Introduction
Monitors purchased before May 2020 were fitted with a Wi-Fi/GSM cellular antenna. However, if you need a 4G/LTE connection, you can replace that antenna with a LTE/GPS antenna using an upgrade antenna kit. The replacement antenna forgoes Wi-Fi but adds GPS capability. If required, you can maintain Wi-Fi by adding an internal Wi-Fi antenna to the monitor’s embedded PC.

-
The monitor has a built-in cellular antenna on the outside roof of the enclosure (left side).

-
Disconnect power from the monitor.
-
Open the door and disconnect antenna leads from the embedded PC and modem (if installed).

Disconnect the power and DB9 connectors from the embedded PC. Take note of which port each cable is plugged into as incorrect re-connection could result in sensors appearing offline.

Remove all components from the top left of the monitor - the embedded PC and, in the case of the AQS 1, the gas modules and gas inlet tubing.

-
-
Loosen the antenna retaining nut and remove the old antenna from the top of the monitor.

-
Reinstall the embedded PC and connect power and communications wiring.
-
Connect the antenna wiring to the modem (LTE cable to cellular connection, and GPS to GPS connection on modem, if your modem has GPS capabilities).
-
Connect the internal Wi-Fi antenna to the embedded PC Wi-Fi connection.
-
If you have an AQS 1, reinstall the gas modules and gas inlet tubing.
