1. Introduction

This document describes how to perform the firmware update procedure.

To update the firmware, the system needs to have a RS232 interface. If your system currently runs with a RS485 interface, it needs to be converted Instructions on how to do this can be found here.

ANB Sensors firmware update will always comprise the interface and driver firmware which has to be uploaded together.

Follow the procedures outlined below to ensure complete compatibility of the two systems.

2. Set-up

THE SENSOR SHOULD NOT BE COLLECTING DATA WHEN CONNECTED TO THE DATA RETRIEVAL UNIT

  1. Install Tera Term before using the S1100 https://osdn.net/projects/ttssh2/releases/
  2. Plug the Data Retrieval Unit (DRU) into the USB port of a computer ensuring the S1100 is disconnected from the DRU
  3. The first time the DRU is plugged into the computer it is possible that the computer will need to download a driver automatically from the internet.
    • Therefore, if this is the first time the DRU is plugged in, ensure you have an internet connection
    • You can confirm that a driver is installed after plugging in the DRU, by going to ‘Control Panel’ > ‘Device Manager’ In the list under Ports (COM & LPT) will be an entry USB Serial Port (COMn) where ‘n’ will be the COM number you select in Tera Term
    • Tera Term will not be able to communicate with the sensor if a driver has not been installed
  4. Launch Tera Term
  5. On Set-up menu select serial port from the drop down. In the resulting window select the correct com port
  6. Select speed = 19200, Data = 8bit, Parity = none, Stop bits = 1, flow control = xon/xoff
  7. Transmit delay set to 0 sec/char and 30 msec/line, click OK
  8. On Set-up menu select terminal
  9. New line options in resulting window should be Receive = CR+LF and Transmit = CR+LF, click OK
  10. Turn on CAPS LOCK
  11. Holding down the U key and ensuring the sensor is dry and disconnected from power, plug the DRU connector to the subconn connector. (Note: This should be done simultaneously)
  12. The monitor will display a version number and a ‘>’ symbol

3. Upload Interface Firmware

  1. Release CAPS LOCK key and type pf [ENTER]
  2. The monitor will display ‘pf+’
  3. On tera term go to file > send file
  4. Browse to where firmware update has been saved and click ‘open’
  5. The update progress to the system is indicated by ‘.*.*.*.’ which will continue until the update is complete
  6. At completion the upload will have been successful if the last character displayed is a ‘+’ symbol
  7. If no ‘+’ sign is displayed, disconnect sensor from DRU and repeat Set-Up and Driver firmware update sections
  8. If no ‘+’ sign persists after repeating the procedures please contact your ANB Sensors representative
  9. Disconnect S1100 from the DRU and prepare the sensor for the driver firmware update by repeating the ‘Set-Up’ procedure

4. Uploading Driver Firmware

  1. Release CAPS LOCK key and press t [ENTER]
  2. The monitor will display an instruction to press the U key.
  3. Turn CAPS LOCK on and press the U key
  4. The monitor will display a version number and a ‘>’ symbol
  5. Release CAPS LOCK key and type pf [ENTER]
  6. The monitor will display ‘pf+’
  7. On tera term go to file > send file
  8. Browse to where firmware update has been saved and click ‘open’
  9. The update progress to the system is indicated by ‘.*.*.*.’ which will continue until the update is complete
  10. At completion the upload will have been successful if the last character displayed is a ‘+’ symbol
  11. If no ‘+’ symbol is displayed, disconnect sensor from DRU and repeat Set-Up and Driver firmware update sections
  12. If no ‘+’ symbol persists after repeating the procedures please contact your ANB Sensors representative
  13. Disconnect S1100 from the DRU and power normally
  14. If required, convert back to RS485. Instructions to do this can be found here
