TROUBLESHOOTING your TriSonica Mini Sensor
Common Set-up Errors
Symptom: The TSM Sensor doesn’t seem to be doing anything.
Action
: Place the TSM Sensor near your ear and listen for a
quiet fast ticking sound
.
•
If you hear no sound, confirm the device the TSM
Sensor is connected to has power.
•
If the device has power, check that the USB port is
providing power, and the TSM Sensor has been
assigned an appropriate COM Port.
•
If the connected system is powered, check the TSM Sensor’s VIN and Ground
connections. Refer to the CONNECTION Chapter for specific details. Note that VIN
line is the only line that can handle voltages exceeding 5 volts.
•
If you’ve checked this twice and you still hear no sound, please contact us at
Symptom: There is no serial data coming from the TSM Sensor.
Action:
Refer to the CONNECTION Chapter to check to see whether you’ve swapped the
Transmit and Receive data lines. If those are correct, check to see whether
you’ve connected RS-232 wire to a UART input (such as on a Raspberry-PI,
Arduino, BeagleBone or the like). Fix any mis-wired connections you have found.
Symptom: The TSM Sensor sends garbled data.
Action
: Check your power supply and your receiving unit to make sure there is a ground
connection between the power supply, the serial port receiving data, and the
TSM Sensor. If those are correct, check your baud rate and parity settings on
your receiver; the TSM Sensor default transmission settings are 115200,8,n,1.
