“Power-on Load” (Utility  System  Power On) is set to “Last” and 
“DHCP” and “Auto IP” are “Off” at the next power-on, the oscilloscope will load 
the preset IP address automatically. 
 
5.  Set the subnet mask (when Static IP configuration type is used) 
The format of the subnet mask is nnn.nnn.nnn.nnn; wherein, the ranges of the 
nnn are all from 0 to 255. You are recommended to ask your network 
administrator for a subnet mask available. 
 
Press Mask and turn the multi-function knob   to input the desired subnet 
mask (for the setting method refer to “Network Parameter Setting 
Method
”). This setting will be saved in the non-volatile memory and if 
“Power-on Load” (Utility  System  Power On) is set to “Last” and 
“DHCP” and “Auto IP” are “Off” at the next power-on, the oscilloscope will load 
the preset subnet mask automatically. 
 
6.  Apply the network parameter configuration 
After configuring the network parameters, press Apply to validate the current 
network parameter settings.  
 
Note: The network parameters newly configured will only take into effect when 
Apply is pressed. At this point, the current network setting information in the 
network connection setting interface will be updated according to the current 
network parameter configuration.  
 
7.  Initialize the network parameters  
Press Initialize to restore the network parameters to the default state. 
 
Note: You can only initialize the network parameters when the oscilloscope is 
correctly connected to the network.  
 
8.  mDNS
