Table 3: TRI/TRX data
column
position
Designation
Purpose and particularities
1
Header
bus header for OBD/UDS (hexadecimal) 0 = no protocol
or specific Can Bus Identifier for protocol
2
Can ID
Can Bus Identifier (hexadecimal)
when using OBD/UDS/TP2.0: Address for querying the device
3
Format
0 -> Big endian; 1-> little endian; 2 -> VEMS (serial);
4 -> IEEE-754 float (Lenght=4)
4
Start byte
First byte in Can Bus packet (0-7)
5
Length
Length in bytes - 1, 2 or 4
for AINs: Attenuation strength 0-249 (0 = no attenuation)
6
unsigned
if the value is negative, please do not tick the box
7
shift Bit
moves the bit within the value to the right by position X
8
CAN Mask
Masks the value before shift (0 -> no mask applied)
9
Decimal places
Number of decimal places
10
Sensor Name
Sensor name (maximum 15 characters, no special characters)
11
initCalc
Can Bus value gets multiplied by this number
Result= ((Can Bus value & MASK)>>SHIFT) *INITCALC+INITOFFSET
12
initOffset
after multiplication this value is added
13
Mapper type
OFF, MAP (linear analog sensors); NTC (3 constants and pull-up
resistor (Steinhart-Hart))
14
MapperInfo1
Varies by mapper type
15
MapperInfo2
Varies by mapper type
16
MapperInfo3
Varies by mapper type
17
MapperInfo4
Varies by mapper type
18
AIN active
Internal analog sensor only; enables input pin polling
19
Min
Lower warning value
20
Max
Upper warning value
21
RefSensor
reference sensor: only if the RefValue for this sensor is exceeded,
warning is active
22
RefValue
Reference value for enabling the alert
24
Pop
Popup active when exceeding or falling below the warning value
6.1 Name encoding of TRI/TRX files
Our TRI/TRX files always have the following name:
𝑋 − 𝐴𝐵𝐶 − 𝑋. 𝑇𝑅𝐼 or 𝑋 − 𝐴𝐵𝐶 − 𝑋. 𝑇𝑅𝑋
The first letter identifies the protocol used. More information on the protocols can be found in
Chapter 6.2
The letters two to four identify the engine code letter or ECU. The engine code DAZA becomes X-
DAZ-X or a Syvecs ECU becomes X-SYV-X here. For freely programmable ECUs, however, the names
can also be longer than three digits (e.g. MaxxECU -> X-Maxx-X). The maximum number of digits
including ending is 15 characters.
The fifth or fifth last letter in the name of the TRI/TRX file indicates the units or languages used to
name the sensors:
• -G stands for the language German and units metric
