2.8 Basic Configuration of the Radio
The radio can be controlled and monitored via local area network (LAN) with one or more 
external control units also connected to the LAN (see sect. 1.9 Radio Control). To guarantee 
proper operation in this case it is required to change the default Internet protocol (IP) settings 
of the radio (for default IP settings of the radio see Table 2.1) as well as the default IP settings 
of the control unit (for default IP settings of the control unit see sect. 2.9 Basic Configuration 
of the Control Unit) before connecting the radio(s) and control unit(s) to the LAN.
If your radio is controlled via built-in control unit and you do not want to connect your 
radio to a LAN, you may skip the following sections and continue with section 3.
There are two possibilities to change the radio IP settings:
• Using a built-in control unit (if available)
• Using the upd32.exe tool provided by Rohde & Schwarz.
Both are explained in this documentation.
Table 2.1 Default IP Settings of a Radio
Be careful if you change the IP settings. For the configuration of a greater network, 
detailed knowledge concerning IP networks is required. Such knowledge is not im-
parted by this documentation. Please ask your network administrator or refer to ap-
propriate technical literature, if necessary.
