16. RS-232C Serial Interface
Note When the RS-232C serial interface is used, be sure to set the "Address ( f11 ) " to "( 00 )".
The RS-232C interface has the following two modes.
Stream mode Outputs data continuously and can be used for printing data.
Command mode Controls the scale using commands from a computer.
Set the parameters for the "Baud rate ( f4 )", " Output mode ( f5 )" and " Format
( f15 )", in the function table, in advance.
There are option cables as follows:
AX-KO577A-200 RS-232C cable, D-sub 25 pin, 2m
