Hantle 1700W POS Compatibility Diagnostic - Solar Faults | terminalfaults.org

Technical Background:

The Hantle 1700W typically communicates via a serial interface (RS-232 or USB emulating serial). Baud rate mismatches, incorrect data parity settings, or signal attenuation due to cable length or damage can prevent successful communication. ESD events, especially prevalent in dry winter conditions, can corrupt data transmitted between the validator and POS. 24V DC logic voltage fluctuations may affect solenoid operation. The POS system's communication protocol must be correctly configured to match the Hantle 1700W's expected format.

Symptoms:

Reported inability of the Hantle 1700W bill validator to communicate correctly with the Point of Sale (POS) system. This manifests as either no response from the validator, intermittent errors, or incorrect transaction data being recorded. Observed behaviour might include validator failing to accept bills or continuous error messages being displayed on the POS terminal.

Possible Causes:

Incorrect baud rate setting on either the Hantle 1700W or the POS system.
Faulty or damaged serial cable connecting the validator and POS system.
Loose or corroded connector pins on the serial cable or communication ports.
Software incompatibility between the Hantle 1700W firmware and the POS system software.
Excessive cable length causing signal degradation, especially in electrically noisy environments.
Electrostatic discharge (ESD) damaging the communication interface of the validator or POS.

Solution:

1

Verify the baud rate setting on both the Hantle 1700W and the POS system. Ensure they match (typically 9600 or 19200 bps). Consult the Hantle 1700W manual and POS system documentation for configuration instructions.
2

Inspect the serial cable for any signs of physical damage, such as cuts, crimps, or bent pins. Replace the cable with a known good cable of appropriate length (under 1.5m recommended) and shielded.
3

Carefully disconnect and reconnect the serial cable at both the Hantle 1700W and the POS system. Check for loose or corroded pins. Use a contact cleaner (isopropyl alcohol) on the connector pins if necessary, ensuring it is completely dry before reconnection.
4

Check the POS system's software configuration to ensure it is properly configured to communicate with the Hantle 1700W. Verify the correct communication protocol and data format are selected.
5

Temporarily relocate the Hantle 1700W and POS system to a different electrical outlet to rule out power-related issues affecting communication. Use a dedicated circuit if possible.
6

If applicable, update the Hantle 1700W firmware to the latest version available from the manufacturer. Ensure the POS software is also up to date.
7

Review the Hantle 1700W error logs (if available) for specific error codes that may indicate the nature of the compatibility issue.

Safety Warning:

Exercise Safe Handling. Disconnect the Hantle 1700W from the power source before inspecting or replacing cables. Be aware of potential ESD hazards, especially during dry conditions. Do not open the validator casing, as this will void the warranty and may damage the device. High voltage circuits are present internally. Do not attempt internal repairs.

Prevention:

Regularly inspect the serial cable for damage. Keep the cable length as short as possible. Ensure proper grounding of the Hantle 1700W and POS system. Control ESD by using anti-static mats and wrist straps, especially during dry weather. Clean the touchscreen with a recommended LCD cleaner to maintain accurate input.

Expert Tip:

Try using a USB to Serial adapter with a built-in ferrite choke to reduce electrical noise on the serial line. A common issue is ground loops between the POS and the validator. If the POS uses a USB connection, ensure it is plugged directly into the motherboard USB and not a front panel connector. Some POS systems have a 'cash drawer' serial setting that needs to be enabled for bill validators to work.

Frequently Asked Questions

•What baud rate is the POS system configured for?

Verify the baud rate setting in the POS system's device configuration menu. Common baud rates are 9600 and 19200 bps.

•Is the serial cable shielded and of appropriate length?

A shielded cable helps reduce interference. The cable length should be as short as possible, ideally under 1.5 meters.

•Are there any error messages displayed on the POS system or the Hantle 1700W?

Note down any specific error codes, as these can provide clues about the nature of the problem. Consult the Hantle 1700W manual for error code definitions.
