An Firmware upgrade for an B426-M IP Module can be achieved by having the firmware upgrade file and using an laptop to browse into the module over the same IP network it is operating on.
To do so the B426-M module MUST have Firmware upgrade enable turned on (ENABLED) in system programming by the Installer.
The above setting can only be changed by the Installer using AlinkPlus and cannot be changed by an End User or codepad programming
The Module IP Address may also be found by logging into the customers IP router using a laptop and browsing to the connected devices
The device name for the B426-M module would appear as Bxxxxx and you would see the local IP address.
You need this IP address for the next step.
