Serial Cable DeLOCK 90494 USB Type-C RS-232 DB9 Black 0.35m

The DeLOCK 90494 is a 0.35 m serial cable that converts a USB Type-C connection to two RS-232 DB9 ports. Designed for stable data transfer, the compact black cable weighs 62 g and provides compatibility with devices requiring a serial interface, such as printers, measuring instruments, controllers and IoT devices. Each RS-232 port includes status LEDs for transmit, receive and USB power to help monitor connection activity.

Advantages

The adapter offers two RS-232 DB9 interfaces from a single USB Type-C plug, enabling connection of legacy serial devices to modern hosts. Its short 0.35 m length reduces signal loss and clutter while keeping the setup compact. Integrated LEDs on each port provide clear indication of transmission, reception and USB power status for quick diagnostics.

How to use

Connect the USB Type-C plug to a compatible host port. Attach RS-232 DB9 cables from the devices to the adapter’s DB9 ports and secure any screws if present. Power and communication status are shown by the three LEDs on each RS-232 port (transmit, receive and USB power). Install any required drivers on the host system if prompted, then configure the serial port settings (baud rate, parity, data bits, stop bits) in the device or application to match the connected equipment.

Recommendations

For reliable operation, use the DeLOCK 90494 in environments within normal temperature and humidity ranges, avoid excessive bending near the connectors, and confirm correct serial settings on both host and device. If communication issues occur, check LED status indicators and verify driver installation and cable connections.
