CPI MEI Talos Bill Validator: Moneris Terminal... | terminalfaults.org

Technical Background:

Communication between the MEI Talos and the Moneris terminal typically utilizes a serial protocol (RS-232 or similar) operating at a specific baud rate and voltage level (e.g., 5V or 12V). Signal attenuation due to cable length or damage, electrical noise (ESD), or incorrect baud rate settings can disrupt communication. The 24V DC power supply to the bill validator must be stable; voltage fluctuations can affect the internal logic and communication circuitry.

Symptoms:

The CPI MEI Talos bill validator accepts bills but fails to transmit transaction data to the Moneris terminal. The Moneris terminal displays a communication error or does not register the bill acceptance.

Possible Causes:

Cable Damage: Physical damage to the communication cable (cuts, crimps, loose connectors) interrupting signal transmission.
Baud Rate Mismatch: The baud rate setting on the MEI Talos does not match the baud rate configured on the Moneris terminal.
Power Supply Instability: Fluctuations or insufficient voltage from the 24V DC power supply affecting the validator's communication module.
Connector Corrosion: Corrosion on the communication cable connectors creating high resistance and signal degradation.
Software Glitch: Firmware issue within the MEI Talos or Moneris terminal causing communication errors.
Grounding Issue: Inadequate grounding leading to electrical noise and interference on the communication lines.

Solution:

1

Power Cycle: Disconnect and reconnect power to both the MEI Talos and the Moneris terminal. Wait 60 seconds before repowering.
2

Cable inspection: Visually inspect the communication cable for any signs of damage, cuts, or crimps. Ensure connectors are securely attached.
3

Connector Cleaning: Use a contact cleaner (e.g., DeoxIT) to clean the communication cable connectors and the corresponding ports on the MEI Talos and Moneris terminal.
4

Baud Rate Verification: Verify that the baud rate settings on both the MEI Talos and the Moneris terminal are identical. Consult the respective manuals for setting procedures.
5

Voltage Measurement: Using a multimeter, measure the 24V DC power supply voltage at the MEI Talos. Ensure it is within the specified tolerance (e.g., 24V ± 10%).
6

Grounding Check: Verify that the MEI Talos and Moneris terminal are properly grounded. Check ground connections for corrosion or looseness.
7

Firmware Update: Check the CPI and Moneris websites for any available firmware updates for the MEI Talos and Moneris terminal, respectively. Follow the manufacturer's instructions for updating.

Safety Warning:

High voltage is present within the MEI Talos. Prior to any inspection or maintenance, ensure power is disconnected using Lockout/Tagout (LOTO) procedures. Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses. Ensure adequate ventilation when using contact cleaners.

Prevention:

Regularly inspect communication cables for damage and ensure connectors are securely fastened. Clean connectors periodically to prevent corrosion. Implement proper cable management to prevent strain on the communication cable. Consider using a surge protector to protect the MEI Talos and Moneris terminal from power surges. Protect the kiosk from extreme weather (consider a heated enclosure if ambient falls below -10C).

Expert Tip:

If the communication issue persists, try using a different communication cable. A known-good cable can quickly determine if the existing cable is faulty. Alternatively, if possible, connect a laptop to the MEI Talos using the same communication protocol and monitor the data stream to diagnose the issue further.
