How to use

Connect the USB Type-C plug to a host device with a compatible USB Type-C port. Attach the DB9 connector to the serial device's RS-232 port and secure the connector if the device provides screws. Observe the nine LEDs in the DB9 connector to verify which RS-232 control and data lines are active and to confirm USB voltage presence. Use the adapter for data transfer or device control as required by the connected equipment; no additional power source is normally needed when the host provides USB power.

Recommendations

Use this adapter for temporary connections and diagnostics; for permanent industrial installations, verify mechanical strain relief and connector fastening. Ensure the host device supports USB to serial adapter drivers if required by the operating system.
