Appendix A
Determine which firmware version is present in the module to be upgraded by viewing the index
webpage of the module.
Firmware versions v1.21 and later may be upgraded via the configuration web pages. This upgrade
can be done locally with a PC connected directly to the module, or remotely over a working radio
link. For remote upgrade, 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. Please refer to the "Web based Upgrade" section for the upgrade procedure.
Firmware versions prior to v1.21 require must be upgraded using the FlashUpdate utility, and can
only be performed local to the module. The FlashUpdate utility should also be used if firmware
versions of modules to be upgraded are unknown. The section "Manual Upgrade using Flash Update"
outlines the upgrade procedure.
