What to do if GridConnect NET232 Adapter shows 'No response from device!' message?
If you receive a 'No response from device!' message when assigning an IP address with Device Installer for your GridConnect Adapter, double-check the IP address, Hardware address, and Network Class parameters that you have entered. It is important to note that you cannot assign an IP address to a server through a router.
Why can I ping GridConnect NET232 but not Telnet to it?
If you can ping your GridConnect Adapter but cannot Telnet to it on port 9999, there might be an IP address conflict on your network, or you may not be Telneting to port 9999. Alternatively, the Telnet configuration port (9999) could be disabled in the server security settings. To resolve this, turn off the server and use the DOS prompt to issue the following commands: 'ARP -D X.X.X.X' (where X.X.X.X is the server's IP address), followed by 'PING X.X.X.X'. If you get a response to the ping, there is a duplicate IP address on the network. If there is no response, use the serial port to verify that Telnet is not disabled.
