16 RS-232C Serial Data Interface
Stream mode Outputs data countinuously and can be used for printing data. Command mode Controls the scale using commands from a computer.
It is necessary to set the parameters of the “Baud rate ( f4 )”,
”Output mode ( f5 )”, “Format ( f15 )” in the function table in advance.
There are option cables as follows:
