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
