receive level is above the carrier threshold, the Viper will try to determine if it is receiving
valid data or just noise. If it is receiving noise, the Viper will go ahead and transmit. If it is
receiving valid data, the Viper will wait until the complete packet has been received before
transmitting. The Viper will typically take somewhere between 5 ms to 250 ms to
determine if it is receiving valid data or just noise.
Disabled:
In this mode, the Viper will attempt to receive/decode data when the received
RF level is above the carrier sense threshold. When the Viper has data to transmit it will
immediately transmit the data. The Viper will immediately stop receiving any packets and
will transmit over any other Vipers that are on the air and over any interference that may
be in the area.
This mode should only be used in a polling type environment where the user has strict
control over the traffic that is generated.
IP SERVICES
RIPV2
Enabled, Disabled (default). Router Information Protocol v2 is a dynamic IP routing
protocol based on the distance vector algorithm and is only used in Router Mode. RIPV2
is responsible for passing router information to other routers in the network.
IPSD
Enabled (default), Disabled. I/P Services Delivery allows the generation of locally
provided I/P Services such as online diagnostics, etc.
NAT
Enabled, Disabled (default). Network Address Translation (NAT) is a method by which IP
addresses are mapped from one address space to another. In a Viper, it is normally
used on the WAN side of an IP network to hide local IP addresses from an external IP
network (example: the Internet).
