Rev Version 2.24

Appendix A - FIRMWARE UPGRADE

Determine the firmware version present in the module to be upgraded by viewing the index webpage 

of the module. Firmware versions 1.0.3 and later may be upgraded via the Configuration webpages. This 

upgrade can be executed locally with a PC connected directly to the module, or remotely over a working 

radio link. For remote upgrades, it is advisable to reduce radio traffic over the link from other devices as 

much as possible. If necessary, create a temporary separate radio network to perform the upgrade to 

remote modules.

Web-based Upgrade

Web-based firmware upgrades are available from the System tools page by selecting “Firmware Upgrade.” 

A firmware upgrade is performed by uploading a “patch” file that is specific to the currently installed 

firmware version. If the device firmware version has fallen multiple versions behind the desired version, it 

may be necessary to upload multiple patch files. After the patch files are uploaded, reset the module to 

perform the firmware upgrade. You will receive more detailed instructions if it is necessary to upgrade the 

module firmware.
