Compatible adapters for Watchport D sensor

Hi guys,
I have recently started playing digi products. I bought a couple Watchport/D sensors on the Digi website. They have an RJ-45 interface.
I am looking for compatible adapters for them. I searched online and I found an adapter called XA-B14-CS1R but unfortunately that adapter is now obsolete. Can anyone help me with information on an equivalent adapter for Watchport/D sensor with RJ-45 connector ?

Thanks.

Another piece for information for my question: XA-B14-CS1R is (XBee Sensor Adapter ZNet 2.5) and I am looking for an equivalent of this adapter.

Thanks.
