The R&S LCX changes the FTP port address accordingly.
Note: The FTP address settings are retained by an instrument preset, and also
when you recall previously saved instrument settings, see Section 9.12, "Save/
recall", on page 142.
However, a factory reset presets the FTP address to the default value, see "Reset-
ting the instrument to the initial factory settings" on page 145.
Assigning the SCPI raw port and hostname manually
To assign the socket port and the instrument name manually:
1. Access: see 159
2. Select "SCPI Raw Port".
The R&S LCX opens an on-screen keypad to enter the port number.
3. Enter the port number, e.g., 5025.
4.
Confirm with .
5. Proceed the same way to enter the hostname, e.g. LCX200-01.
Assigning the IP address manually on the controller PC
► Obtain the necessary information from your network administrator. If you use more
than one LAN connector, you need separate address information for each connec-
tor.
For information on how to configure the LAN settings, refer to the documentation of
the operating system the PC uses.
Selecting the USB communication class protocol
A USB connection requires the VISA library to be installed. VISA detects and config-
ures the R&S instrument automatically when the USB connection is established. You
do not have to enter an address string or install a separate driver. It is assumed that
you have connected controller PC and the instrument, see "Establishing a USB remote
control connection" on page 168.
To install the driver and select the USB class:
1. Press the [settings] key at the front panel.
2. In the device settings menu, select "Interfaces" > "USB Class".
A selection dialog opens.
3. Select the communication protocol for the USB interface, e.g. "CDC".
4. Confirm your selection.
If you have changed the USB class, the R&S LCX displays a message that
prompts you to reboot.

The instrument must reboot to load the corresponding protocol driver.
5. To proceed, you have the following options:
a) Confirm with "OK".
The R&S LCX reboots and activates the connection. It indicates the selected
USB interface port in the device status bar on top of the screen.
b) If you want to undo your selection, tap any point of the screen outside the mes-
sage.
The message disappears and you can correct your selection.
Assigning the GPIB address manually
Option: R&S NG-B105 GPIB (IEC 625/IEE 488) bus interface
The controller addresses the instrument within the GPIB bus channel, providing
addresses from 0 to 30. The R&S LCX has the factory-set address 20, but you can
adjust it manually according to your network environment. It is assumed that you have
established the connection, see "Establishing the GPIB remote control connection"
on page 168.
To select and enter the GPIB manually:
1. To access the setting, the [settings] key at the front panel.
2. In the device settings menu, select "Interfaces" > "GPIB Address".
An on-screen keypad opens.
3. Enter the channel number.
4.
Confirm with .
The R&S LCX changes the GPIB address accordingly.
Note: The address is maintained after a reset of the instrument settings.
10.6 Operating the R&S LCX remotely
When you switch on the instrument, it is always in manual operation state (local state).
You can operate it using the controls on the front panel. To operate the instrument from
a remote location, see the following possibilities, how to set up remote control connec-
tions over the available interfaces.
Prerequisites to proceed with the following instructions are:
●
You have set up the connection between the R&S LCX and the controller, see Sec-
tion 10.4, "Connecting the R&S LCX for remote access", on page 167.
●
The instrument and the controller are turned on and ready for operation.

10.6.1 Controlling the R&S LCX over LAN
10.6.1.1 Using SCPI commands
Activating the LAN interface
The LAN interface is enabled automatically, when the connection is established and
the IP addresses are valid. To check the settings:
1. Press the [settings] key at the front panel.
2. In the device settings menu, select "Interfaces".
3. Select "Network".
4. Select "LAN".
5.
If turned off, enable "DHCP & Auto IP" .
The "LAN settings" dialog shows the current address configuration of the interface.
Starting a remote control session
To start remote control:
1. Send a command from the controller.
2. VXI-11 protocol (LAN or USB interface): Use &GTR interface message.
The instrument switches to remote control and executes the command.
On the screen, a status symbol indicates that remote control is active. The display
remains on and you can still operate it manually using the front panel controls.
Returning to manual operation
The instrument switches back to manual operation once you close the remote connec-
tion. You can also return to manual operation manually or with a remote command:
To return to manual control:
► VXI-11 protocol (LAN or USB interface): Use &GTL interface message.
The instrument switches to manual control.
