The R&S LCX changes the VNC port address accordingly.

Note: The VNC 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 VNC address to the default value, see "Reset-

ting the instrument to the initial factory settings" on page 145.

Assigning the FTP port address manually

Using an FTP application, the remote controller addresses the R&S LCX instrument

with the port address. The R&S LCX has the factory-set address 21, but you can adjust

it manually according to your network environment. It is assumed that you have estab-

lished the connection, see "Establishing the LAN connection" on page 24.

To set the FTP access settings manually:

1. Press the [settings] key at the front panel.

2. In the device settings menu, select "Interfaces" > "Network" > "FTP".

Note: You can modify the settings only when FTP is deactivated.

Initially, the assigned user name is the <instrument name>, e.g., "LCR200".

a) Select "User name".

b) Enter the user name, e.g., MyLCR Meter1. You can specify any sequence with

at least 1 letter and 1 digit.

Confirm with .

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.

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".
