I've had success with assigning an IP address to the AXC F 2152 without the AXC F XT ETH 1TX, but when I configure it with the extension module it no longer works. I am trying to assign 192.168.10.10 to the extension module and 10.x.x.x. to the TCP/IP port. The status says ok after assigning the properties to the controller, but I can no longer connect to it via either interface. I can get the desired settings to work by setting them using putty, but I don't want to have to train everyone else to do it that way.
