Ethernet Connectivity

To connect the Pax A800 via ethernet you'll need to have an additional Pax communication hub. Please reach out to support about acquiring additional hubs.

Each Pax communication hub will have it's own unique MAC address that will be associated with the connected A800 device.

If the above options do not solve the problem, contact the Finix Support Team.
