Weight calibrating

  (1)power on, on zero situation, long press "M" around 5 seconds, enter the option interface. window shows: "-----" (if press "M" to quit)

  (2)press "T", enter the single point calibration interface, window shows: "CAL" around 1 seconds, shows calibrate the weight of the weight . (such as:10000)

  (3)press "T", choose modification, press "0", current figure plus 1 ,press "M" to confirm.window shows: "Put" around 1second, shows the internal code.

  (4)If the internal code is not zero,press "0", put corresponding weights until stable, press "M". window shows: " PASS" around 2 seconds, finish calibrating, and back to weighing state.

Parameter setting

 (1)power on, on zero situation, long press "M" around 5 seconds, enter the option interface.window shows: "-----" (if press "M" to quit)

  (2)press "0" to enter parameter setting,window shows: "STEP-1" ,around 1 seconds, will enter next step automatically.

          window shows measuring range: such as "30000"

  (3)press "T" to choose modification, press "0",current figure plus 1,press "M" to confirm. window shows: "STEP-2", around 1 seconds, will enter next step automatically.window shows division value:such as: 5

  (4)press "0" to modify the division vlue (1,2,5,10,20,50); press "M" to confirm. indow shows: "STEP- 3", around 1 seconds, will enter next step automatically.          window shows weight decimal point: such as: " 0.000"

  (5)press "0" to modify decimal point (0  0.0  0.00  0.000  0.0000); press "M" to confirm.

          window shows: "STEP- 4", around 1 seconds, will enter next step automatically.

          window shows zero tracking range: such as: " 1d"

  (6)press "0" to modify zero tracking range:choose 0.5d; press "M" to confirm.

          window shows: "STEP- 5", around 1 seconds, will enter next step automatically.         window shows serial mode: such as : 3

(7)press "0 " to modify transmit mode (0,1,2,3); press "M" to confirm.

          window shows:  "End" ,around 1 second, back to weighing state.

Serial communication protocol

1. Communication protocol:   

1. 9600 Kbps,  8-digit figures,  1-digit stop bit, none parity bit.

2. cash register scales send to weighing scales :0x50

2.   weighing scales return the following data:

communication data format:

begining (3byte) weighing data location    weighing data        ending (3bytes)hex

               hex  (2bytes) hex              (5bytes)          (3bytes) hex      

               0x02  0x20  0x20          xxxxx              0x20  0x4b 0x47

weighing data:ACS code, decimal point also according to ACS.

Such as 1:

if weight is :12.34

0x02 0x20 0x20 0x31 0x32 0x2e 0x33 0x34 0x20 0x4b 0x47

Such as 2:

if weight is :1.234

0x02 0x20 0x20 0x31 0x2e 0x32 0x33 0x34 0x20 0x4b 0x47

transmit mode:Dahua :ACS port 1-4. Aclas port 5-7, need debugging according to different software.

   Serial communication protocol

Transmit mode:

0.: none transmission

1.: continuous transmission (weight, unit price, sum)

2.: stable transmission (weight, unit price, sum)

3.: transmit response (weight ) (default)

4.: stable transmission (weight)

5.: initiative transmission (Aclas OS2)

6.: passive transmission (Aclas OS2)

7.: Aclas DigitOpBox protocol
