CBNAAT Hardware Problem: Modules Not Detected

One of the common problems encountered while using the CBNAAT machine is the non-detection of the module.

Usually, there is a loss of communication between modules and software, leading to non-detection.

Origins:

• Ethernet connection between Personal Computer (PC) and CBNAAT is bad
• Power supply issue (main power or Universal Power Supply (UPS) fluctuations)
• Bad connection points between gateway board and modules
• Too high room temperature 

Solutions:

• Restart the instrument first and then the computer.
• Unplug and re-plug the ethernet cable between the PC and the instrument, then restart as above.
• Secure the power supply and use an adapted UPS/ surge protector.
• Check the temperature inside the module (should be below 39°C).
