Description and Operation

INTRODUCTION

Marine Radiobeacon receiver (283.5 to 325 kHz) or Beacon receiver complies with Broadcast Standard for the USCG DGPS Navigation Service COMDTINST M16577.1. Beacon receiver is designed to receive pseudorange corrections transmitting by Radiobeacon stations. Maritime Radiobeacon DGNSS systems according to RTCM SC-104 version 2.3 are usually capable of broadcasting the following RTCM messages: 1, 2, 3, 5, 6, 7, 9, 15 (sel-dom), and 16. Radiobeacons are widely used throughout the world.
GNSS Radiobeacon transmissions meet stringent integrity and reliability requirements mandated by the International Association of Lighthouse Authorities.
The delivered product is a wireless system, which includes:

• Beacon Receiver – Beacon receiver OEM board;
•  AWLaunch – Windows based Unit Configuration and Maintenance Software Application running on a IBM PC compatible computer and connecting to the device over RS-232 interface or USB- to-Serial adapter. The setting can be done through the built-in Command Line interface (CLI), or through the configuration and maintenance application software running either on PC – AWLaunch.

The diagnostic feature of the Beacon Receiver system provides the information to monitor and maintain user’s communications link. The product is designed for maximum performance and reliability even in the hardest environments. Plug and play at its best, robust, withstanding the most adverse of conditions.

Media Access Control (MAC)
The following Media Access protocols are available for Beacon OEM Receiver modem:

1. Beacon protocols
2.  Sleep mode1 is an investment provided by MAC sub-layer that provides additional power saving. The wakeup from Sleep mode is user selectable either by an internal real-time clock, or by an external controller through the data interface control lines (RTS or DTR), or by SLEEP input line (CMOS/TTL compatible input lines).

Management Tools
The built-in management tools along with AWLaunch (configuration and monitoring software application) will provide the following benefits: Easy user’s interface for system configuration and monitoring using well developed CLI or intui- tive GUI. An ability to monitor status, alarms and radio performance through the intuitive GUI. Software upgrades and improvements can be downloaded from AWLaunch to the units connected with PC/PDA.

COMMAND LINE INTERFACE

The built-in user-friendly Command Line Interface (CLI) allows user to perform a full configuration of the unit and read the statistics and alarm status. It is the most powerful tool to configure the unit. It makes changes to all possible settings that system will not be able to determine automatically.
The CLI commands allow user to configure and reconfigure the unit’s settings. The user configuration parameters that could be changed through the CLI are:

•  Data Port Settings
  • Baud Rate
  •  Flow control (None or RTS/CTS)
  •  Stop bits
•  Alarm Settings1
•  Radio operation modes
•  Scanning modes
•  Sleep modes2
  •  On/Off
  •  Activate by internal real-time clock
  •  Activate through RTS/CTS lines
  •  Activate by external sense lines
  •  Activate by any combination of the parameters mentioned before

Note : The unit’s configuration that is set or modified through the CLI will be lost after unit’s reboot, unless the saving operation is used to store a new setting in the unit’s configuration file. The CLI commands also provide filing operations, which include:

•  Downloading
  • Unit’s Configuration files
  •  Software Images
•  Uploading Unit’s Configuration files
•  Saving into the configuration files the configuration parameters modified through the CLI.

Command Line Interface Convention

The following convention is implemented in Beacon Receiver Command Line Interface (CLI):

• The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a command delimiter.
•  The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a reply delimiter followed by the “CLI>”
•  prompt if Echo option is On.
•  The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a reply delimiter if Echo option is Off
•  (default option).
•  The 2-digit number followed by “@” in the unit’s reply indicates the error code (refer to Table 3-
•  1 for description).
•  A successfully performed command is replied by @00 code for both Echo ON and OFF modes.
•  A command with the certain [Parameter Name] and blank [Parameter List] displays the current settings for a given parameter.
•  To set the mode ordered by CLI commands as permanent User Setting (the setting automatically selected for the boot-up unit) the SAVE command must be asserted.
•  [/?] orders to show the help information for the given command.
•  Commands are not key sensitive; small, none capital characters can be used to enter CLI commands.

usage.
0x02| The parameter has a format error. A command with the certain [Parameter Name] fol- lowed by “/
?”| displays the format and range of the variable.
0x03| The parameter is out of allowed range. A command with the certain [Parameter Name] followed by “/?” displays the format and range of the variable.

0x04

| The command is not valid for specific radio model. To display the list of available com- mands,the HELP command must be used (see “Software Switching to Maintenance Mode” ).
0x05| Unspecified Error

SOFTWARE SWITCHING TO MAINTENANCE MODE
To switch to Maintenance mode the special byte-sequences with special meanings are used:

•  Escape-Sequence: “+++” with 20 ms guard time before and after the command characters
•  Escape-Acknowledge: “@00” 20 ms toggling on CTS control line needed to acknowledge switch-ing from Data to Maintenance mode and vice versa. In Maintenance mode, the unit’s serial port must keep CTS line always active.

Happy Flow

1.  In data-mode the unit starts looking for the Escape-sequence if there is no data from DTE for more than 20 ms (Start Guard Time).

2. If the unit detects the Escape-Sequence:
   The Receiver immediately stops forwarding to DTE the data received over the air and buffers it instead.

3.  The radio unit waits for 20 ms and then sends Escape-Acknowledge to DTE if there is no data from DTE during 20 ms of Stop Guard Time.

4.  The unit goes to Maintenance mode and discards Escape-Sequence from input buffer. The modem is immediately ready to receive commands. At the same time it continues buffering the data received over the air since step 2.

HARDWARE SWITCHING TO MAINTENANCE MODE
As alternative to Software Switching, the switching through the MP/DP control line can be used (this control line can be also used as Data Terminal Ready, DTR). To set Maintenance mode, the DTE must assert DTR signal active (0v level). By falling edge of DTR signal the unit goes to Maintenance mode and then sends Escape-Acknowledge to DTE („@00“).
20 ms toggling on CTS control line followed by Escape-Acknowledge response is needed to acknowledge switching from Data to Maintenance mode and vice versa. In Maintenance Mode, the unit’s serial port must keep Clear to Send (CTS) line always active.

Note : The powered up radio modem always goes to data mode.

SWITCHING TO DATA MODE

• DTE sends the CLI command „DATAMODE“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.
