9.0 RS-232
INTERFACE
The balances have the ability to send or receive data over the serial interface.
The weighing data can be sent over the interface either automatically or when the
user presses the [Print] key.
The user has control over what data is to be printed.
The following gives a description of the RS-232 interface.
9.1 HARDWARE
The RS-232 interface is a simple 3 wire connection. The input and output
connections are:
Connector: 9 pin D-sub miniature socket
Pin 2 input to balance RXD
Pin 3 output from balance TXD
Pin 5 Signal ground GND
Handshaking is not applied.
Baud rate: 4800, 9600, 19200, 38400
Parity: NONE (=8N1), EVEN (=8E1) or ODD (=8 O 1)
All lines are terminated with carriage return and line feed (<CR><LF>).
In continuous output mode, or if single-line output on demand is selected, the serial
output format will be a single line in the form “1234.567 g<CR><LF>”.
The format of the single-line output will change depending on the mode in which
the balance is operating, as described below.
