If there is a chance that the baud rate has been changed and the Search IMU button does not find
the IMU, systematically check each baud rate option in the SMC IMU Configuration Software until
the correct rate is found.
When applying a setting change in the SMC configuration software the output signals can display bad
data. This occurs during the automatic restart of the sensor unit, the values will settle after a few
minutes.
No GPS or Gyro data is received
Select the relevant Verify button in the Serial Input configuration screen.
If no data is received check the baud rate setting of the GPS device. Set the GPS to 4800 baud rate if
set higher and verify again.
Check the wiring of the RS232 serial input.
Heading Information from GPS is not shown in the Output Protocol
There is a check button in the SMC configuration software to accept the heading string from the GPS
($GPHDT) Check the box labeled Use GPS Heading input for Yaw aiding if available.
