V Read digital outputs
Command: [ADR][V]
Response: [ADR][V][A][OUTPUTS]
Example:
Command: 01V
Response: 01VA3 (Output 1 and output 2 are active)
01VN (could not read outputs)
Comments: .
Outputs OUT-3 OUT-2 OUT-1
Bitwise 0 1 1
ASCII 3
W Set/reset digital outputs
Command: [ADR][W][OUTPUTS]
Response: [ADR][W][A]
Example:
Command: 01W3
Response: 01WA3 (Output 1 and output 2 will be set active)
01WN (could not set/reset outputs)
Comments: .
Outputs OUT-3 OUT-2 OUT-1
Bitwise 0 1 1
ASCII 3
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 unstable and 123.41) or
01XE (Error)
Comments: The response includes the weight data with the increment divided by 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: The Zero command does not work in net weighing mode. The Weight or Count must be within
the zeroing range for all operating modes. The status must be stable within 2 seconds delay
time. If so, Ack will be sent. Otherwise Nack will be sent.
CHK will be transmitted as two ASCII characters calculated with the checksum formula:
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
CHK = 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:
CHK = Char „4‟ and Char „9‟
