Technical analysis of potential compatibility issues between the G-13 card terminal and connected coin hoppers. Focus on external factors and safe handling.
Detailed error descriptions will help to narrow down the source of the problem.
Cable length affects signal integrity.
Confirm the peripheral is officially supported.
Card terminals communicate with external peripherals (coin hoppers) via standardized interfaces (e.g., USB, RS-232). Baud rate mismatches, voltage irregularities (due to shared power), and electromagnetic interference (EMI) can disrupt communication. Electrostatic discharge (ESD) is a risk in dry environments and can corrupt data transmission. Signal attenuation due to cable length or damage can also cause errors. Corrupted firmware on either the terminal or the peripheral device can lead to compatibility issues.
Safe Handling: Before performing any troubleshooting steps, disconnect the G-13 from the power source to prevent electrical shock. Avoid touching any internal components. Do not use liquids directly on the device. Be aware of potential ESD hazards, especially in dry environments. Opening the G-13 card terminal will trigger internal anti-tamper mechanisms, rendering it permanently inoperable. Under no circumstances should the device be opened.
Regularly clean the terminal's exterior with a dry, anti-static cloth. Inspect interface cables for strain or damage and provide adequate strain relief. Ensure proper grounding of the terminal and peripheral devices to minimize ESD risk. Implement a schedule to periodically verify and update firmware versions.
Some card terminals and peripherals have a built-in diagnostic mode accessible via a specific key combination during startup. Consult the G-13's technical manual to determine if such a mode exists. This mode can often provide valuable diagnostic information regarding communication errors and device status. Use a USB isolator on the data line for testing. Ferrite chokes can be clipped onto the interface cable to reduce EMI.
