aXLOADOS! command

aXLOADOS! is an example of an SDI-12 transparent mode command. It is used to send an operating system (OS) update from a data logger to an SDI-12 sensor.

NOTE:

Verify with the sensor manufacturer that the sensor supports this command.

Use aXLOADOS! in the following procedure to send an OS update to an SDI-12 sensor.

  1. Supply power to the data logger. If connecting via USB for the first time, you must first install USB drivers by using Device Configuration Utility (select your data logger, then on the main page, click Install USB Driver). Alternatively, you can install the USB drivers using EZ Setup. A USB connection supplies 5 V power (as well as a communications link), which is adequate for setup, but a 12 V battery will be needed for field deployment.

  2. Physically connect your data logger to your computer using a USB cable, then in ClosedDevice Configuration Utility Software tool used to set up data loggers and peripherals, and to configure PakBus settings before those devices are deployed in the field and/or added to networks. Also called DevConfig. select your data logger.

  3. Copy the sensor OS file from the computer to the data logger.

    1. Select File Control > CPU: drive > Send and navigate to the file on the computer.

    2. Click Open.

    3. Click OK.

  4. Enter the transparent mode as described in SDI-12 transparent mode.

  5. An Entering SDI12 Terminal response indicates that SDI-12 transparent mode is active and ready to transmit SDI-12 commands and display responses.

    The load OS command has the following format:

    aXLOADOS Baudrate drive:filename!.

    For example: 0XLOADOS 9600 CPU:0XF5BA.MOT!.

    Type the command, including the ending exclamation point (!) then press Enter.

  6. The screen will show OS send updates and the bytes sent will continue to increase. The process is slow, it can take several minutes, but not hours.

  7. A SUCCESS message indicates the process is complete.
