Home > Support > FAQ > Pump Communications Fault Finding
If your pump communications (comms) are not working, or are working badly, there are some basic things to check before contacting ITL support.
These all indicate low-level communication problems. Some pump types are more prone to these kinds of problems than others, depending on how well their communications is designed and how well the protocol deals with errors.

You may see the "not responding" red X pump icon. This means there is no communication at all with the pump. |

If the "not responding" red X is flashing on and off then there is some communication, but not sufficient for the Enabler to successfully operate the pump. |

Another sign of problems is that the pump does not start delivering when authorised. |
Not all pumps in the field have the ability to communicate. They usually require configuration before they will connect, and sometimes require additional hardware (e.g. plug in boards), firmware updates, or jumper settings changed. Some older or simpler pumps may not have any ability to communicate, or may only be able to output a pulse signal.
The easiest way to know that the pumps will communicate, is: were the pumps previously connected to a console/POS/controller? If not, then you cannot automatically assume they are capable of communication. Ask the pump technician to confirm the pump's capability. Read our pump pages in detail to get tips on how to identify or confirm the pump setup.
The following flowchart provides extra help in identifying the cause of the problem. Please ensure you have run through this process before contacting ITL for support.
