Code 118 USB Buffer Overflow.

This is a software problem. The module produces data faster than the computer on which the chromatography data system is running can process the data.

1. In the chromatography data system, disconnect and reconnect the module.

2. If this does not solve the problem, update the firmware or the chromatography data system version.

3. If the problem persists: Also, third-party software on the computer, for example, virus scanners or poor computer performance can cause the problem. Contact the onsite IT department.

Code 120 System interlink request timed out.

Communication with the module failed. The module did not respond in time.

For the module for which the message appears:

1. Turn on the module if it is not yet turned on.

2. Check the system interlink connections to the module. Verify that all system interlink cables are connected at both ends.

3. If the message persists, replace the system interlink cables.

Code 126 Device lost system interlink connection.

All other modules on the system interlink bus are turned off or a firmware download is performed on all other modules.

1. Check whether all other modules have been turned off or a firmware download is performed on all other modules on the bus.

2. Wait until one of the modules on the bus is turned on or the firmware download is complete.

3. A system interlink cable may be disconnected from the module or is defective. Check the system interlink connections to the module. Verify that all system interlink cables are connected at both ends.

4. If the message persists, replace the system interlink cables.

Code 128 System interlink data errors.

A system interlink cable may be disconnected from the module or defective.

  1. Check the system interlink connections to the module. Verify that all system interlink cables are connected at both ends.
