IPADDR [n1 n2 n3 n4]  Ethernet IP Address  
When this command is sent without parameters, the instrument responds with the 
current IP address e.g. 169.254.0.10 
When sent with the four parameters, the command sets the IP address that will be 
used when the model 7230 is set to static IP address mode (via the rear panel Config 
Switch 2, see section 4.2.07) 
The parameters are separated by a space character and not by a dot, e.g. 
IPADDR 169  254  0  10 
sets the IP address to 169.254.0.10  Based on the IP address, this command will also 
generate a default subnet mask and gateway address so if values other than the 
defaults are required set the IP address before setting the subnet mask and gateway 
address otherwise they will be overwritten. 
SNMASK [n1 n2 n3 n4]  Ethernet Subnet Mask 
When this command is sent without parameters, the instrument responds with the 
current subnet mask e.g. 255.255.0.0  
When sent with the four parameters, the command sets the subnet mask that will be 
used when the model 7230 is set to static IP address mode (via the rear panel Config 
Switch 2, see section 4.2.07) 
The parameters are separated by a space character and not by a dot, e.g. 
SNMASK 255  255  0  0 
sets the subnet mask to 255.255.0.0 
Note that the setting can be overridden if the IP address is set using the IPADDR 
command. 
GWADDR [n1 n2 n3 n4]  Ethernet Gateway Address 
When this command is sent without parameters, the instrument responds with the 
current gateway address e.g. 169.254.0.1 
When sent with the four parameters, the command sets the gateway address that will 
be used when the model 7230 is set to static IP address mode (via the rear panel 
Config Switch 2, see section 4.2.07) 
The parameters are separated by a space character and not by a dot, e.g. 
GWADDR 169  254  0  1 
sets the gateway address 169.254.0.1 
Note that the setting can be overridden if the IP address is set using the IPADDR 
command. 
IPLOCK  Restrict Ethernet Access 
When this command is sent via the Ethernet interface, subsequent connection 
requests and hence commands will only be accepted if sent from the same IP address, 
preventing unauthorized access to the instrument. 
IPUNLOCK  Remove Ethernet Access Restrictions 
When this command is sent via the Ethernet interface, subsequent connection
