To connect the R&S LCX to the controller PC:
1. Connect the IEC 625/IEEE 488 connector of the R&S LCX to the controller PC with
a double-shielded GPIB bus interface cable.
2. Configure the settings for remote control as described in "Assigning the GPIB
address manually" on page 173.
The controller must address the instrument with the GPIB bus address, see Sec-
tion 10.2.3, "GPIB interface (IEC/IEEE bus interface)", on page 155.
10.5 Adjusting interface addresses
Depending on the network capabilities, the TCP/IP address information for the instru-
ment can be obtained in different ways.
●
If the network supports DHCP (dynamic host configuration protocol), the address
information is assigned automatically. This mode enables you to establish a physi-
cal connection to the LAN without any additional instrument configuration.
●
If the network does not support DHCP, or if the instrument is set to use an alternate
TCP/IP configuration, you must set the addresses manually, see "Assigning the
LAN interface addresses manually" on page 169.
●
SCPI Raw Port
As an alternative, you can establish a raw TCP/IP connection using sockets for
sending raw SCPI commands to the instrument. To configure the connection,
assign the port, and, if necessary, the host name of the instrument, see "Assigning
the SCPI raw port and hostname manually" on page 172.
Assigning the LAN interface addresses manually
If the network provides DHCP, this protocol assigns the IP address automatically
(default setting). But you can also assign the address manually, if necessary. It is
assumed that you have connected controller PC and the instrument, see "Establishing
the LAN connection" on page 24.
To assign the IP addresses for the LAN interface manually:
1.
NOTICE! Risk of network failure. Connecting to the network can cause network
failure. Errors can affect the entire network.
Consult your network administrator before performing the following tasks:
● Connecting the instrument to the network
● Configuring the network
● Changing IP addresses
2. Access: see 159
3.
Turn "DHCP & Auto-IP'".

The R&S LCX enables edit mode.
4. Select the "IP Address".
The IP address consists of four blocks separated by dots. Every block contains 3
numbers at a maximum.
5. Enter the address, e.g. 123.123.1.123.
6.
Confirm with .
7. Set the "Subnet Mask" and "Gateway" in the same way.
8. Select "Apply Configuration".
The R&S LCX applies the modified settings.
9. To undo the changes, select "Reset LAN Connection".
Note: The MAC address is assigned statically and cannot be modified.
10.
Return with
.
When the connection is established successfully, the R&S LCX displays the white
network icon in the instrument status bar.
Assigning the VNC port manually
Using a VNC client, you can access the R&S LCX remotely over the VNC interface.
The controller addresses the instrument with the port address. The R&S LCX has the
factory-set address 5900, but you can adjust it manually according to your network
environment. It is assumed that you have established the connection, see "Establishing
the LAN connection" on page 24.
To set the VNC port manually:
1. To access the setting, press the [settings] key at the front panel.
2. In the device settings menu, select "Interfaces" > "Network" > "VNC".
Note: You can modify the settings only when VNC state is deactivated.

3.
Turn VNC.
4. Select "VNC Port".
An on-screen keypad opens.
5. Enter the port number.
6.
Confirm with
.
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.
3.
Turn
"FTP".
4. Select "Port".
An on-screen keypad opens.
5. Enter the port number.
6. If necessary, assign an individual user name:
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.
c)
Confirm with .
7.
NOTICE! The password is required when you use the FTP function the first time,
and after changing the port and user name.
To change or confirm the password:
Initially, the assigned password is the <serial number> of the instrument, see the
label at the rear panel.
a) Select "Password".
b) Enter the password.
You can specify any sequence with at least one letter and one digit.
