Recommendations

For stable communication, use a direct connection without excessive cable coiling and avoid high-interference environments. Confirm baud rate, parity, and other serial parameters on both the host and the connected device. When using with legacy equipment, ensure the RS-232 wiring and grounding match the device requirements.
