16 RS-232C Serial Data Interface
RS-232C interface has the following two modes.
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:
AX-KO557ARS-232C cable, D-sub 25 pin, 2m
AX-KO1786-200 RS-232C cable, D-sub 9 pin, 2m
