163 Select device in the device list. You can select "DHCP" or "Static IP".
164
165 * If you select "DHCP", during pass-through, the PC will negotiate with the V-BOX to obtain an available IP address of PC without user intervention.
166 * If "Static IP" is selected, the user needs to fill in the pass-through IP of the PC manually, which will be used for pass-through.

172 **How to choose the pass-through IP of the PC.**
173
174 For PLC and PC LANs using the different network segment.
175
176 * The PLC is directly connected to the V-BOX, and all IPs that are not used by the PLC can be used in the network segment where the PLC is located.
177 * The PLC and V-BOX are connected through a router or switch, and all free IPs not used by the PLC and other devices on the network where the PLC is located can be used in the network segment where the PLC is located.
178
179 For PLC and PC LANs using the same network segment.
180
181 * The PLC is directly connected to the V-BOX and all free IPs not used by the PLC and other devices on the network where the PLC is located can be used within the network segment where the PLC is located.
182 * The PLC and V-BOX are connected through a router or switch, and all free IPs in the network segment where the PLC is located that are not used by the PLC, other devices on the network where the PLC is located, and other devices on the network where the PC is located can be used.
