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.
Steam mode Outputs data countinuouslly and can be used for printing data.
Command mode Controls the scale using commads from a computer.
Set the parameters for the "Baud rate ( f4 )", " Output mode ( f5 )" and " Format
( f15 )", in the function table, in advance.
