Netmask
The Netmask (default: 255.0.0.0) is set to a valid common RF IP Netmask for all units in a
Viper network.
MTU
Maximum Transfer Unit - Default = 1500 bytes. The Maximum transfer unit is the
maximum number of bytes the unit will send in a packet. The input range is from 576 to
1500.
MAC
The RF MAC is a shortened version of the Ethernet MAC address which is used to identify
the radio to other Vipers 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). The user
can override the default RF MAC address by entering the new RF MAC address in the MAC
address field under the RF Interface section.
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.
The RF MAC address must be unique for each Viper in the network. This applies to both
Bridge and Router mode configurations.

Default Gateway
The Default Gateway (default: 0.0.0.0) allows the user to enter in the IP address of the
access point to be used as the gateway to the management network. If there is one Viper
configured as an Access Point in the network, all the other Vipers will set their Default
Gateway equal to the RF IP address of the Access Point.
CHANNEL TABLE
The Channel Table will display the Transmit Frequency, Receive Frequency, Transmit Power,
and Channel Type for each channel in the unit.
