Netmask
Set to a valid IP Netmask for each individual unit (depends on customer's IP network
topology, default: 255.255.255.0).
DHCP Server
DHCP Server Disabled, Enabled (Default). The Dynamic Host Configuration Protocol provides
a framework for passing configuration information.
E.g.: Assigns IP address to Hosts (i.e. PC/RTU) on a TCP/IP network.
Start Address
Pool of addresses allocated for DHCP purpose. If a unit is configured as a DHCP Server, this
field represents the start IP address pool managed by the DHCP Server. Normally, Viper
automatically calculates the Lease Start Address (equal to Ethernet IP Address plus one).
Number of Leases
Maximum number of DHCP client(s) a unit can serve.
Lease Duration
The period over which the IP Address allocated to a DHCP client is referred to as a "lease".
Lease Duration is the amount entered in minutes. If 0 (zero) is entered, the lease will not
expire.
Gateway
The Gateway text box displays the IP address of the gateway assigned by the DHCP server.
In Router mode, the default (preset) gateway is the IP address of the unit itself. In Bridge
mode, the default (preset) gateway is 0.0.0.0. To override the default setting, enter a valid
IP address in the text field.
MTU
Maximum Transfer Unit - Default = 1500 bytes. The MTU is the maximum number of bytes
the unit will send in a packet. The input range is from 576 to 1500.
MAC Address
The Ethernet MAC address (media access control) is the unique address that a manufacturer
assigns to each networking device. AA:BB:CC:DD:EE:FF The user can not change the
Ethernet MAC address.
1.1.31
RF Interface
IP Address
The RF IP address (default: assigned by factory based on the unit's MAC address) is the RF
IP address that is used when sending data and control packets in a Viper network.
