Switching To Data Mode; Networking Commands; Link; Map - Javad Beacon User Manual

SWITCHING TO DATA MODE

• DTE sends the CLI command „DATAMODE<CR><LF>"to the unit.
• Unit immediately goes to data mode without Escape Acknowledge.
• If no valid CLI commands received from DTE within 1 minute, the unit will automatically switch back to
data-mode.
Note: The data received over the air could be lost due to Rx buffer overflow if the unit stays in Maintenance mode longer than
15 seconds.

Networking Commands

LINK

The LINK command is responsible for configuring ra-
dio's operation mode. It has parameters listed below.
LINK [Parameter Name] [Parameters List] [/?]
Parameter
Name
Sets/gets the current frequency channel num-
ber. Up to 32 channels are available in the
CHAN channel map (example LINK CHAN 24).
Refer to MAP command about creating and
modifying the channel map.
Sets/gets the signal type
1 - 100 bps
SIGTYPE
2 - 200 bps
3 - 50 bps

MAP

The MAP command is used to create, modify and save
the frequency channel map of the Beacon receiver.
MAP [C<Parameter>][F<Parameter>][SAVE]
Parameter
Name
C Channel number (1- 32)
F Carrier frequency in Hz
SAVE Saves the channel map
The MAP command without parameters displays the
channel map of the active receiver.:
Example:
MAP c1 F314000 - sets the 314 kHz frequency
to channel number 1;
MAP SAVE - saves the channel map.

SCAN

The SCAN command is used to set/configure scan-
ning modes. For Automatic scanning mode it is possi-
ble to select the Frequency scanning and Signal type
scanning criteria.
SCAN [Parameter Name] [Parameters List]
14
Parameter List
Parameter List
[/?]
Parameter
Name
Sets/gets the scanning mode
0 – Manual
MODE 1 – Automatic
Refer to "Beacon scanning modes" for scan-
ning modes description.
Sets/gets the frequency scanning criterion
1 – Full range scanning with 500 Hz step
FREQ 2 – Channel map scanning
Parameter FREQ is available for Automatic
scanning mode only.
Sets/gets the signal type scanning mode
1 – 100 bps signals are scanned
2 – 200 bps signals are scanned
3 – 50 bps signals are scanned
SIGTYPE
4 – All signal types (200 bps, 100 bps, 50 bps)
are scanned
Parameter SIGTYPE is available for Automatic
scanning mode only.
Returns the Almanac table of available Beacon
reference stations scanned by second (Slave)
Beacon receiver. Each line of the table contains
information (Frequency, RSSI, Signal type, Ref-
erence station ID) about one Beacon reference
ALMANAC
station. The following is the structure of the Al-
manac table's line:
<Frequency in Hz> <TAB> <RSSI in dBm> <TAB>
<Signal type> <TAB> <REF
Station ID> <CR> <LF>

BEACON SCANNING MODES

Beacon has the following two scanning modes:
1. Automatic (searching Beacon reference stations)
In this mode two independent Beacon channels start
cooperative searching of Beacon reference stations
using the selected criteria in 1.1 and 1.2. Each found
reference station is recorded in the
Almanac table where the following parameters of
found station are specified: frequency, signal type,
RSSI and Reference station ID. The RSSI parameter
is recorded to determine the station providing the
best RTCM signal. If no Beacon reference station is
