SYSTem:COMMunicate:LAN:GATeway
Syntax
SYSTem:COMMunicate:LAN:GATeway "<address>"
SYSTem:COMMunicate:LAN:GATeway? [{CURRent | STATic}]
Description
This command assigns a default gateway for the instrument. The specified IP Address sets the default gate-
way which allows the instrument to communicate with systems that are not on the local subnet. Thus,
this is the default gateway where packets are sent which are destined for a device not on the local subnet,
as determined by the Subnet Mask setting. Contact your network administrator to determine if a gateway
is being used and for the correct address.
If you change the default gateway, 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 default gateway is
not used. However, if the DHCP server fails to assign a valid IP address, the currently configured default
gateway 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 a default gateway 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.
