― Start Address . Represents the 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. Represents the 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 . Displays the IP address of the gateway assigned by the DHCP server. In Bridge mode, the default gateway is
0.0.0.0. In Router mode, the default gateway is the IP address of the unit itself. To override the default setting, enter a
valid IP address in the text field.
― MTU (Maximum Transfer Unit). Enter a value from 576-1500. Default = 1500. The MTU is the maximum number (in
bytes) the unit will send in a packet.
― MAC (Media Access Control) Address. This is the unique address that a manufacturer assigns to each networking
device. Users can not change the MAC address.
4.3.2.2 RF INTERFACE
― IP Address. Default = 10.128.13.68. The RF IP address is the address that is used when sending data and control packets
in a Viper network. The Netmask (Default = 255.0.0.0.) must be the same for all Viper in the network.
― MTU (Maximum Transfer Unit). Enter a value from 576-1500 . Default = 1500. This value represents the maximum
number of bytes Viper will send in a packet.
― MAC Address. Default = 00:0E:81. The RF MAC Address is a shortened version of the Ethernet MAC address which is
used to identify the radio to other Viper SCs on the network. The default RF MAC address is assigned by the factory and
is equal to the last six digits of the Ethernet MAC address (DD:EE:FF). While users cannot change the Ethernet MAC
address, they may enter a new RF MAC address for the device. The RF MAC address must be unique for each Viper in
the network. When the network is configured for router mode, this feature is useful when replacing a Viper in the field
with a new one. The new Viper can be programmed to have the same RF MAC, Ethernet IP Address, and RF IP Address
as the Viper that is being replaced. When the new Viper is installed, neighboring Vipers in the network will not know
the original Viper was replaced. Neighboring Vipers will not need to have their neighbor tables updated.
― Default Gateway. Default = 0.0.0. Allows the user to enter the IP address of the access point to be used as the gateway
to the management network. If there is one Viper SC configured as an Access Point in the network, all the other Viper
will set their Default Gateway equal to the RF IP address of the Access Point.
4.3.3 CHANNEL TABLE
The Channel Table will display the Transmit Frequency, Receive Frequency, Transmit Power, Bandwidth, and Data Rate for
each channel in the unit.
