Data Interfaces — Data Output¶

Data Output¶

You can define the data output parameter so that output is activated either when a print command is received or automatically synchronized with the display or at defined intervals (e.g., application programs and autoprint settings).

Data Output by Print Command¶

The print command can be transmitted by pressing the print key or by a software command (Esc P).

Automatic Data Output¶

In autoprint mode, data is output to the data interface port without an extra print command.
You can have synchronized data output automatically at defined display update intervals, with or without the stability parameter.
The interval time depends on the balance operating status and balance type.

If automatic data output is activated in the Device Configuration, it starts immediately after the balance is turned on.
You can also configure whether the automatic data output can be stopped and started by pressing the print key.

Data Output Formats¶

You can output the values displayed in the line for measured values and weight units with or without an ID code.

Example (without ID code):

+    253 pcs   (16 characters)

Example (with ID code):

Qnt +    253 pcs   (22 characters)

Data Output Format with 16 Characters¶

Blank display segments are output as spaces
Values without a decimal point are printed without a decimal point
Character type depends on position

Normal Operation (16-character format)¶

Pos	Description
1	+ / - / space
2	Space
3–10	Weight value (decimal aligned, leading zeros as spaces)
11	Space
12–14	Unit characters
15	CR
16	LF

Legend¶

* = Space
A = Displayed characters
S = Unit characters
CR = Carriage return
LF = Line feed

Stability in Live Autoprint Captures¶

On the observed MSE output, the unit field is blank while the displayed value is not stable and appears once the value stabilizes:

N     +    0.031
N     +    0.006 g

The parser treats numeric SBI lines with a blank unit field as valid readings with stable=False and unit=UNKNOWN; unit-bearing numeric lines are stable unless they also carry the explicit unstable marker.

Package behavior: when forced SBI open detects already-enabled autoprint, the session records autoprint as active. Use identify=False and consume with poll() or stream(mode="autoprint"); SBI calls that expect command replies are refused because live captures did not produce distinguishable replies while autoprint was active. If autoprint is changed from the balance front panel after opening, surprise output moves the session into autoprint mode, and refresh_sbi_autoprint_state() can be used to re-sniff and clear the mode once the stream has been disabled.

Special Outputs (16-character format)¶

Examples: - High → Overload
- Low → Underload
- Cal. Ext. → External calibration

Additional fields: - W = Draft shield status (optional)
- I = Ionizer (optional)
- Y,Y,Y = Draft shield doors
- XXX = Decimal value from binary control data

Control Information (Binary)¶

Decimal	Bit	Meaning
1	Bit0	0 = No error / ionizer off, 1 = Draft shield error / ionizer on
2	Bit1	0 = Motors off, 1 = Draft shield in motion
8	Bit3	0 = Learning off, 1 = Learning on
16	Bit4	0 = At least one door open, 1 = All doors closed
32	Bit6	0 = Motorized operation, 1 = Manual operation

Door status examples: - R,M,L = COO → Right closed, middle & left open
- R,M,L = OCC → Right open, middle & left closed

Error Messages (16-character format)¶

Examples:

Err ###
APP. ERR
DIS. ERR
PRT. ERR

### = Error code
Refer to error message section for details

Example Output¶

+    123.56 g

Position Breakdown¶

Position	Meaning
1	Sign (+/-/space)
2	Space
3–10	Weight value
11	Space
12–14	Unit
15	CR
16	LF

Data Output Format with 22 Characters¶

This format adds a 6-character ID code prefix to the 16-character format.

Structure¶

Pos	Description
1–6	ID code
7	Sign
8–15	Weight value
16–18	Unit
19–22	CR / LF / padding

Legend¶

K = ID code character
A = Displayed characters
S = Unit symbol
* = Space
CR = Carriage return
LF = Line feed

Example (22-character)¶

N     +123.56 g

Identification of Non-Verified Digits¶

Non-verified digits are marked with square brackets in printer mode.

Setting: Communication mode → PRINTER
In SBI mode, unverified values are not automatically marked

Special Outputs (22-character format)¶

Examples: - Stat High
- Stat Low
- Stat Cal. Ext.
- Stat Cal.Int.

Observed during live autoprint: starting internal calibration with ESC Z does not silence the data port. The stream switches to repeated Stat Cal.Int. status records during the calibration window, then resumes weight records. The parser treats those calibration records as non-weight status lines.

Error Messages (22-character format)¶

Examples:

Stat ERR ###
Stat APP. ERR
Stat DIS. ERR
Stat PRT. ERR

### = Error code
