Troubleshooting

To correct the error, make sure that the SDI-12 device is properly
connected. The SD900 will detect the sonde during the next scan
interval.

After the sonde is detected, choose SDI-12 from the
DIAGNOSTICS screen.

The display shows the number of signals sent by the SD900 (TX)
and the number of signals received (RX) from the SDI-12 device.

If the RX number is 0, the SDI-12 device is not communicating with
the SD900.

If the TX number matches the RX number, the transmissions have
been successful.

If the TX and RX numbers do not match, examine the event log to
see the number of failed transmissions and the reasons for the
failures.
