2.2.2 ROUTER MODE

Router mode allows greater network configuration flexibility, allows the use of a variety of protocols, and also adds RF
diagnostics capability to Viper networks. Diagnostics can be retrieved through the Ethernet port of the Viper. For more
information on Viper RF Diagnostics, refer to Section 4.1.2
Router mode requires the setup of Ethernet IP and Serial IP addresses and is recommended only for users who have
IT/Network support readily available to them and/or the authorization required to make changes in to the network.
In Router mode, each Viper uses two IP addresses:
The Ethernet IP Address
The RF IP Address
Every Viper is factory configured with a default Ethernet IP Address 192.168.205.1 and a unique RF IP address. This RF IP
address will have the form 10.x.y.z where x, y, and z is based on the last 6 digits of the unit's Ethernet MAC address. The
default network is 10.0.0.0/8.
In Router mode, each Viper must have its Ethernet IP Address on a unique network and all Vipers must have their RF IP
addresses on the same network. For consistent and reliable communication, the RF network addresses should not overlap
or contain any of the IP Addresses in the Ethernet network.
Router Mode Example 1
In this example, each Viper has an Ethernet IP address on a unique network. For Vipers #1, #2, and #3, each network
connected to their local Ethernet ports has 254 valid IP addresses that may be assigned to other hosts. The network
connected to Viper #4's local Ethernet port has 65534 valid IP addresses.
Note 1: All Vipers' RF IP addresses are on the same network. Because they are using the 10.0.0.0/8 network, all Vipers may
use the default RF IP address programmed by the factory.
