34410A/11A User’s Guide 91
Remote Interface Configuration 3
Setting the LAN Subnet Mask
The multimeter uses the Subnet Mask to determine if a client IP address 
is on the same local subnet. When a client IP address is on a different 
subnet, all packets must be sent to the Default Gateway. Contact your 
network administrator to determine if subnetting is being used and for the 
correct Subnet Mask.
• Changing the Subnet Mask setting will cause an automatic LAN reset.
• The default Subnet Mask for the 34410A multimeter is “255.255.0.0”.
• A value of “0.0.0.0” or “255.255.255.255” indicates that subnetting is not 
being used.
• The Subnet Mask is stored in non–volatile memory, and does not 
change when power has been off, after a Factory Reset (*RST) 
command, or after an Instrument Preset (SYSTem:PRESet) command.
Setting the LAN Default Gateway
A Default Gateway address allows the multimeter 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.
• Changing the Default Gateway setting will cause an automatic LAN 
reset.
• The default for the multimeter is “0.0.0.0” (no gateway, and subnetting 
is not being used).
• The Default Gateway is stored in non–volatile memory, and does not 
change when power has been off, after a Factory Reset (*RST) 
command, or after an Instrument Preset (SYSTem:PRESet) command.
