6.2 Protocols
CANchecked data displays support a variety of CAN protocols. For the different protocols, there are
different firmware for your data display:
• standalone engine control units (ECUs) use the standard firmware (S-ABC-X. TRI)
• Direct access to the vehicle Can Bus (S-ABC-X. TRX)
• Data retrieval with OBD2 protocol uses the OBD2 firmware (O-ABC-X.TRX)
• the TP2 protocol is used with the TP2 firmware (T-ABC-X.TRX)
• Vehicles that allow UDS protocol use the UDS firmware (U-ABC-X. TRX)
• BMW E/F series for vehicles of the E and F series (B-ABC-X. TRX)
Depending on the installed firmware, you will only see TRI/TRX files for the corresponding firmware
in the TRI/TRX selection list of the display. All files for other firmware will be hidden. For example, if
OBD firmware is installed, you will not see TRI/TRX files for standalone ECUs, but only files with "O-".
More information on changing and updating the firmware can be found in Chapter8.
6.3 TRI/TRX file problem
If your data display starts and no TRI/TRX file is selected or present on the display, you will receive an
error message in a large yellow box.
Figure 14: TRI/TRX error message
To select a TRI/TRX file , navigate to the list of files available on the SD card via Setup -> Can Bus ->
TRI/TRX File.
