Yaohua Weighing System XK3190-C601 - Instruction Table Is Listed in Appendix

4
Indicator will act according to instruction from computer,
please refer to following notes and table:
AD: address of indicator (example A in ASCII code 41);
NN: address of memory pc wants to read/write;
C1: Content pc wants to read/write (000 digit);
C2: Content pc wants to read/write (00 digit);
C3: Content pc wants to read/writ (0 digit);
XH: Verify result for high 4 digits;
XL: Verify result for low 4 digits;
Notes:
• Address indicator could set is from 1~26, while
communication address is corresponding from A~Z;
• Instruction from A~Z is transferred in ASCII code;
but the example listed in table is in Hex. code. When
communicating with PC via the hyper terminal software(This
software is with windows operating system),you should
choose “transmit in hex format”, or else you must convert
the example to ASCII code;
• Instruction Q,R,S,T U is read/write operation for
data memory. There are many strings in data memory, but
one instruction from pc only triggers one operation, hence
several instructions should be sent from pc one by one
to do these operations

• Connect indictor to scoreboard via 20mA current
loop output;
Data is transmitted serially in binary code with baud rate 600.
Data format is as listed below (one group):
0 1 2 3 4 5 6 7 8 9 10
START DATA(Low is prior to high) SIGN STOP
Indicator sends one frame data to scoreboard per 100ms, one
frame consists of 3 groups while the data format of one group
is as listed above. Below is the content for one frame:
0 1 2 3 4 5 6 7 8 9 10

For group one, Sign bit is 0; X(D0,D1,D2)means decimal point
(0~3); Y（D3）means sign(1 for negative while 0 for positive);
Y (D4) means display weight type( 1 for net weight while 0 for
tare weight); G17 and G16 is binary code;
For group two, Sign bit is 0; G15~G8 is binary code;
