16. RS-232C Serial Interface
Note When the RS-232C serial interface is used, be sure to set the “Address ( f11 ) “ to
“( 00 )”.
RS-232C interface has the following two modes.
Stream mode Outputs data continuously and can be used to print data.
Command mode Controls the scale using commands from a computer.
To use RS-232C interface, set the parameters of the “Baud rate ( f4 )”, “ Output
mode ( f5 )”, “ Format ( f15 )” in the function table.
Optional cables are available as follows:
AX-KO577A-200 RS-232C cable, D-sub 25 pin, 2 m
AX-KO1786-200 RS-232C cable, D-sub 9 pin, 2 m
