To connect to the Base unit, through the remote unit, the parameter (Unit_Numb) must be equal to
0. To connect the local unit (Base or Remote), the parameter (Unit_Numb) must be equal to 0xFF.
3.2.2. LINK
The LINK command is responsible for configuring radio’s operation mode. It has six parameters
listed below.

Parameter Name Parameter List
PROT 1 – “Simplex Receiver”, a default setting for Remote units
2 – “Simplex Transmitter”
3 – “Half Duplex” specific for remote units (Reserved for future use)
4 – “Half Duplex” specific for base unit (Reserved for future use)
5 – “Full Duplex” specific for remote units (Reserved for future use)
6 – “Full Duplex” specific for base unit (Reserved for future use)
7 – “TRMB Receiver” (used with GMSK modulation, not supported)
8 – “TRMB Transmitter” (used with GMSK modulation, not supported)
9 – Reserved for future use
10 – “Repeater” (ArWest Proprietary protocol)
11 – “TRMB Repeater” (used with GMSK modulation, not supported)
12 – “Transparent w/EOT” Receiver (used with GMSK modulation, not supported)
13 – “Transparent w/EOT” Transmitter (used with GMSK modulation, not supported)
RTR 0 – No Retransmission in the wireless cluster
1 – There is Repeater
MOD 1 – DBPSK
2 – DQPSK, a default settings
3 – D8PSK
4 – D16QAM
5 – GMSK
6 – 4FSK
PWRB /
PWRW
0 – Automatic Transmit Power control, a default setting for Remote units
(15 – 30) / (30 – 1000) – RF output Power in dBm / mW
CHAN Selects the frequency channel, CN = (1 – ((Maximum_frequency –
Minimum_frequency) / 6.25 + 1)).
The CN = 0 is reserved to set the Frequency Automatic scanning mode. The LINK
CHAN 0 command also forces the radio modem to continue scanning starting from the
channel currently selected by automatic scanning algorithm.
In Automatic scanning mode, to check the frequency channel currently used or scanned,
the STATE command must be used (see section 6.5.2).
FHOP (1 – 32) – Frequency Hoping Pattern number
SCRAM 0 – No Scrambling (a default setting)
(1 – 255) – Seed for Pseudo-Random Sequence Generator
