platter, you can press this key to adjust to zero.
Press this key and hold it for 1.5 seconds to turn on or turn off the backlight.
: This key is used to deduct the packing weight.
If you need to deduct the packing weight, put the container or wrapper on the scale first, and
then press this key to enter weight- deducting state. Then, take off the container and put the
commodity into the container and then place the packed goods on the pan again, now, the LCD will
display the net weight. Remove the merchandise and press this key, the scale will return to normal
weighting state.
Press this key and hold it for 1.5 seconds to enter into the unit switch function. Press the key
“ ”to shift the unit and press the key “ ” to confirm or exit the setting status.
: Press this key and hold it for 1.5 seconds to soft turn off the scale.
There is “stable” mark on the display
screen. When the weight is stable, the
triangle indicator will light which means it
is in the normal weighing status, at this
time you can put commodity on the platter

same with OP box.
sending content is as follows:
Head1:1 byte,fixed as 0x01.
Head2:1 byte,fixed as0x02.
Flag1:1 byte,status: F’: Weight is beyond the range or haven‟t startup to zero.
‘S’: Weight is stable.
‘U’: Weight is unstable.
Sign:1 byte,sign: ‘-’:Weight is negative.
‘ ’: Weight is positive.
Weight:6 bytes,weight
Unit:2 bytes,unit
CheckSum: 12 bytes in front of the vision exclusive or and.
Tail1:1 byte,fixed as 0x03.
Tail2:1 byte,fixed as 0x04.
Flag2:1 byte,status:
Bit4:1: The current weight is zero. 0:The current weight is not zero.
Bit5:1: current in the tare mode 0: Not in tare mode.
Bit6:1: Weight is beyond the range or haven‟t startup to zero. 0: Weight is in normal and has
startup to zero.
Send communication protocol passively
1>PC Request the connection firstly
PC Send one byte command 0x05 firstly.
Scale response one byte command 0x06.
PC can confirm the scale has connected via these two commands firstly.
2>PC Request to receive the weighing result.
PC sends one byte command 0x11.
scale response weighing result,response data format and the format of sending actively is basically the
same, just miss Flag2.

Pinnacle scale DigitOpBox protocol
1)Communication package format:
1.Communication package format:
A:without data column‟s format(not including DATA and DT SUM)
SUM = Byte0 + Byte1 + Byte2 + … + Byte10 + Byte11
B:with data column‟s format(LEN > 0)
SUM = Byte0 + Byte1 + Byte2 + … + Byte10 + Byte11
DT SUM = CRC16 ( Byte13 ~ Byte[13+LEN-1] )
Note:
1.When LEN is 0, DATA column and DT SUM are empty, at this time, data Packet total
length is 13 bytes.

17
2.When LRN is not 0, DT SUM‟s CRC checksum is only related with DATA column, and
is not related to the prior 13 bytes, at this time, data package total length is (13+LEN+2)
byte.
3.High order is in front and the low order is in rear to multi-byte column.
2. Communication package format explanation:
3. .communication command:
Set communication baud rate
set measuring result sending frequency
start or stop preset tare device
The response of OP box(Command failure)
The response of OP box(Command success )
2)Command explanation:
4. Set communication baud rate:( Successful response 0x800E,Failure response 0x800D)
Default the baud rate is 9600bps when power on. When the command is received successfully, change
baud rate by parameter PARA1.
XX = 0x01 : 115200 bps
XX = 0x02 : 57600 bps
XX = 0x03 : 38400 bps
XX = 0x06 : 19200 bps
XX = 0x0C : 9600 bps
Command use method:PC use the default baud rate 9600bps to send this command to OP box firstly, and
then continue to use 9600bps baud rate to response after OP box received the command. Then switch the

baud rate to the corresponding baud rate again after response data sending finished.
5. set measuring result sending frequency:( Successful response 0x800E,Failure response 0x800D)
Default frequency is sending 10 times measuring result in each second actively. When the
command is received successfully, change the frequency according to parameter PARA1.
XX = 0x0A : 10Hz
XX = 0x09 : 9Hz
XX = 0x08 : 8Hz
………
XX = 0x01 : 1Hz
XX = 0x00 : send measuring result passively, at this time you can achieve the measuring
result via the command “read measuring result”.
6.Read measurement results:
When initiative sending frequency is set as 0, achieve the measurement results: via this
command.
Please refer to note 1 about the returned data analysis.
7.Zero command:( successful response 0x800E,failure response 0x800D)
Sensor starts zero device after sending this command.
8.Tare command:( successful response 0x800E,failure response 0x800D)
Sensor starts tare device after sending this command.
9.Start or stop preset tare device:( successful response 0x800E,failure response 0x800D)
Sensor starts or stop preset tare device after sending this command.
The range of tare is 0~ the maximum tare value allowed.
When tare is 0, it will stop preset tare device. When tare is not 0, it will start preset tare
device.
10. Change measuring unit:( successful response 0x800E,failure response 0x800D)
The default unit is kg when power on, when command is received successfully, change
the unit according to the parameter PARA1.
XX = 0:standard unit(kg)

19
XX = 1: standard unit(g)
XX=6:British unit(pound)
XX=7:British unit(ounce)
Note 1:
The sensor returned the measured results of data format:
1.Data
When adopting 0x8002 command achieve measurement results, answering CMD is
0x8002.
When sensor is set for the certain frequency and sent measurement results automatically,
CMD is 0x8300.
PARA:the current temperature AD.
2.Data in data area
Flag: Bit0: 0 means weight is unstable 1 means weight is stable
Bit1: 0 means weight is in its range. 1 means weight is beyond the range.
Bit2: 0 means have startup to zero. 1 mean haven‟t startup to zero.
Bit3: 0means the current weight is more than the minimum weighing range
1 means the current weight is less than the minimum weighing range
Bit4: 1 the current OP box is soft unlock 0 the current OP box is not soft unlock
Bit5: 1 the current OP box hardware is unlock 0 the current OP box hardware is not
unlock
Bit6: 1 the lowest order of the result is always zero. 0 the lowest order of the result maybe
not zero.
Bit7: retain
Mode: 0:It stands for net weight weighing mode, at this time, tare and gross weight
column not transmission.
1:It stands for tare weighing mode.
2:It stands for Pre-set tare weighing mode.
Unit:
0: "Gram",
1: "kg",
2: "Tonne",
13: "Ounce",
14: "Pound",
15: "Kilo pound (kip)",
Decimal digits
Each weight value occupies 4 bytes, high-order in the front, and low in the rear. The highest Bit is the
sign bit. For example:

20
When receive the above data, it means: weight is stable, net weight weighing model, unit
kg, 3 decimal places, symbol is negative, -1.234 kg.
When receive the above data, it means: weight is unstable, net weight weighing model, unit
g, 0 decimal places, symbol is positive, 1234 g.
