Timing devices

Setting up an event in BBT timing software includes setting up and assigning timing devices to timing points. Accurate setup of timing devices is essential in getting accurate results.

Adding and maintaining a timing device

To add a timing device to an event start in the 'Timing' mode in the menu to the far left after which you go to the 'Timing devices (Setup)' to the far right. A new timing device can now be added by choosing:

  1. 'Setup'
  2. 'Add device'
  3. 'Type'
  4. Choose what timing unit you will be using from the drop down menu
  5. Type in the IP-address of the timing unit
  6. 'Add'

It is now possible to assign the timing unit to a location:

  1. Click on the hand
  2. Choose from the drop down menu the location where you will using the timing unit. Note: If you have not yet defined the timing locations just choose 'None (unassigned)'. You can always assign a timing unit to a location later in the setup process.
  3. Press 'Done' when having added the timing units you will be using for the timing of the event

Note: The BBT timing software works with all common open timing units and the list of supported units is constantly being updated. Please contact us if you can not find your timing unit on the list. Most likely it can be added.

Assigning a timing unit

It is now time to link the chosen timing units to the timing points:

By sure to press 'Setup' to be in setup mode

  1. Click on the pen symbol in the upper left corner of the graphical representation of the timing point you want to assign a timing unit.
  2. Go to 'Timing unit location' and choose the location of the timing unit from the drow down menu.
  3. 'Save'.

Note: The last digits from the IP address of the timing unit will now be visible in the graphical representation of the timing point which has just been assigned the timing unit.

Connecting a timing unit

The last step in the process is to connect the timing units which is done by pressing 'Timing units' or 'Start all' in the 'Overall status' window to the left to complete the setup

Connection has been established if the color turns green

Note: If one or more boxes are not connected the color will turn red. To the very right in the 'Timing units (Setup)' window you will be able to see which boxes are not connected.

Replaying / rewinding

It is always possible to replay data from a timing unit if connection to the unit has been lost for a period of time:

  1. Press 'Replay' at the bottom of the 'Timing units' window when in the 'Timing' mode.
  2. Choose the timing unit and the time slot you want to reply.
  3. The replay of raw data is started when pressing 'Next'.

Advanced: Splitting a unit

It is possible to use the same timing unit for multiple timing points simultaneously. A common split setup is using an 8-port timing unit where the antennas 1-4 are used for the start point and 5-8 for the finish point. Splitting a timing unit in the BBT timing software is done by:

  1. Go to the 'Timing units (Setup)' window and choose 'Add unit'.
  2. Click on 'Select specific antennas/active loops only'
  3. Add the number of antennas you want to position in a timing point (such as antennas 1-4 for the start point).
  4. Add the timing unit with the chosen number of antennas to the event by pressing 'Add to event'.
  5. Press 'Done' to exit the menu

Now add the timing unit to the timing point: Go to the 'Timing units (Setup)' window and press the finger icon to the right of the timing unit and assign the timing unit to the timing point (in this case assign the unit including antennas 1-4 to the start point).

The whole process can now be repeated until all antennas have been assigned to a various timing point. Thus, to assign the antennas 5-8 to the finish point choose the same timing unit but now specify the use of antennas 5-8, add the unit to the event and assign the unit including antennas 5-8 to the finish point. Now the same timing unit will be assigned to two different timing points (start and finish) with 4 anteannas (1-4) for the start point and 4 antennas (5-8) for the finish point.

Note: Splitting a timing unit is possible but reducing the number of antennas in a timing point increases the risk of not reading all chips/tags passing that point.
