INFO
The INFO command is used to retrieve the Radio ID
along with its Hardware version, the loaded real- time
software version/revision and BootLoader’s version/
revision.

ID
LMR400RX(UHFSSRX) UHF Radio Modem, Javad
GNSS Product ID =111
SN Six bytes Serial Number (SN)
HW
1.0 - hardware version in numeric “Major.Minor”
format
SW
Ver. 1.0 Rev. A - displays software’s version in
numeric “Major.Minor” format and revision in
numeric format (range from 01 to 99) for engi-
neering releases and alphabetic format (A to Z)
for manufacturing releases
BL

Software =Ver. 1.8 Rev 04 B24
BootLoader =Ver. 3.0 Rev 03
STATE
The STATE command is used to check the state of the
wireless link, the unit in the link, and the alarm con-
trol lines.
STATE [Parameter Name] [Parameters List] [/?]
Parameter
Name
Parameter List
TTL1 0/1 – State of TTL_IN1 line
TTL2 0/1 – State of TTL_IN2 line
RSSI
-52 to -116 dBm – Indicates the Receive Signal
Strength in dBm
BER 1.0E-6 to 9.9E-3 – Indicates the BER level
FREQ
406.000000 to 470.000000 MHz – Displays the
central frequency of the operating channel
CHAN
1 to 9601 – Displays the selected or currently
scanned frequency channel
TEMP
-30°C to 100°C – Displays the temperature inside
of enclosure
SYNC
1 – Indicates the established link,
0 – if link is not established yet
MODE
AUTO – Indicates Automatic scanning mode
FHOP – Indicates Frequency hopping mode
FIXED – Indicates that the radio modem is work-
ing on fixed channel from channel map.

Spread Spectrum Modem Commands
LINK
The LINK command is responsible for configuring ra-
dio’s operation mode.
LINK [Parameter Name] [Parameters List] [/?]
LINK commands are as common so specific for two
bands: 902-928 MHz band and 868-870 MHz band:
Parameter
Name
Parameter List
FEC
0 – Disable Forward Error Correction (a default
setting)
1 – Enable Forward Error Correction
FHOP
(0-9) - FH Pattern numbers for USA;
(10-19) - FH Pattern numbers for Australia;
For EU parameter FHOP not applied
MOD 5 - GMSK
