UHF Modem Commands

LINK

The LINK command is responsible for configuring ra-
dio's operation mode. It has parameters listed below.
Note: In parentheses is shown firmware version, which sup-
ports this parameter. If the firmware version is not specified, it
means that this parameter is supported in both versions.
LINK [Parameter Name] [Parameters List] [/?]
Parameter
Name
1 - Simplex Transceiver
2 - Simplex Transceiver
7 - Trimtalk 450S transceiver
8 - Trimtalk 450S transceiver
12 - Transparent w/EOT timeout Transceiver
13 - Transparent w/EOT timeout Transceiver
14 - STL Transceiver
15 - STL Transceiver
PROT
19 - Transparent w/EOT character Transceiver
20 - Transparent w/EOT character Transceiver
23 - TT450S(HW) Transceiver
24 - TT450S(HW) Transceiver
25 - Trimmark3 Transceiver
26 - Trimmark3 Transceiver
27 - Trimmark ||/||e Transceiver
28 - Trimmark ||/||e Transceiver
0 - Auto Detect (Base or Repeater)
RTR 1 - Receive from Repeater
2 - Receive from Base
1- DBPSK
2 - DQPSK, a default settings
3 - D8PSK
MOD
4 - D16QAM
5 - GMSK
6 - 4FSK
0 - 25 kHz (12.5 kHz for Trimmark3 protocol) =
9600 symbols/s
1 - 12.5 kHz = 4800 symbols/s
SPACE 2 - 6.25 kHz = 2400 symbols/s
3 - 20 kHz = 7500 symbols/s
4 - 25 kHz = 19200 symbols/s (available for Trim-
mark3 protocol only)
FHOP (only for (0 - 32) - Frequency Hoping Pattern number
firmware ver. LINK FHOP command can be processed only if
1.8) the Channel Map (up to 32 channels)
0 - No Scrambling (a default setting)
SCRAM (1 - 255) - Seed for Pseudo-Random Sequence
Generator
0 - Disable Forward Error Correction (FEC), a
FEC default setting
1 - Enable Reed-Solomon encoding

Parameter List
Parameter
Name
1 - Enable 4FSK clock correction
CLKCORR
0 - Disable 4FSK clock correction
0 - active AGC signal finding algorithm
1 - HIGH sensitivity level, -70...-117 dBm
SNST 2 - MIDDLE sensitivity level, -40...-90 dBm
3 - LOW sensitivity level -10...-60 dBm
4 - Keep last successfully received packet state
0 - default value = 4 sec.
SYNRT 1 - do not reset the LNA and ADC gain
N - Set Demodulator reset in sec
sets/gets the compatibility with:
0 - Satel 3AS
CMPT
1 - Satel Easy
2 - ADL
Note: The frequency defined by CHAN parameter is not val-
id if Frequency Hoping mode is selected. In the Frequency Hop-
ing mode, the Frequency Pattern generator must generate the
random numbers smaller than the number of frequencies listed
in the unit's frequency list.

Serial Interfacing Commands

DPORT

The DPORT is an object that responsible for data port
interface configurations like Bit Rate, Flow Control, etc.
