connectors. The one which is labeled pH/ORP is modal (meaning selectable); it can be configured for use with a pH probe or with an ORP probe. If you are seeing a pH2 reading, then you need to disable pH 2 and enable ORP.
This video shows how to change the port from ORP to pH2. You need to do the opposite, but this video should get you on the right track.
