23 RS232 interface features
1. General features
The balance transmits the value visualized on the display following serial RS232C
standard, allowing to print the value of weight to a PC monitor or to a serial printer. In
the case of connection to a PC, it will be possible to select the transmission in
continuous mode or transmission at user command through pressing of the
button (as described at pag.17). The balance is also capable of receiving commands,
always through the standard RS232C, that allow performing all the functions
available through the keyboard of PC itself. The speed of transmission and reception
can be selected, as described previously (pag.19), to 1200, 2400, 4800, e 9600 baud.
The character format is of 8 bit preceded by one bit of start and followed by a bit of
stop. Parity is not considered.
2. Selection of interface for PC
Selecting the transmission to PC (personal computer IBM compatible), it is
achieved a continuous transmission output, at the same rate of weight update on
display of the balance. It is possible to perform all the functions of the balances
directly from the computer keyboard, transmitting to the balance the ASCII codes
as in the table below. The connector to use for connection to PC is the number 1
(fig.1 pag.49).
