OTHER HIGHLIGHTS:
  • Ease of use without any control components
  • Exchange of ATA Flash cards at any time. Task can be performed by test driver or other personnel, without the need to have a technician present
  • Start-up time is less than 2 seconds because there is no operating system to boot
  • Turn off delay up to 60 sec. - record events after ignition is turned off
  • Resolution of 50 sec. - every event and error frame is recorded
  • Secure data acquisition - power interruption is recorded by real-time clock - seamless continuation of recording after power is restored
  • No operating system - no system crashes, no corrupted data files
  • Long term recordings over weeks or months possible - filter and trigger functions reduce data recordings to certain events


DESCRIPTION:
UniCAN Professional is a flexible diagnosis and measurement device for 2 separate CAN-bus. The use of removable ATA Flash cards makes the UniCAN the perfect tool for data exchange with laptops.
UniCAN Professional features 2 operating modes which can be easily selected and configured with our Windows based UniCAN Manager program:

- Recorder Mode for selective data acquisition on the CAN-bus. Specific error conditions (Error Frames) can be triggered.
- Logger Mode for data acquisition in fixed time intervals. For data selection measurement channels and acquisition conditions can be configured.

CAN-Bus Support
UniCAN Professional supports CAN 2.0B (active). These are messages in Basic CAN (11-Bit Identifier) or Extended CAN (29-Bit Identifier) format.

The device is equipped with 2 CAN-bus controllers. We offer drivers for High-Speed CAN-Bus (ISO 11898) and Low-Speed CAN-Bus (ISO 11519).

Secure Data Storage:
UniCAN Professional is protected by a robust metal housing. A front cover secures the ATA card from being ejected which could otherwise be caused by vibrations.

ATA Flash PC Cards from SanDisk are supported because of their proven reliability. These cards do not contain any mechanical consumables which makes them perfect for rough environments. For long term data logging capacities up to 2 GB are available.

UniCAN Professional is protected against interferences. All measurement related data is saved and managed by UniCAN Professional utilizing a structure which is optimized towards security. In case of a disturbance, e.g. power failure or removal of the PC Card the measurement re-starts automatically. All previous data will be secured and available at the end of the logging.

Recorder Mode:
For diagnosis and long-term examinations of CAN systems the Recorder Mode can be used. This mode is very useful to log sporadic errors which in turn can be analyzed later on. Memory capacity is only limited by the ATA Flash card. UniCAN Professional records the following data:
  • Messages (Identifier and data)
  • Error conditions (Error frames with error condition)
In general, the entire communication over the bus can be recorded. As an option, a filter function is available to select specific identifiers. This will reduce data volume.

Recording of the bus communication is synchronized with a timer. It consists of data and time (resolution: 50 s).


Conditions of Recording for Recorder Mode:


For CAN diagnosis flexible conditions of recording are available. The following parameters can be utilized in the Recorder Mode:

  • CAN Identifier
  • Data content (physical value, definition by CANini)
  • Error Frame
  • Digital Input (external)

It is possible to select between triggering and gate function. If a triggering function is reached the initiated start of the recording remains active for indefinite time.

If the Gate function is selected recording is active as long as the condition of recording is valid. For short-term or single occurrences (Identifier or Error Frame) a hold time (100 ms to 60 sec) can be specified to record subsequent information. In addition, it is possible to record a pre-event history (app. 80 KByte data). Up to 8 conditions of recording can be combined logically in order to select specific events.

For start of the ignition a start delay (100 ms to 60 sec) can be specified, at which the condition of recording is not applicable. This is very helpful to eliminate irregular conditions at the CAN-bus.
Special Applications for Recorder Mode:
For special applications the Recorder Mode allows for specific settings for adaptation to the physical CAN-bus:
  • Instant of Sampling
  • Access to Bit Timing Register (BTR)

The following functions can also be used for one CAN channel:
  • Recording of Remote Frames
  • Triggering of Remote Frames
  • Listen-Only Operation (no acknowledge)

Log Mode:

For recording of measurement values the Log Mode is used. This operating mode allows to select up to 96 different measurement variables at the CAN-Bus to be written onto ATA Flash Card at a time.

Definition of the measurement variable is performed easily and flexible by selection of the data elements in CANini or CANdb, e.g. "rpm", "oil temperature".

Measurement variables are supplemented with the following parameters in UniCAN Manager in order to fully describe the measurement:
  • Data source (CAN-Bus 1 or 2)
  • Time interval of the recording (1ms, 2ms, 5ms, 10ms,..., 10s, 30s, 60s)

For every measurement variable a separate time interval can be selected. All measurement data are stored in the input buffer of UniCAN Professional until they are overwritten by new data from the CAN-bus or until the data are written to a memory card according to the specified time interval.

Conditions of Recording for Log Mode:

Flexible conditions of recording are available. The following values can be used:
  • Data content (physical value, definition by CANini)
  • Digital input (external)


It is possible to select between triggering and gate function (as in Recorder Mode). Up to 8 conditions of recording can be combined logical.

Log-File:

For Recorder and Logger Mode the following status information with time stamp are stored into a separate log file:
  • Power Supply (on/ off)
  • Ignition (on/ off)
  • Recording (active/ interrupted)

UniCAN Manager:

For configuration of a recording the Windows program UniCAN Manager is available. It features access to communication data which have been previously defined in CANini (or CANdb). You can utilize common names (like "rpm") to define parameters for recording (triggering threshold, etc.).

In addition, common parameter for recording are defined UniCAN Manager:
  • Name of recording (for subsequent identification)
  • User comment (max. 60 KByte)
  • CAN-Bus transfer rate (up to 1MBit/s)
  • Basic (11 bit) or Extended (29 bit) identifier
  • Slowing down time for turning off ignition (100ms to 60 sec)
  • Memory organization (configuration as one time or looping memory)

UniCAN Manager is also used for data transfer to a computer in conjunction with the recording. Output of the recorded data is in ASCII format, which can be imported into MS EXCEL and other programs for further analysis.

UniCAN Manager is very handy to divide large segments into smaller packages. The number of single files are determined by selecting file length and time frame (day, hour, minute).

RS232 Interface (Serial Port):

UniCAN Professional is connected to a computer running Windows operating system via a serial RS232 interface. The following functions are available:
  • Set real-time clock (Service Mode)
  • Online display (ASCII Format)

The Online Display is available during measurement for control purposes. A laptop can be used to display the following information in an ASCII window (Windows Hyper-Terminal):
  • Time
  • UniCAN System Utilization
  • CAN Bus Utilization (Recorder Mode)
  • Measurement data (Logger Mode)

The time interval for output of the measurement data is selectable between 1 s and 10 s.
