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
Parameter List
CHAN
Sets/gets the current frequency channel num-
ber. Up to 32 channels are available in the
channel map (example LINK CHAN 24).
Refer to MAP command about creating and
modifying the channel map.
SIGTYPE
Sets/gets the signal type
1 - 100 bps
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
Parameter List
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.

Name
Parameter List
MODE
Sets/gets the scanning mode
0 – Manual
1 – Automatic
Refer to “Beacon scanning modes” for scan-
ning modes description.
FREQ
Sets/gets the frequency scanning criterion
1 – Full range scanning with 500 Hz step
2 – Channel map scanning
Parameter FREQ is available for Automatic
scanning mode only.
SIGTYPE
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
4 – All signal types (200 bps, 100 bps, 50 bps)
are scanned
Parameter SIGTYPE is available for Automatic
scanning mode only.
ALMANAC
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
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
