G-13 POS System Configuration Troubleshooting - Solar Faults | terminalfaults.org

Technical Background:

Communication between the G-13 and the POS system relies on established protocols (e.g., TCP/IP, Serial). Configuration issues can stem from incorrect parameter settings, such as baud rate mismatches (Serial), incorrect IP addresses/ports (TCP/IP), or protocol version incompatibilities. ESD (Electrostatic Discharge), especially prevalent in dry environments, can temporarily disrupt communication or corrupt configuration settings. Voltage fluctuations and cable signal attenuation can also contribute to data transmission failures.

Symptoms:

The G-13 card terminal fails to communicate or integrate properly with the designated Canadian point-of-sale (POS) system. This may manifest as transaction errors, failure to transmit data, or unrecognized device errors.

Possible Causes:

Incorrect communication protocol selected on the G-13.
Baud rate mismatch between the G-13 and the POS system (if using Serial communication).
Incorrect IP address, subnet mask, gateway, or DNS settings on the G-13 (if using TCP/IP).
Firewall or network security settings blocking communication between the G-13 and the POS system.
Outdated or incompatible POS system software.
Cable damage or loose connections causing signal degradation.

Solution:

1

Verify the communication protocol required by the POS system (e.g., TCP/IP, Serial).
2

Access the G-13's configuration menu (refer to the G-13 user manual for instructions; typically involves pressing a specific key combination during startup).
3

If using Serial communication, confirm the baud rate, parity, data bits, and stop bits match the POS system's requirements. Set these accordingly within the G-13 configuration.
4

If using TCP/IP, ensure the IP address, subnet mask, gateway, and DNS settings are correctly configured and compatible with the network. Verify that the POS system and G-13 are on the same subnet.
5

Temporarily disable any firewall or network security software that might be blocking communication. Re-enable them one by one to identify the conflicting rule. Consult with your IT department before making permanent changes to firewall settings.
6

Ensure the POS system software is up to date with the latest version provided by the vendor. Check the release notes for compatibility information regarding card terminal models.
7

Inspect the communication cables for any signs of damage (e.g., frayed wires, bent connectors). Ensure cables are securely connected to both the G-13 and the POS system. Try swapping cables to eliminate cable faults.

Safety Warning:

Safe Handling: Disconnect the G-13 from the power source before performing any cleaning or cable maintenance. Avoid working in wet or damp environments. Do not attempt to open or disassemble the G-13; this will trigger tamper-proof mechanisms and void any warranty. ESD Precautions: Ground yourself before touching the G-13 or any of its cables, especially during dry conditions. Touch a grounded metal object to discharge any static electricity.

Prevention:

Regularly clean the exterior of the G-13 with a dry, anti-static cloth. Avoid using excessive force when plugging or unplugging cables. Secure cables to prevent strain and accidental disconnection. Consider using cable ties or a cable management system to reduce stress on connectors. In dry environments, use a humidifier to reduce static electricity. Consult POS system vendor for software/firmware updates.

Expert Tip:

Some G-13 models have a 'test connection' function within their configuration menu. Use this function to verify connectivity with the POS system after making configuration changes. If using Serial, check the 'flow control' setting (RTS/CTS or XON/XOFF) on both the G-13 and the POS. Mismatched flow control can cause communication errors. If you are still experiencing issues, capture network traffic between the G-13 and POS using Wireshark to diagnose further.

Frequently Asked Questions

•What specific error messages are displayed on the G-13 terminal or the POS system?

Specific error codes provide clues about the nature of the communication failure.

•What type of communication protocol is being used (Serial, TCP/IP, etc.)?

The communication protocol dictates the configuration parameters that need to be verified.

•Has there been any recent changes to the network configuration or POS system software?

Recent changes are a common cause of configuration issues.
