G7-G0: binary system data
G0-G17: 18 digits binary weighing sign from low to high
4. The indicator is able to connect with the matched display screen by standard RS232.
But the reconnection is required. To the 5 pins plug, connect feet 2 with feet 3, to the
15 pin plug, connect feet 9 with feet 11, and connect feet 10 with feet 12. Please refer
to the chart below after reconnection.

5. Serial communication interface
Serial interface should be connected with pc in a right way. Otherwise damage occurs
to the indicator terminal or pc's even worse damages the indicator and pc.
Computer skill and programmer ability are required by computer operation. Only
qualified personnel are allowed to service this equipment.
i.
Load cell D2002E type realize data transmission between pc and indicator by
serial interface. The transmission is continuous, baudrate 600, 1200, 2400,
9600bps are optional. 15 pins plug is used to connect serial interface and display
terminal. Please refer to chart 2-5 for detailed information on Feet 1, 2 (RS232). It
is better to put the shield into earth at the PC terminal.
ii.
Three communication modes
Mode 1: data is ASCII code, each byte includes 10 digits. Digit 1 is the start bit, digit
10 is the stop bit, and the middle 8 digits are data bit. Each rule digit includes 8 bits
including decimal. Data transmit from low to high, each data rule is separated by " =".
The display shows the weighing sign. Take 188.5 for example, continuous transmission
5.88100=5.88100=....... When the digit is –1885, transmission .58810=.58810=......
Mode 2:
Each byte includes 10 digits. Bit 1 is the start bit, bit 10 is the stop bit, and the middle 8
bits are data bit. Each rule digit includes 18 bits.
