4. Setup and Installation
Follow these steps to install your DERAPID PCE-AC1200 WiFi Card:
- Step 1: Prepare Your PC
Power off your computer and unplug all cables. Open the side cover of your PC chassis. Locate and remove the chassis back panel corresponding to an available PCI-E slot. - Step 2: Insert the WiFi Card
Carefully align the PCE-AC1200 card with an available PCI Express slot (X1, X4, X8, or X16) on your motherboard. Gently push the card down until it is securely seated in the slot. - Step 3: Secure the Card and Attach Antennas
Use the provided fixing screws to secure the card's baffle to the host box. Then, screw on the two high-gain antennas to the connectors on the card's back panel. - Step 4: Connect Bluetooth USB Cable
Connect the 9-pin end of the Bluetooth USB cable to a F_USB connector (9-pin USB port) on your motherboard. Connect the 4-pin end of the Bluetooth cable to the dedicated Bluetooth port on the PCE-AC1200 network card. This connection is essential for Bluetooth functionality.
