• red background indicates, that the item is monitored for alarm and its average value is in the alarm
range (Settings/Device/Alarm management)
• when the value of RSS, DQ, Ucc, Temp, PWR, VSWR is not known, N/A is displayed. These N/A
values are not displayed in Graphs
• Ucc, Temp, PWR, VSWR are refreshed every 1s. The other values in both, Neighbours and Statistics
tables are refreshed every 20s
• IP addresses:
○
Bridge mode
Due to broadcast pattern of traffic in Radio channel, all frames generated by user application(s)
cumulate in one line in the Neighbour table. When diagnostic or service frames (e.g. Watched
values) are transmitted in the network, they are listed in separate lines, distinguished by IP ad-
dress of their respective Ethernet interfaces.
○ Router mode
MAC addresses of Radio interface are used for link layer communication on Radio channel.
When RipEX knows the IP address corresponding with the MAC address (the IP has been the
destination IP of a packet transferred), IP address is displayed. If the IP address is not known,
the MAC address is displayed.
The first three columns are logged by the receiving RipEX itself.
○
Received headers [Count]
Total number of frame headers received from the respective RipEX.
○ RSS [dBm]
Received Signal Strength.
○ DQ
Data Quality of received frames. The DQ value is about proportional to BER (bit error ratio) and
about independent of the data rate and modulation used. Consequently when data rate is lowered,
the DQ value increases and the other way round. Judging the DQ values requires experience,
rule-of-thumb figures are as followsvalues: DQ below 100 means the link is unusable, aroundt
125 short packets starthould getting through, about 160 and above can be considered “good”
values.
The remaining columns contain values broadcasted by neighbouring units in their Watched values
broadcasting periods(Settings/Device/Neighbours&Statistics).
○
TxLost [%]
The probability of a transmitted frame being lost (100 * Lost frames / All transmitted frames).
This value is broadcasted only when Router mode is used and ACK is On.
○ Ucc [V]
Power voltage measured on power input.
○ Temp [°C]
Temperature inside of the RipEX.
○ PWR [W]
The actual value of Radio output power measured by RipEX itself.
○ VSWR
Voltage Standing Wave Ratio (1.0=best, 1.0–1.8=acceptable, >2.5=indicates a serious problem
in antenna or feeder)
○ Packets [Rx/Tx]
The total number of packets received from / transmitted to ETH, COM1, COM2 interfaces.
Can be used for interface activity diagnostic.
