LAN Connection
Power amplifier is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found at www.lantronix.com .
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. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. There is no default user name or password. It is highly recommended to secure web interface with username and password.
For remote control and monitoring over LAN special software is needed. It is available free of charge; it can be downloaded from the following link: Remote control software version 3.36
NOTE: For the correct functioning of the software, it is necessary to have accessible LAN ports 9999 and 10001
