12-2. Change of RS-232C communication Protocol
Select the communication Protocol with the setting of Function F-39.
As for the default, [Communication Protocol 1] has selected.
12-3. Explanation when Communication Protocol 1 is selected. (F-39=0 is selected.)

commuication with the following procedures.
(2) Stream mode
When the RS-232C is used, this mode keeps on outpputting the latest data of the output selected
with the Function F-41. However, the output frequency may change by setting the display
freqyency and baud rate.
(3) Synchronous with print
When the RS-232C is used, the data of output seleted with the Function F-41 is output
synchronizing with the print signal ( key, external control input and automatic print).
