7 TROUBLESHOOTING

7.1 The Echotrac E20 does not seem to be working

If the Echotrac E20 does not seem to be working correctly, perform these steps to find the cause.

(a) Check if the power LED is on.

(b) The Echotrac E20 has a Standby bit that is turned on by default. Try to communicate with
the Echotrac E20 via the SBES UI.

(c) Check that all the cables are properly connected and intact. If cables are not properly
secured, electrical signals may not be transmitted or received.

(d) A blinking TX LED means that the digitizer is firing, but the data may not be sent out on
the COM port of the Echotrac E20. The Echotrac E20 could be in Standby mode.

(e) Make sure the Echotrac E20 is not in Standby mode.

(f) Make sure you are using the correct COM port. Windows will display an error message if the
port cannot be used or if it is already open/used by another program.

These programs or devices use COM ports: Modem, Mouse, Scanners, and Printers.

(g) Try toggling the COM port off and on with the Windows application software you are using.

(h) Try powering down the Echotrac E20 and powering it back up again. If the Echotrac E20 is turned
on before the computer, it may interfere with initializing and setting up communication channels.

7.4 Known problems with Transducer

Always make sure that the transducer face has been cleaned with mild soap to improve the interface
between the transducer and the water. Sometimes a thin layer of air can be trapped on the face of the
transducer. This will result in poor or no signal return from the transducer.
