    3-2. PC Network Settings To control the IVS-200 over a LAN interface, the PC network settings need to match those of the IVS-200. The procedure for setting network settings on the PC vary depending on the OS, so refer to the OS manual for details. This section describes an example set of settings for connection to an IVS-200 with its default settings.
