What do I do when SN0148 cannot be discovered on the network?

Please ensure the searching computer and SN0148 are on the
same IP range, restore the setting to default and use IPInstaller to
enumerate it.

Note:

The IPinstaller may be downloaded from  aten-usa.com  SN0148 page under Resources / Software and Driver

http://www.aten-usa.com/products/KVM/Serial-Console-Server/Serial-Console-Server~SN0148.html#.V0Me2VJOXyM   then select Resources then Software and Driver
