7.printing the baud rate
8.Output interface
Users sometimes need to print out the weighing data through a printer or input it into a
computer or other external devices during using the balance.To meet the user's needs, an
RS-232C interface is installed at the rear of the balance.Connection methods:
(1)The serial connection of the electronic balance is as follows:
Balance (nine-core) Microcomputer (nine-core)
RXD(print) 2…………………………………… 3
TXD(output) 3…………………………………… 2
GND(grounded) 5…………………………………… 5
(2) ①Balance serial port baud ratge:1200 BPS；
②The data format is 10 bits, including a start bit (0), 8 data bits (ASCII code, low bit in
front), and a stop bit(1);
③No parity;
(3)Balance data output method setting:
According to the instruction,the output mode can be changed. FUN-0 is for “Continuous
output”,FUN-1 is for ‘Press output’(press ‘FUN’key once,output one tek data),FUN-2 is for
‘Timing output’.
