SYSTem:COMMunicate:LAN:IPADdress
Syntax
SYSTem:COMMunicate:LAN:IPADdress "<address>"
SYSTem:COMMunicate:LAN:IPADdress? [{CURRent | STATic}]
Description
This command assigns a static Internet Protocol (IP) address for the instrument. Contact your network
administrator for a valid IP address to use for your instrument.
If you change the IP address, you must send the SYSTem:COMMu-
nicate:LAN:UPDate command to activate the new setting.
Parameters
Name Type Range of Values Default Value
<address> Quoted String Specified in four-byte dot notation
("nnn.nnn.nnn.nnn"),
where "nnn" in each case is a byte value
in the range
0 through 255.
This is a required para-
meter
Remarks
l If DHCP is enabled (see SYSTem:COMMunicate:LAN:DHCP command), the specified static IP address is
not used. However, if the DHCP server fails to assign a valid IP address, the currently configured static
IP address will be used.
l Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value) must be expressed with care,
as most web software on the PC will interpret byte values with leading zeros as octal numbers. For
example, "255.255.020.011" is actually equivalent to decimal "255.255.16.9" not "255.255.20.11"
because ".020" is interpreted as "16" expressed in octal, and ".011" as "9". To avoid confusion, use only
decimal expressions of byte values (0 to 255), with no leading zeros.
For example, the instrument assumes that all dot-notation addresses are expressed as decimal byte val-
ues and strips all leading zeros from these byte values. Thus, attempting to set an IP address of
"255.255.020.011" will become "255.255.20.11" (a purely decimal expression). Be sure to enter the
exact expression, "255.255.20.11", in your PC web software to address the instrument. Do not use
"255.255.020.011" – the PC will interpret this address differently due to the leading zeros.
l If you are planning to use a static IP address on a Corporate LAN, contact your network administrator to
obtain a fixed IP address to be used exclusively for your instrument.
