How to use

Attach the DB9 male connector of the loopback adapter to the device's 9‑pin serial port.

Observe transmitted and received signals or error counters in your test program to verify line functionality. Remove the adapter after testing is complete.

Recommendations

Use the adapter only on powered‑off or properly secured equipment when connecting or disconnecting to avoid accidental signalling. For accurate diagnostics, combine the physical loopback with appropriate software tools that monitor serial communication and error statistics.
