LAN connection
The power amplifier is interfaced to the LAN via XPORT produced by Lantronix (type XP1001000-05R). More information can be found at www.lantronix.com.
The default factory settings of XPORT are:
IP Address: 192.168.1.222
Mask: 255.255.255.0
Gateway: 192.168.1.1
These are strictly default settings. Any of these can be changed by accessing the XPORT Web GUI via your Web browser. It is not recommended to change other parameters of the XPORT interface as loss of communication can be caused by this. There is no default username or password. It is strongly recommended to secure the web interface with a username and password.
Special software is required for remote control and monitoring over LAN. It is available for free, it can be downloaded from the following address:
