Temporarily Set iSIC Logger Secondary Baud Rate

The iChart software contains a terminal emulator used to communicate with sensors via serial output. Follow the process below to temporarily change the terminal, or secondary, baud rate to communicate with a wide range of sensors through an iSIC data logger.

WARNING: This procedure should only be conducted while in direct connection with the iSIC data logger. NexSens does not recommend attempting this procedure remotely.

 

1. Connect to the iSIC data logger by clicking Advanced | iSIC | iSIC and inserting the proper connection credentials in the iSIC Setup interface. Once completed, click Connect.

 

2. Once connected, choose the iSIC Command tab.

 

 

3. Click the drop down menu next to Command and search for SETSUARTBAUD.
   1. Ensure the description of the command states Temporary set secondary COM baud. 

 

4. Follow the highlighted portion of the image below to send the proper argument. Each number 1-7 corresponds to a specific baud rate. Insert one of these numbers into the space beside Argument to temporarily change the baud rate of the terminal to match the baud rate of the sensor.

 

5. Click the space beside Send and hit enter on your keyboard or click the Send button at the bottom of the interface.
   1. An ACK: should display in the result section for a successfully sent argument.

 

 

6. Once this is completed, go to Advanced | Terminal.

 

 

7. Choose the correct PC connection settings, and ensure to match the port number of the desired sensor.

 

 

8. Once inside the terminal, data should begin outputting depending on the data output configuration on the sensor.
   1. Example below:
      • Sensor: Airmar SS510
      • Baud Rate: 4800
      • Output: NMEA0183 (1-second intervals)

 

 

 

9. If random characters begin to output, then the terminal baud rate does not match that of the sensor. Review the sensor’s baud rate and repeat the steps above.

 

10. Note: The temporary baud rate will reset once power is cycled.
