Setting the subnet mask
You can set the subnet mask for your LAN connection. This menu option assigns a 
Subnet Mask for the instrument. The instrument uses the Subnet Mask to 
determine whether a client IP address is on the same local subnet. You must 
disable DHCP in order to set this on the front panel.
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 whether 
subnetting is being used and for the correct Subnet Mask.

this menu option. You must disable DHCP in order to set this on the front panel.

address assigned with this menu option. You must disable DHCP in order to set 
this on the front panel.
