HOWTO: Load new communications parameters into a device (KB1001)

You can load new communications parameters into a device by loading the NDL file with the NodeLoad application using the -X and -! options.


The communication parameters only need to be loaded the first time the application is loaded, or when the parameters are changed (change of system clock for example).


Please note the -! option bypasses the transceiver-compatibility check of the image to be downloaded. You should only proceed if you are sure the image contains the correct parameters, or you might lose communication with the device.


An example command line would be:

nodeload -DLON1 -W30 -! –Xtest.ndl


This example command opens LON1, waits 30 seconds for a service pin, and sets the transceiver parameters from the test.NDL file. Note that this command does not load the application. To load the application, you can use:

 nodeload -DLON1 -W30 –Ltest.ndl


NodeLoad can be downloaded from our Downloads page at NodeUtil and NodeLoad - LON Portal - Confluence (atlassian.net)
