how to install Brainboxes 2-Port RS232 Low Profile PCI Serial Port Card with LPT Parallel Port

To install this card, power down your computer and disconnect it from all power sources. Remove the computer case to access the motherboard and available PCI slots. Handle components with care to avoid static discharge.

• Identify a vacant PCI slot that matches the card’s form factor. If you are installing in a small form factor system, verify that there is adequate clearance for the card’s height and backplate.
• Insert the Brainboxes PCI card firmly into the PCI slot, aligning the connector with the slot and seating the card evenly. Secure the bracket to the chassis with the appropriate screw to hold it in place.
• Reassemble the case and reconnect power. Power on the PC and allow the operating system to begin booting.
• Install the drivers. Use the driver package provided for Windows 32-bit and 64-bit systems, or download the latest drivers from Brainboxes if available. Follow the on-screen prompts to complete the installation, then restart the computer if prompted.
• Verify installation. Open Device Manager and look under Ports (COM & LPT) to confirm that two new COM ports (for the RS232 serial connections) and the LPT port are listed. You can rename or reassign COM port numbers if needed through the Windows Port Settings to avoid conflicts with existing devices.
• Test functionality. Use a terminal program or your application software to communicate with devices connected to the two RS232 ports and the LPT parallel port. Check for reliable data transmission and printer communication to ensure the card is operating correctly in your environment.
