Why would IP address on VLinx box changes to all 255's
Solution:
Why is the IP address changing on its own to all 255's. Unit then becomes unreachable. If you send a blank or empty string or Alpha Characters, to the ip address through the sdk or api, the server will go to all 255’s. Must access the unit through the console port ( except ESP904) to change the IP address back to a valid IP address. ESP904 does not have a switch to select Console Mode. If unit is unreachable, then there is no way to connect to it. It would need to be sent in under RMA. It looks like sending anything but a valid ip address will make the server read all 255’s. FYI, the dll for programming WILL allow non ip addresses to be programmed and the resulting failure mode is all 255’s in the ip address and gateway.
