― RX Ctrl Pkts. The total number of control packets received over-the-air. These packets may be RTS/CTS messages or RF
Acknowledgements.
― RX Data Pkts. The total number of input data packets received over-the-air.
― TX Ctrl Pkts. The total number of output control packets transmitted over-the-air. These packets may be RTS/CTS
messages or RF Acknowledgements.

4.6.3.2.1 AIRLINK ERROR DETECTION
Airlink parameters provide the user with RF link quality information.
― Reliable Service Msg Success Count. The number of service messages that succeeded. RF Acknowledgements must be
enabled in order to generate a Reliable Service Message. RF Acknowledgements can be configured under Setup
― Reliable Service Msg Failure Count. The number of service messages that failed.
― Total Retry Count. The total number of retries for service messages.
― Noise Detected Count. The number of noise (non Viper SC carrier) detected instances above the carrier sense level. If
the Noise detected count is high, it may be an indication the Carrier Sense Threshold should be raised.

Cycling power to the device or pressing the Clear (Zero) Interface Stats button will reset all statistics to zero.
4.6.3.3 STATISTICS/REMOTES
Figure 58 – Statistics/Remotes
Remote Units. The RF MAC address of a neighboring remote unit. This table is updated every time the Viper sends (or
receives) data to (or from) that unit. When the RF MAC address is prefixed by an asterisk ('*'), the Viper learned about this
unit through a Relay Point (RP) (e.g., this unit is more than 1 RF hop away).
Received Packets. The number of IP packets sent by the remote unit to this unit. A packet is bad (failed) if at least one of
the following is incorrect: the CRC, the length, the system identifier or it was simply not received at all by this unit (as
evidenced by a gap in the packet stream sequence numbers). The receive Packet Error Rate (PER) is calculated with this
formula: per = (bad/(bad+good))*100
