Interface Card EXSYS EX-45354 Internal Serial

The EXSYS EX-45354 internal serial interface card is a reliable hardware solution designed to provide stable wired serial connectivity via a PCIe host interface. Featuring RS-422 and RS-485 serial outputs, this expansion card is built to handle robust data communication in various professional and industrial environments. It measures 192 mm in width and 66 mm in depth, with a weight of 500 grams, ensuring a standard fit for compatible computer systems. Certified with CE and FCC standards, the card meets recognized regulatory requirements for quality and safety.

Advantages

The interface card offers high flexibility through selectable signal modes including 4-wire RS-422 full-duplex and 2-wire RS-485 half-duplex configurations. Integration is supported by a FIFO buffer with 16C950 and 128 bytes to help manage data flow efficiently. System integration is further streamlined with BIOS-managed I/O addresses and interrupt settings featuring IRQ sharing capabilities. Additionally, the inclusion of an enable and disable terminator for 120 Ohm resistance helps maintain signal integrity across longer cable runs.

Suitable for

• Connecting industrial automation machinery
• Integrating legacy serial devices into modern PC systems
• Setting up reliable wired data communication networks
• Managing secure serial data transfer in professional workstations

When it may not be suitable

How to use

To install the card, power down the computer, disconnect it from the power source, and open the system chassis. Insert the card firmly into an available PCIe slot and secure it to the chassis. Once the computer is powered back on, configure the I/O addresses and interrupt settings through the system BIOS as needed. Install any required drivers for the operating system to establish communication with connected serial devices.

What to consider before purchase

• Verify that your computer system has an available PCIe slot and sufficient physical space inside the case.
• Check compatibility with your operating system for driver availability.
• Confirm that your external devices require RS-422 or RS-485 serial interfaces.

Usage recommendations

Ensure that the computer is completely powered off and disconnected from the electrical mains before installing or removing the interface card. Properly configure the 120 Ohm terminator settings based on your network layout to maintain reliable data transmission.
