## Summary description

The EXSYS EX-46012 is an internal serial adapter featuring a PCIe host interface and ASIX MCS9901CV-CC chipset. It has male connectors and operates at a power supply input voltage of 3.3 V. Compact dimensions of 62 mm width and 77.5 mm depth make it suitable for various applications.

## Long description

The EXSYS EX-46012 PCIe internal serial adapter provides two RS-232 serial ports driven by high-performance 16C550-compatible UARTs. Designed for installation in PCs, small workstations or servers, the card uses a PCIe host interface and the ASIX MCS9901CV-CC chipset. The adapter is supplied with two low-profile brackets to fit compact computer cases and requires a 3.3 V power input; its compact dimensions (62 mm × 77.5 mm) suit space-constrained systems.
Advantages
The EX-46012 adds two reliable RS-232 ports via a PCIe slot, offering compatibility with legacy serial devices and systems that require UART-based communication. The onboard ASIX MCS9901CV-CC chipset and 16C550-style UARTs ensure consistent serial performance, while the included low-profile brackets allow flexible installation in standard and small-form-factor cases. The adapter's internal design and grey finish integrate easily into a range of hardware environments.
Suitable for
Connecting industrial or legacy serial devices (modems, barcode scanners, PLCs)
Expanding serial ports on desktops, servers, or small workstations
Embedded systems or applications requiring reliable UART-based communication

How to use
Install the EX-46012 into an available PCIe slot on the host system, secure the card using the appropriate bracket (standard or low-profile depending on the case), and connect any required internal power if applicable. After physical installation, power on the system and install or verify the correct drivers for the ASIX MCS9901CV-CC chipset so the operating system recognises the two RS-232 serial ports. Configure serial port parameters (baud rate, parity, data bits, stop bits) in your application or OS serial communication settings as needed.
Usage recommendations
Use the supplied low-profile brackets for small-form-factor cases and ensure the host system provides a stable 3.3 V supply. For reliable operation with industrial equipment, use quality shielded serial cables and verify grounding. Confirm driver compatibility with your operating system before deployment.
