Communication ModesCommunication Modes
Communication Modes
There are the following modes.
Stream Mode
The data is output at every display update. If the data can not be output completely
due to a slow baud rate, the data is output at the next update.
Auto Print Mode
The data is printed at batch finish and recipe finish automatically.
Manual Print Mode
When the preset print key is pressed or terminal is connected, data is output.
Total Print Mode
When accumulating it or canceling the last result, the results of batch finish and recipe
finish are printed. When canceling the last results, the inverse polarity data is output.
