7.1.2.7.1. Radio parameters - advanced
There is only one advanced radio parameter
Maximal distance
Number {0 to 200}, default = 100
This parameter allows to set a maximal distance of a radio hop (in km). The same number shall be
used for the whole network. We recommend to change the value only in case that the network uses
radio hops longer than 100 km.
Resilience
List box {High sensitivity; Auto; High resilience}, default = "Auto"
RipEX2 is equipped with cognitive function of receiving mode selection. When exposed in a radio
environment where strong interfering signals (stronger than -45 dBm) are present, RipEX2 senses
them and adaptively increases its resistance to interference (by lowering its sensitivity by up to 2-
3 dB).
Resilience parameter controls this functionality. By default the
Auto
is set - when intereference
holds, RipEX2 stays in High resilience mode of receiver operation and signals this state by turning
the yellow RX LED on. Once the interfering signals fade away, RipEX2 automatically returns to its
High sensitivity mode of receiver operation. It is possible to switch this functionality permanently
off (
High sensitivity
) or permanently on (
High resilience
).
High resilience LED indication
List box {On; Off}, default = "Off"
Enables indication of High resilience mode by yellow RX status LED.
7.1.2.7.2. Queues
TX Buffers
The Radio protocol transmission buffer handles data waiting to be transmitted. Its size is defined
by both the number of records (Queue length) and total storage space (Queue size) requirement.
Records are held in a queue which is considered full, if either the Queue length or Queue size is
reached. New incoming frames are not accepted when the queue is full.
The TX buffer is active for all radio protocols.
This functionality is available in ADVANCED/Interfaces/Radio/Queues menu
Queue length [packets]
Number {1 – 31}, default = 5
Queue length dictates the maximum number of records held in the queue.
Queue size [kB]
Number {1 – 48}, default = 5
Queue size dictates the total size of all records that can be held in the queue.
TX Buffer timeout enabled
List box {Off; On}, default = "Off "
The frames waiting for transmission in the Radio protocol output frame queue will be discarded
after the TX Buffer timeout expires. This parameter should be enabled for types of applications
where sending old frames brings no benefit.
When the frame is discarded the event is recorded, both in the statistics (as “Rejected”) and in the
monitoring (the respective frame is displayed with the “Tx buffer timeout” tag).
TX Buffer store timeout [s]
Number {0.01 – 150}, granularity 0.01, default = 5
