Setting up DVPEN01-SL Network
1. IP configuration:
There are two types of IP, static IP and DHCP.
Static IP: Preset or manually modified by the user.
DHCP: Automatically updated by the server. There has to be a server in the LAN.
IP Explanation
Static The user enters the IP address, subnet mask and gateway.
DHCP DHCP server offers the IP address, subnet mask and gateway.
2. IP address:
IP address is the location of the equipment in the network. Every equipment connected to the
network has to have an IP address. Incorrect IP address will result in connection failure on the
equipment or even other equipment. Ask your ISP for questions about IP address setup. The default
IP for DVPEN01-SL is 192.168.1.5.
3. Subnet mask:
Subnet mask is an important parameter for setting up the subnet, used for seeing if the destination
IP and the local equipment are in the same subnet. If not, the equipment will send the packet to the
gateway, and the gateway will send the packet to another subnet. Incorrect setting may cause the
destination equipment unable to communicate with DVPEN01-SL. To see if your setting is correct,
conduct bitwise AND operations between your IP and subnet mask and destination IP and subnet
mask. If the two values obtained are the same, the two IPs are in the same subnet. The default
subnet mask of DVPEN01-SL is 255.255.255.0.
4. Gateway:
Gateway is the gate for two different subnets, allowing the two ends in different subnets to
communicate. For example, if the LAN has to be connected to WAN, it will need a gateway to bridge
the communication. The IP of the gateway has to be in the same subnet as DVPEN01-SL. The
default gateway IP address of DVPEN01-SL is 192.168.1.1.
