Specifications

101
To set up the console connect a serial cable to the 9-pin female plug on the electronics
unit and to your terminal or PC. The terminal or terminal-emulation program and serial port
should be configured as follows:
• Line feeds should be added to incoming carriage returns.
• Local echo should be turned off.
• Terminal mode is not critical, as the console uses no special formatting.
• RS232 interface
• 9600 baud
• 8 data bits, 1 start bit, 1 stop bit
• no parity, no flow control
5.11.4 Commands
Once the link has been established commands may be entered and messages can be received.
User commands are entered as lower-case words without any spaces. For example,
setconfig<enter> allows the user to set the buoy configuration. The following commands
will not be recognized, set config or Setconfig. It is important that the command is
entered as-one without the use of <del> or <backspace>. All output generated by the
console is in normal human-readable form, except in RXD-mode.
Table 5.11.1 gives an overview of all available commands in alphabetical order. The list
contains commands for configuration setting and checking and commands for trouble shooting.
5.11.5 Example setbat
In case the electronics unit has to be replaced, take the following steps to correctly transfer the
energy count from the old unit to the new unit.
• See subsection 5.11.4 for setting up the console.
• Connect the electronics unit’s serial port to a PC.
• If the buoy is still switched on, send the status <enter> command.
• The electronics unit will respond amongst other with the remaining capacity of the
batteries. Write down the remaining energy.
• If the buoy has been switched off previously, connect the electronics unit’s serial port to
a PC after setting up the console.
• Apply power to the electronics unit by connecting the buoy’s cable or an external DC
power source.
• Wait until the electronics unit finishes its start-up procedure (about 10 seconds).
• Now you can enter the status<enter> command. Write down the remaining energy.
• Now you can replace the electronics unit.
• To set the proper battery capacity, connect the electronics unit’s serial port to a PC, start
the proper program and apply power to the electronics unit, either by connecting the
buoy cable or applying an external DC power source.
• Wait until the unit finishes its startup procedure.
• Enter the setbat<enter> command.
• The unit will ask for number of batteries and capacity (Wh) per battery. Enter 1 for the
number of batteries, enter the value written down in the previous step (remaining
energy) for the capacity per battery.
• After entering the battery setup, enter y <enter> to store the new settings in memory.
• Reset the unit by entering reset<enter>.
• The buoy will restart and print the installed battery capacity. This should amount to the
product of the numbers of batteries and the watt hours per battery entered.
