The Air Access model AA-LTEA-PW is a multi-function communicator and supervised Air Access interface module. The Air Access system allows you to upload and download lock programming features wirelessly, using the Air Access programming software. The AA-LTEA communicator is one link in the system that facilitates wireless communications between the Air Access software and an individual Networx wireless lock mounted on a protected door. As shown in the following illustration, the Air Access software is accessed through a secure Internet (cloud) connection. The software data is transmitted through a secure cellular connection to an AA-LTEA-Series communicator. The AA-LTEA communicator can be wired directly to a single Air Access Gateway module (e.g. the AAGATEWAYPOE), or if multiple Gateways are needed, the AA-LTEA communicator must be wired directly to a standalone Ethernet switch located within the protected premises. The Ethernet switch can then be wired to up to six (6) Air Access Gateways. Each Gateway is wirelessly connected via a private wireless signal to up to 63 wireless locking devices.
