The second digital output mode is digital output bridge reading with temperature. It will be transmitted as a 3-data-

byte packet. The temperature byte represents an 8-bit temperature quantity, spanning from -50 to 150°C.

The EEPROM transmission occurs in a packet with 14 data bytes, as shown below.

There is a variable idle time between packets, which varies with the update rate setting in the EEPROM.
