16. RS-232C Serial Interface
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
