Can't Connect Over LAN

[Error7]

I've had to create a separate LAN from my main network because it is set up to 192.168.0.xxx. This is how I've configured my temporary LAN: I changed the IP address on my laptop to 192.168.1.14 then connected it to a spare router configured to  192.168.1.1. and connected the KC868-A16 to the router. When I run the flash_download_tool from my Windows GUI it results in the error as described previously.

The firmware update is done over USB, you shouldn't need to do anything with a LAN.

Leading to a followup question, are you trying to update it over a LAN?  That would explain the error message you're seeing, the update is done over USB.

Thanks for that information. I'll give that a try and let you know how I get on.
