SYSTem:COMMunicate:LAN:LIPaddress?
Returns the “last valid Auto IP address used” in dot notation (for example:
“169.254.20.11”).
SYSTem:COMMunicate:LAN:MAC?
Returns the 33210A’s Media Access Control (MAC) address. This is an
unchangeable 48-bit address assigned by the manufacturer to each unique
internet device. The MAC address is represented as 12 hexadecimal characters in
the form “XX-XX-XX-XX-XX-XX” (for example, “00-30-D3-00-10-41”).
SYSTem:COMMunicate:LAN:MEDiasense {OFF|0|ON|1}
SYSTem:COMMunicate:LAN:MEDiasense?
Disables or enables the MEDiasense feature. When enabled, this feature detects a
loss of LAN connectivity greater than 20 seconds, and then, on sensing a
reconnection, re-starts the LAN. The factory setting is enabled (ON). The query
returns “0” (OFF) or “1” (ON).
– If you change the MEDiasense setting, you must cycle power on the
instrument to activate the new setting.
– The MEDiasense setting is stored in non-volatile memory, and does not
change when power has been off, or after an instrument reset (*RST).
More About Dot Notation: 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 33210A assumes that all dot-notation addresses are expressed
as decimal byte values 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.
