Chapter 327www.javad.com COMMAND LINE INTERFACEThe built-in user-friendly Command Line Interface (CLI) allows user to perform a full configuration ofthe unit and read the statistics and alarm status. It is the most powerful tool to configure the unit. It makeschanges 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 configurationparameters that could be changed through the CLI are:• Data Port Settings- Baud Rate- Data Bits (8, 7)- Parity (Odd, Even, None)- Flow control (None or RTS/CTS)• Alarm Settings• Radio Operation Modes• Sleep modes- 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 beforeNote: The unit’s configuration that is set or modified through the CLI will be lost after unit’s reboot, unless thesaving 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 InterfaceCommand Line Interface Convention28 www.javad.com1. Command Line Interface ConventionThe following convention is implemented in HPT225BT 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 3for description), if Echo Off is selected, otherwise the error message is displayed.• A successfully performed command is replied by @00 code, if Echo Off is selected, otherwise theset value is replied.• A command with the certain [Parameter Name] and blank [Parameter List] displays the currentsettings for a given parameter.• To set the mode ordered by CLI commands as permanent User Setting (the setting automaticallyselected for the boot-up unit) the SAVE command must be asserted.• A command followed by “/F” option displays the Parameters in the predefined frame format. Thedisplay frame format is unique for each command supporting “/F” option.Table 1. Command Line Interface Error Codes1.1. Software Switching to Command ModeOn power-up the radio modem is in data-mode. To switch to command mode the special byte-sequenceswith special meanings are used:• Escape-Sequence: “+++” with 20 ms guard time before and after the command characters• Escape-Acknowledge: “@00<CR><LF>”20 ms toggling on CTS control line needed to acknowledge switching from Data to Command mode andvice versa.Error Code Short Description0x01 Command Syntax Error. A command followed by “/?” displays a command usage.0x02 The parameter has a format error. A command with the certain [Parameter Name] followed 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 commands, the HELP command must be used.0x05 Unspecified Error
Command Line InterfaceCommand Line Interface Convention29www.javad.com Happy Flow1. In data-mode the unit starts looking for the Escape-sequence if there is no data from DTE (DataTerminal Equipment) for more than 20 ms (Start Guard Time).2. If the unit detects the Escape-Sequence:• The transmitter continues sending over the air the data received from DTE before Escape-Sequence and buffers the data from DTE;• The Receiver immediately stops forwarding to DTE the data received over the air and buffers itinstead.3. The radio unit waits for 20 ms and then sends Escape-Acknowledge to DTE if there is no datafrom DTE during 20 ms of Stop Guard Time.4. The unit goes to command mode and discards Escape-Sequence from input buffer. The modem isimmediately ready to receive commands. At the same time it continues buffering the data receivedover the air since step 2.Escape-Sequence in DataDuring its waiting in step 3, the unit receives data from DTE:• The unit sends buffered Escape-Sequence from DTE to the air;• The unit sends all buffered data received from the air since step 2 to DTE and stays in data-mode(i.e. transmits data received from DTE over the air – including the just received, unexpected, dataand forwards data received over the air to DTE.)1.2. Hardware Switching to Command ModeAs alternative to Software Switching, the switching through the MP/DP (Data Terminal Ready, DTR)control line can be used. To set Command Mode, the DTE must assert DTR signal active and thenpassive. By falling edge of DTR signal the unit goes to command mode and then sends Escape-Acknowledge to DTE (“@00<CR><LF>”).20 ms toggling on CTS control line needed to acknowledge switching from Data to Command mode andvice versa.Note: The powered up radio modem by default goes to Data Mode regardless of DTR control line polarity.1.3. Switching to Data Mode• DTE sends the CLI command “DATAMODE<CR><LF>” to the unit.• Unit answers with Escape-Acknowledge („@00<CR><LF>“) and immediately goes to datamode,so that the DTE can start sending data as soon as the Escape-Acknowledge has been received.• If no valid CLI commands received from DTE within 1 minute, the unit will automatically switchback to data-mode.
