USB Type-C to Serial DB9 Adapter DeLOCK 90414

The DeLOCK USB Type-C to Serial DB9 Adapter 90414 is a compact cable that connects devices with an RS-232 DB9 interface to a USB Type-C port. The adapter includes an integrated RS-232 tester with nine LEDs located in the DB9 connector to show the status of the serial data lines and the USB power supply. With a 2 m cable and a lightweight black design, it suits situations where a reliable physical serial connection is required from modern USB Type-C hosts.

Advantages

The adapter combines a USB Type-C to RS-232 DB9 converter and an LED-based RS-232 tester in one unit, allowing connection and basic diagnostics without additional tools. The nine LEDs provide real-time visual feedback on individual serial control and data lines as well as USB voltage presence. The 2 m cable length offers flexibility in device placement while the 26 g weight keeps the assembly portable.

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.
