How to Upgrade
The following methods are available for upgrading units in the field.

2: Upgrade using E100 Web Interface – This method can be used to upgrade the E100/E100-S, E200, and the LON-board. See below for more details.
LON-board Firmware
The LON app can be upgraded using one of the following methods.
1. Upgrade using USB LON-Module – This method can be used to upgrade the LON-board with an additional piece of 3rd party hardware (not sold by acre Security): U10 USB Network Interface – TP/FT-10 Channel.
2. LON-Board swap between E200 and E100 – This method can be used to upgrade the E100/E100-S’s LON-board without the use of a LON-module. For instructions, please see manual: A-100435-10_Omnis_Discovery_and_Web_Tool-EN-SV.
