Manoj,
I got it working. I had to enable external API in the web switch browser to get it going. Tiddler works great. Dan is still having problems. I would go to the external API and enable all of them to see if it starts working then disable them one by one to see if it stops working (wait a few seconds for the tiddler to update). It seems like the firmware version has an impact on how the switch communicates(I'm leery of updating firmware after ruining DVD burners after an upgrade). I'm glad you came up with a solution because Digital Loggers are unfamiliar with customer service and never respond to help requests.
