TREAMING

 

This command enables the JDx sensor to continuously transmit data out to the RS-485 bus at the bandwidth specified in 
section 3.2.5.  A value of 0 or 1 must be provided.  The value of 0 turns off data streaming, while the value 1 enables data 
streaming.  This command is useful if the user wishes to not actively interrogate the JDx sensor for samples.  Care should be 
taken using this command when the JDx sensor is installed on a shared RS-485 bus.

Note 

A Non-Volatile Save command is required to save the streaming setting to non-volatile 
memory.  This will ensure the parameter is recalled after a power cycle.  Responses to the 
commands are the same as the responses to the Get Value command.  
Changing the baud or the output data rate of the device may interrupt the stream.  If this 
occurs, simply re-issue the command to start streaming with the new settings.
