Maintenance and Troubleshooting

This chapter takes you through maintenance and troubleshooting procedures for the cellular endpoint.
Six- Wheel Encoders
If the odometer reads 123456, the Endpoint Manager should show 1 2 3 4 5 5 0 0.
The sixth digit displayed is a five, if the last digit on the odometer is five through nine. The sixth digit is a zero, if the last digit on the odometer is zero through four. The cellular endpoint adds two zeros on the end to provide an eight-digit reading to the host software.
Four-Wheel Encoders
If the odometer reads 1234, the Endpoint Manager shows 1 2 3 4 0 0 0 0.
The cellular endpoint adds four zeros on the end to provide an eight-digit reading to the host software.

Troubleshooting
This section provides examples of possible reading values and what they indicate.
The following table includes various reading values and steps you can perform to troubleshoot issues. Many of the issues display the same reading value, so be sure to review the definitions of the reading value to determine the most appropriate troubleshooting steps.

Table 11 ­ Example Reading Values

Reading Value :::::::: ????????
MMMMMMMMM
UUUUUUUUU UUUUUUUUU UUUUUUUUU

Definition

Troubleshooting

Indicates a timeout / failure to retrieve a reading

This value usually indicates a bad connection, no connection, or a cut wire between the endpoint and the meter register. Check the connection between the register and cellular endpoint.

Indicates a non-numeric reading
Indicates the meter read history is not available Indicates a parity check Indicates the Checksum failed Indicates a format error

Indicates the data received from the meter register is valid but contains a non-numeric value. For example: When the register wheel is in transition from one number to the next.
This might be a temporary condition if an old register is present. If the condition persists, investigate the register.
This reading can happen on R900 and LoRaWAN (v4 and v5) endpoints for the first 12 hours, and whenever the endpoint resets. The condition clears after 12 hours. If the condition persists, investigate the endpoint and register.
This reading can indicate an endpoint-to-register communication error, which is usually temporary.
This reading can indicate an endpoint-to-register communication error which is usually temporary. If the error is consistent, verify the register configuration.
This reading can indicate an endpoint-to-register communication error. If certain delimiters are missing from the packet, this error can occur. The error can also indicate a possible programming / configuration register issue. If the condition does not clear, investigate the register.

Definition Indicates an unknown register
Indicates a mismatched register type
Indicates a mismatched register ID Indicates a message timeout

Troubleshooting
This reading can indicate an auto-detection failure with no error found, or an incompatible register. The condition can also occur If the system receives a packet back from the register that the endpoint does not recognize.
This reading can indicate a register type has changed or the register was replaced (mismatched register protocol), or the register is replaced (moved from E-CODER to MACH 10 or ProCoder). If the condition occurs without replacing or swapping the register type, the endpoint receives a response from the register that does not match the expected response.
This reading indicates a register ID was changed or replaced. This c occur with an E-CODER replacement. If the error persists, investigate the register.
This reading indicates the endpoint timed out and the register stopped responding to the endpoint interrogations. This condition is temporary.

Error Messaging
If a user attempts to search for a cellular endpoint, but cannot return details, there are two possible error scenarios: 1. If your mobile device does not have service at the time you search, you see the message:
“No network connection. Try again later.” 2. If you search for an endpoint and nothing is returned, you see the message: “Cannot
find Endpoint. Please try swiping again or moving to a new location to try connection again.”
Meter Reading
You can use the Endpoint Manager to verify a valid installation of a cellular endpoint with a connected register. By accessing the Endpoint Manager section of the Field Manager app and searching an endpoint, you have access to the last meter reading and last call in time.
