1. Introduction

This document describes how to convert from a RS485 system to a RS232 system and vice-versa. This will need to be done when uploading new firmware through ANB Sensors Data Retrieval Unit.

2. RS485 – RS232

  1. Using your RS485 interface enter RS232!
  2. You will see a message explaining that the change will not take place until the unit is powered down
  3. You are now ready to use your system as a RS232 interface

3. RS232 – RS485

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

  1. Plug the Data Retrieval Unit (DRU) into the USB port of a computer ensuring the S1100 is disconnected from the DRU
  2. Launch Tera Term
  3. On Set-up menu select serial port from the drop down. In the resulting window select the correct com port
  4. Select speed = 9600, Data = 8bit, Parity = none, Stop bits = 1, flow control = none. Click OK
  5. On Set-up menu select terminal and new line options in resulting window should be Receive = Auto and Transmit = CR
  6. Ensuring the sensor is dry and disconnected from power, plug the DRU connector to the subconn connector on the S1100
  7. Wait for the system to beep once, the sensor is now ready to operate
  8. Enter RS485!
  9. Disconnect sensor from DRU, you can now re-install the sensor into your RS485 system
