LAN Configuration
LAN Configuration
Configures instrument for remote operation via the local area network (LAN).
Dot Notation Details
Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value from 0 to 255) must be expressed with care,
as most PC web software interprets byte values with leading zeros as octal (base 8) numbers. For example,
"192.168.020.011" is actually equivalent to decimal "192.168.16.9" because ".020" is interpreted as "16" expressed
in octal, and ".011" as "9". To avoid confusion, use only decimal values from 0 to 255, with no leading zeros.
SYSTem:COMMunicate:LAN:CONTrol?
Reads the initial Control connection port number for Sockets communications. This connection is used to send and
receive commands and queries.
Parameter
(none)
Return the Control connection port number:
SYST:COMM:LAN:CONT?
Use the Control socket connection to send a Device Clear to the instrument or to detect pending Service Request
l
(SRQ) events. The Device Clear command is "DCL".
SYSTem:COMMunicate:LAN:DHCP {ON|1|OFF|0}
SYSTem:COMMunicate:LAN:DHCP?
Disables or enables instrument's use of DHCP. The acronym DHCP stands for Dynamic Host Configuration Protocol, a
protocol for assigning dynamic IP addresses to networked devices. With dynamic addressing, a device can have a dif-
ferent IP address every time it connects to the network.
ON: instrument tries to obtain an IP address from a DHCP server. If a DHCP server is found, it assigns a dynamic IP
address, Subnet Mask, and Default Gateway to the instrument.
OFF or DHCP unavailable: instrument uses the static IP address, Subnet Mask, and Default Gateway during power-
on.
If you change this setting, you must send
setting.
Parameter
{ON|1|OFF|0}, default ON
Disable DHCP:

The instrument uses LAN port 5024 for SCPI Telnet sessions, and port 5025 for SCPI
Socket sessions.
Typical Return
5000 (0 if the interface does not support sockets)
Typical Return
0 (OFF) or 1 (ON)
