Product information

Description

The EXSYS EX-44082 is an internal RS-232 interface card designed for installation in PCIe slots. It provides a single RS-232 output interface for connecting serial devices and supports baud rates up to 921.6 Kbit/s. The card includes a 16-byte FIFO buffer, supports configurable data bits (5, 6, 7 or 8), and uses a 5V output voltage. With compact dimensions of 78.5 mm x 66.8 mm and a weight of 188 g, the EX-44082 is intended for systems that require a reliable onboard serial port implementation compatible with a range of Windows operating systems.

Advantages

The EXSYS EX-44082 delivers high-speed serial communication within a small form factor suitable for PCIe-equipped motherboards. Its support for baud rates up to 921.6 Kbit/s and selectable data bit lengths offers flexibility for various serial protocols. The built-in 16-byte FIFO buffer helps manage data bursts and reduces CPU load during transfers. Native compatibility with common Windows versions simplifies driver integration and deployment in existing systems.

Suitable for

Adding an RS-232 serial port to desktop PCs or workstations with available PCIe slots
Connecting legacy serial devices such as modems, barcode scanners, and industrial controllers
Embedded or industrial PCs that require compact, low-weight serial connectivity
Software development and testing environments that require configurable serial parameters

Key specifications

Host interface: PCIe
Output interface: RS-232
Maximum baud rate: 921.6 Kbit/s
FIFO buffer size: 16 bytes
Data bits: configurable to 5, 6, 7 or 8 bits
Output voltage: 5 V
Dimensions: 78.5 mm x 66.8 mm
Weight: 0.188 kg
Internal installation: yes
Compatible operating systems: Windows 10, 8, 7, 2000

How to use

Install the EXSYS EX-44082 in an available PCIe slot on a powered-off system following standard anti-static precautions. Secure the card to the chassis and connect the external RS-232 cable to the output interface. Power on the system and install the appropriate drivers for the target Windows operating system if required. Configure serial port parameters—baud rate, data bits, parity and stop bits—within the operating system or application to match the connected device. Verify communication using terminal software or diagnostic tools.

Usage recommendations

For stable operation, use quality shielded RS-232 cables and ensure correct grounding between connected equipment. Match baud rate and data bit settings exactly to the peripheral device to avoid framing errors. In environments with electrical noise, shorter cable runs and ferrite cores can improve signal integrity. Follow the host system and card manufacturer instructions for driver installation and updates to maintain compatibility.
