R&S SFD
Networks that assign fixed (Static) IP
In networks that assign static IP addresses, the network administrator usually handles
this process. The fixed IP address must be entered into the unit using an IP connection
and a web browser, see point to point connection below or using a zero-conf address.
See below.
Zero Conf
Many devices support a method of self configuration, it is often called Zero Conf,
Bonjour or mDNS. This is process is specified in RFC 3927. The unit finds a unique
address in the block 169.254.0.0 netmask 255.255.0.0. The device can be found by
browsing the network. The device can be found by looking for a name of the form
"RSSFD-*.local" where the * is replaced by the unit serial number. Open a cmd prompt
(DOS prompt) and ping the unit with the command ping RSSFD-XXXXXX.local. The
ping command will return an IP address. The computer's network configuration may
need to be modified to communicate with the unit. Once the computer's network
configuration is properly set, enter the IP address in a web browser.
Point-to-point connections
To set up a single network (a LAN connection between an instrument and a single
computer without integration into a larger network), an IP address needs to be
assigned to the instrument and the computer. The IP addresses 192.168.10.xxx are
available for use here, where xxx can assume values of 2 to 254, and the value for the
subnet mask is 255.255.255.0. Either a straight or crossover cable can be used as the
instrument automatically detects the configuration of the connected equipment and
reconfigures itself to initiate communication.
Network Configuration Reset
In the event the network is misconfigured or the network configuration is lost, the
network configuration can be reset to the factory default. To reset the network
configuration:
1. Press the "reset" button located at the rear of the R&S SFD unit
2. Hold the button for 3 seconds, then release
The unit will now use the factory default network configuration.
