Where can I find the software to manually configure the Zigbee interface?
The OEM (DTK Electronics) hosts the software tool on their website at www.dtkcn.com. You can click on this link for a direct download. Note that the website does not use https yet, so if the links do not work, you can change the URL to http instead. For information on how to use the tool, please download and read the manual found on the product description page.
