INK
The LINK command is responsible for configuring radio’s operation
mode. It has six parameters listed below.
LINK [Parameter Name] [Parameters List] [/?]
Parameter
Name
Parameter List
PROT
1 – Simplex “Receiver”
2 – Simplex “Transmitter”
3 – “Repeater”
4 – Secondary “Transceiver” (default)
5 – Primary “Transceiver”
6 – Full duplex
DELAY
0 – No Delay (default)
The delay (1 – 7) is required delivering the data to the destination
receiver. The number of repeaters in the chain defines this value.
MOD
1 – DBPSK
2 – DQPSK (default for AW)
3 – D8PSK
4 – 16QAM
PWRB /
PWRW
(13 – 33) / (20 – 2000) – RF output Power in dBm / mW
CHAN
Selects the frequency channel, CN = (1 – 32). The maximal value
is defined by number of frequencies in the channel list. The CN = 0
is reserved to set the Frequency Automatic scanning mode.
FHOP (1 – 128) – Frequency Hoping Pattern number
SCRAM
0 – No Scrambling (default)
(1 – 255) – Seed for Pseudo-Random Sequence Generator
ENROL
Enrolls the secondary units into the wireless cluster. The enrolled
unit’s 6-digit serial numbers are delimited by commas SN
1
, SN
2
,
SN
3
... SN
31
, SN
32
. The number of units in the cluster does not ex-
ceed 32.
FEC
0 – Disable Forward Error Correction (FEC)
1 – Enable Reed-Solomon encoding
ARQ
0 – Disable ARQ
(1 – 8) – Number of Requests
Note: The frequency defined by CHAN parameter is not valid if
Frequency Hopping mode is selected.
In the Frequency Hoping mode, the Frequency Pattern gen-
erator must generate random numbers smaller than the
number of frequencies listed in the unit’s frequency list.
The ENROL parameter is not valid if the “Receiver” protocol
is selected
