User Label Description Files
Effective use of a User Label Description File (ULDF) provides several viewing modes. ULDF files are Comma
Separated Values (CSV) containing 12 to 14 of the following tokens:
ULDF Tokens
Label
1
,EquipmentID
2
,Name
3
,Units
4
,Min
5
,Max
6
,SigBits
7
,PosSense
8
,Resolution
9
,MinTransit
10
,MaxTransit
11
,LabelTy
pe1
12
,Offset
13
,DetailsList
14
Note: You can use any neutral text editor to create/modify your ULDF file, as long as it does not add
extraneous characters or remove characters.
Token Deviations from ARINC 429
2. Equipment ID is decimal rather than hexadecimal.
5. (and 6.) Min and Max are consolidated on ARINC tables. These tokens often contain information not
readily parsed. However, inside the ULDF, the Min and Max tokens have dedicated columns, and
therefore dedicated tokens.
Token Extensions from ARINC 429
12. Label Type1 are Binary, BCD, and Discrete.
13. Zero based Offset in bits (from bit 0 at the beginning of the message).
14. DetailsList contains additional information for BCD and Enumerated Discrete's.
For an Enumerated type details look like Enum: On|Off, Enum: Disengaged|Engaged, or Enum:
Off|Low|Medium|Full.
For a BCD type it would look like BCD: 3|4 or BCD: 2|4|4|4.
Unused Tokens
10. (and 11.) Min/Max Transit times 111 and 222 are not used.
5. (and 6.) Min/Max values are parsed but not used at this time.
8. PosSense is not used by the interpretation algorithm at this time.
ARINC 429 Filter Right-Hand Dialog
The Filter dialog can be used to exclude or include certain labels (user-defined or otherwise) from your
ARINC 429 decode.
Filter Mode - Choose your Message Filter Mode as either Only Show Selected Labels or Show All Labels
Except Those Listed.
Only Decode Labels - This field is only shown if the Only Show Selected Labels Filter Mode is selected.
Click this field and use the Virtual Keyboard (or your attached, USB keyboard) to provide your labels
(separated by semicolons) for exclusion.
Remove Labels - This field is only shown if the Show All Labels Except Those Listed Filter Mode is
selected. Click this field and use the Virtual Keyboard (or your attached, USB keyboard) to provide your
labels (separated by semicolons) for exclusion.
