1. 1

   Verify the supply voltage to the coin changer module's power input terminals is stable and within the specified operating range.

2. 2

   Inspect all communication cables and connectors between the main elevator controller and the coin changer for physical damage, proper seating, and secure connections.

3. 3

   Check the communication bus wiring for correct polarity, continuity, and absence of shorts or opens using an appropriate diagnostic tool.

4. 4

   Verify the communication parameters (e.g., baud rate, parity, data bits, stop bits, device ID/address) configured in the elevator controller match those configured in the coin changer module.
