Firmware Upgrade Guide

Upgrading the Firmware

How you do firmware upgrades will differ between devices. See the sections below to find the instructions for your device.

1.0 Gateways

This includes the following devices DLOS8N, LG308N, LPS8N, LPS8V2 & LG01V2. This will also be correct for the cellular versions of these devices.

1.1 Access & Configure Web UI

Open a browser on your PC and type the gateway IP address (this will differ depending on your connection method):

http://10.130.1.1/  (If accessing the device via Wi-Fi AP network)

or

http://IP_ADDRESS or http:// IP_ADDRESS:8000 

You will see the login interface of the gateway as shown below.

The account details for the Web Login are:
