How to use

Install the low profile bracket into a free low profile slot on the PC chassis. Connect the cable to the internal COM header or internal serial connector on the motherboard or adapter, and secure the DB9 connector to the external device. Ensure connectors are properly seated and fasten screws if present to prevent accidental disconnection.

Recommendations

Use the cable for short-distance serial connections inside and just outside the PC chassis. Avoid routing the cable near high-voltage or high-frequency sources to reduce interference. Verify COM port settings (baud rate, parity, stop bits) in the operating system or device firmware to match the external device.
