avg / dev / min / max – average / standard deviation / minimum / maximum
Phy header MSE [dB] – modulation Mean Squared Error - measured within the header reception
Freq offset [Hz] – Averaged frequency offset between the transmitter and the receiver station, measured
by the receiver station.
Att1 [%] - First internal attenuator (15 dB) activated. Shown in percents of affected frames.
Att2 [dB] – Value of the 2nd internal attenuation applied.
Data count – Received complete frames (including data part) count. Frames with valid header CRC,
but wrong data CRC are not counted
Data MSE [dB] - modulation Mean Squared Error - measured within the frame data part reception
8.4.6. Radio signal non-addressable statistics
Radio signal statistics provides set of data monitoring the radio interface quantities and events. This
table contains measurements handled before the frame reception and measurements which cannot
be linked with any address (e.g. broadcasts). It corresponds to monitoring Radio - Interface.
Pre-frame – Values based on measurements handled before the frame reception
RSS [dBm] – Radio Signal Strength - measured short time just before the frame reception
Others – Values for frames which cannot be linked with any address
8.4.7. Serial protocol statistics
Serial protocols statistics provides set of data monitoring the COM port(s) and Terminal server (s). Only
enabled interfaces are displayed. The statistics counters are based on packets entering or leaving the
COM port or Terminal server module. As a result of this the 'count' values correspond to the Protocol
messages (the "Protocol" selected on the specific COM port or Terminal server). If the packet is 'glued'
from the several frames, it is evaluated as a single packet. In case of COM port statistic, the summary
of 'Correct' and 'Drop' Bytes provides the total amount of Bytes on the physical interface.
Rx direction: from the connected (at the COM or ETH port) external device to the RipEX2 unit (i.e. from
the COM port module or Terminal server module to the Router module). Tx direction: from the RipEX2
unit to the external device.
