Brainboxes 2 Port RS232 PCI Serial Card

Unlock legacy serial connectivity on modern PCs with the Brainboxes 2 Port RS232 PCI Serial Card. This universal PCI expansion card is engineered to deliver reliable, high-performance RS232 communication through two dedicated serial ports. Whether you’re integrating industrial equipment, POS peripherals, medical devices, embedded controllers, or legacy instrumentation, this card provides a robust, plug‑and‑play solution that blends seamless hardware compatibility with dependable Windows software support. With data rates up to 921,600 baud, 128-byte deep transmit and receive FIFOs, and 1 Mbit/s line drivers, you get uncompromising performance even in demanding environments. The included Windows drivers cover 32-bit and 64-bit operating systems, ensuring quick setup and broad compatibility across a wide range of PC configurations.

• Dual RS232 ports for immediate expansion: Add two reliable RS232 serial interfaces to your desktop PC in a single PCI card, making it ideal for connecting two serial devices or creating a small, scalable serial network without external hubs or adapters.
• High-speed, reliable data transfer: Support for baud rates up to 921,600 ensures fast, responsive communication with serial devices, which is critical for real-time data collection, instrument control, and time-sensitive communications.
• 128-byte deep FIFOs for smooth data flow: Both transmit and receive FIFOs are 128 bytes deep to minimize data overruns and underflows, helping maintain consistent data integrity even during bursts or heavy I/O activity.
• Robust signaling with 1 Mbit/s line drivers: Strong, noise-tolerant RS-232 signaling extends cable reach and keeps data clean in electrically noisy environments, enhancing reliability in industrial settings or long cable runs.
• Comprehensive Windows driver support: Includes drivers for all Windows 32-bit and 64-bit operating systems, enabling quick installation, broad OS compatibility, and straightforward device management via standard Windows tools.

How to install Brainboxes 2 Port RS232 PCI Serial Card

• Power down your computer and unplug it from the power source to ensure a safe installation.
• Open the computer case and locate an available PCI slot that aligns with the Brainboxes card’s interface.
• Remove the corresponding screw from the case I/O plate if needed, then carefully insert the Brainboxes PCI card into the slot until firmly seated.
• Secure the card with a case screw to ensure solid mechanical mounting and reliable contact in the PCI slot.
• Close the case, reconnect power, and boot the computer. The system should recognize a new PCI device.
• Install drivers from the included media or download the latest Windows drivers from Brainboxes. Follow the on-screen prompts to complete the installation for your Windows version (32-bit or 64-bit).
• Once the drivers are installed, connect your RS232 devices to the two DB9 connectors on the card and power them as required.
• Configure the COM ports in Windows (Device Manager → Ports) if you need to assign specific COM numbers or adjust port settings (baud, data bits, parity, stop bits, and flow control) to match your devices.
• Test the connection with a terminal program or your application to verify data transmission, reception, and error-free operation.

Frequently asked questions

• What does this card provide? It provides two RS232 serial ports via a universal PCI interface, enabling reliable COM port connections to legacy devices from a desktop PC.
