Troubleshooting

No Data Reports Received at AMBCS

Before troubleshooting, read and understand MicroMet Observations (pg 6), Stat

Commands (pg 7), and Checking MicroMet Communications Performance (pg 13).

If no data reports are being received from a MicroMet site, a site visit may be required to

determine the source of the problem. Since the MicroMet will only transport data that it

receives from the CR10X, troubleshooting procedures can be broken down to two

questions:

! Is the MicroMet receiving data messages from the CR10X?

! Is the MicroMet communicating properly with AMBCS?

First, connect your PC to the MicroMet and observe its communication statistics. If the

number of SPs and SYNCs are low to nonexistent, the problem is likely in the antenna,

interference, coax, receiver, or site selections. Try a test transmission to verify the

antenna/coax. If the test elicits no warnings, the problem is most likely in the receiver

and the MicroMet should be replaced.

If the SYNCs are good but no transmissions have been attempted (TX=0), then most

likely the MicroMet is not receiving data messages from the CR10X. Set verbosity to 5

and observe the absence of new data advisories after an expected data message time

frame. (Proceed to no CR10X data messages, page 19)

If the transmit to acknowledgment ratio is high, do a test transmission to verify the

antenna/coax. Remember that zero (0) reports at AMBCS should translate to zero (0)

acks at the MicroMet. Problems in the antenna/coax/battery should elicit HIVSWR or

Low Power warnings!
