X Read weight value in increased resolution
Command :
[ADR][X]
Response : [ADR][X][STATUS][SIGN][WEIGHT VALUE]
Example :
Command : 01X
Response : 01XS+00123.41 (weight is stable and 123.41) or
01XD+00123.41 (weight is dynamic and 123.41) or
01XE (Error)
Comments :
The response includes weight data with divided the increment to 10.
Z Zero
Command : [ADR][Z]
Response : [ADR][Z][A]
(Zeroed)
[ADR][Z][N] (Zeroing could not be operated)
[ADR][Z][X] (Zeroing is disabled)
Comments :
Zero command can not work in net weighing.
Weight must be in zeroing range for all operating modes.
Status must be stable in 2 seconds time out delay. If so, Ack is send.
If it can not be stable in time out delay, Nack is send.
Checksum Calculation:
CHK is transmitted as two ASCII characters calculated with the Checksum formulation.
Checksum = 0
– (SUM of all response data before CHK)
Example: Read stable current weight data.
BSI Examples: (CHK is enabled and instrument address is 01)
Command: 01P[CHK][CR][LF]
Checksum
= 0 − (0x30 + 0x31 + 0x50)
= 0 − 0XB1
= 0x4F
= Char ‘4’ and ‘F’
Response: 01PS+000123.4[CHK][CR][LF]
Checksum
= 0 − (0x30 + 0x31 + 0x50 + 0x53 + 0x2B + 0x30 + 0x30 + 0x30 + 0x31+ 0x32 + 0x33 + 0x2E +
0x34)
= 0 − 0x02B7
= 0x49
= Char ‘4’ and Char ‘9’
