TMP119EVM: software usage questions

Part Number: TMP119EVM

Tool/software:

I loaded the Windows version for offline use, and it seems to run OK, but I see things like Poling Rate, Device Rate, and have no clue what they mean! How do they effect the rate at which measurements are returned? There is nothing describing these, and other available settings, in the User's Guide or the datasheet! Another example is the General Call Reset button; what the heck does that do? Is there another document somewhere that describes these things?

    Polling Rate: The rate at which the the GUI queries the sensor for data. The sensor will tolerate requests for data when there is nothing new to report; it will simply report the last measurement. 

    Device Rate: Corresponds to the Conversion Rate/Conversion Cycle Time bits in the Configuration Register of the sensor. Changes made to this drop-down control on the Data tab of the GUI will be reflected in the Conversion Cycle bits of the CONFIG register on the Register Map tab and vice versa. 

    General Call Reset: General call address is described by the I2C and SMBus standards as a reserved address used to communicate with all devices on the bus. Reset is one of the defined commands that may follow the general call address, and often times the only general call command supported by a device. In this case, reset simply means the sensor will clear its digital logic and begin operating as if it just powered-on.

    thanks,
