PAX G10-S 'No Communication' Error Diagnostic - Solar Faults | terminalfaults.org

Technical Background:

Serial communication failure can stem from insufficient voltage levels, incorrect baud rate settings (though less likely in a locked system), or signal attenuation due to cable damage or excessive length. Electrostatic discharge (ESD) can also corrupt data transmission or damage the serial interface. Verify voltage levels from the power supply using a multimeter on the external power connector (observing correct polarity) if possible. Note the G10-S is a PCI-PTS device.

Symptoms:

The PAX G10-S displays a 'No Communication' error. The terminal is unable to transmit or receive transaction data. Observed failure occurs in a retail checkout environment.

Possible Causes:

Faulty serial cable: Internal wire damage or connector corrosion.
Loose cable connection: Insecure connection at either the terminal or host device.
Power supply issue: Insufficient voltage to the G10-S.
ESD damage: Electrostatic discharge affecting the serial communication chip.
Incorrect serial port configuration (if applicable, though unlikely in typical deployment).
Firmware corruption: Rarely, corrupted firmware can impact communication.

Solution:

1

Safe Handling: Disconnect the power adapter from the PAX G10-S.
2

Inspect the serial cable: Check for physical damage (cuts, kinks, fraying).
3

Secure cable connections: Ensure the serial cable is firmly plugged into both the G10-S and the host device.
4

Test with a known good cable: Replace the existing serial cable with a verified working cable.
5

Power cycle: Reconnect the power adapter to the G10-S and allow it to fully power on.
6

Check power supply voltage (if applicable): Use a multimeter to verify the correct voltage output from the power adapter.
7

Contact support: If the issue persists, contact PAX support for further assistance. Do NOT attempt to open the device.

Safety Warning:

Electrostatic discharge (ESD) can damage the terminal's electronic components. Avoid touching the serial connector pins directly. Ensure the terminal is placed on a stable, dry surface. Do NOT attempt to open the terminal casing due to PCI-PTS anti-tamper mechanisms.

Prevention:

Implement cable strain relief to prevent damage to the serial cable and connectors. Regularly clean the terminal exterior with a dry, anti-static cloth, especially during dry winter months to minimize ESD buildup. Avoid placing the terminal near sources of electromagnetic interference.

Expert Tip:

If the G10-S connects via a USB-to-Serial adapter, try a different USB port or adapter. Some USB ports may provide insufficient power, leading to intermittent communication issues. A ferrite choke can be added to the serial cable to reduce EMI.

Frequently Asked Questions
