Optional Optical Bearing Sensor (OBD)
If the system is configured to include an Optical Bearing Device there will
be an additional ‘
Get OBD Input ’ button in the LOP window. Selecting this
button will open a dialogue box indicating to the user that the system is
ready to receive data from the OBD.
To use optional OBD
1. Click the Get OBD Input button. An
Action Required dialogue window
appears informing the operator that the
system is waiting for message data from
the OBD.
Once the input from the OBD has been
received the dialogue will close and the
Bearing value in the LOP menu will be
populated with the received data.
2. If data is not received from the OBD after
a timeout period of 60 seconds, or if the
user clicks the
Cancel button, the system will revert back to the
menu and allow manual entry of data.
If the bearing value is entered using an OBD, the time the message was
received from the OBD will be used and shown in the
Time field. The value
represents the time the LOP was taken and used for dead-reckoning
calculations.
