Default = 5000 ms. The time period in milliseconds the Viper will look for a duplicate message being sent, such as control and relay messages. If a duplicate message is detected it will not be forwarded.
Default = 1. This parameter specifies the number of times the MAC layer in the Viper will try to resend a packet if the unit does not receive an acknowledgement reply from the receiving Viper. Acknowledgments must be enabled and can be configured under Setup (Advanced) - IP Optimization.
Default = 128. The RTS threshold parameter specifies how large a packet must be before the unit will use RTS/CTS handshaking in the over-the-air protocol. RTS/CTS handshaking protocol enables the Viper network to avoid collisions in networks with multiple coverage areas. A value of 0 means the Viper will always use over-the-air RTS/CTS handshaking. A value equal to the RF_MTU (over-the-air maximum transmit unit) means the Viper will never use RTS/CTS handshaking. A value of 128 means the Viper will use RTS/CTS for packets larger than 128 bytes.
Default = -110 dBm. This is the threshold the Viper uses to determine whether a received RF signal is a valid message or unwanted noise. If an RF level higher than the Carrier Sense Level Threshold is detected, the Viper will attempt to decode the signal and will not transmit until the RF level drops. Outgoing data will be buffered until the channel is available. The carrier sense may be raised to prevent false carrier sense detection if the network is installed in a noisy environment. In certain situations where the ambient RF noise level is very low, the carrier sense level threshold can be lowered to gain extra receive sensitivity. (The Viper's specified receive sensitivity depends upon the channel bandwidth/speed being used. Refer to the product specification for details.)
Default = Enabled (listen to noise and data). This parameter tells the Viper if it can (or not) transmit data when it is detecting a RF signal (data or noise).
