Support for both 3.3V and 5V motherboards offers broad compatibility with various system boards. Additionally, the bundled octopus cable and low-profile bracket simplify installation in standard and compact computer chassis, while the operating temperature range from 0 to 55 degrees Celsius ensures dependable functioning across different settings.

Suitable for

• Connecting industrial serial devices to desktop computer systems
• Upgrading older workstations with RS-422 and RS-485 serial ports
• Integrating specialized hardware requiring PCI slot communication
• Setting up stable wired data transmission lines for automation equipment

When it may not be suitable
This interface card is not compatible with modern PCI Express (PCIe) slots, as it strictly requires a traditional PCI or PCI-X slot. It will also not function in computer systems running operating systems other than the supported Windows versions, such as contemporary Linux distributions or newer Windows editions, unless proper legacy drivers are successfully configured.

• Chip-set: Oxford
• Buffers: 2 x FIFO 16C950
• Operating temperature range: 0 to 55 °C
• Operating humidity range: 5 to 95 percent
• Supported operating systems: Windows 2000, Windows 7 Ultimate, Windows XP

How to use
Power down the computer system, unplug the power cord, and open the computer case to access the internal components. Locate an available PCI slot on the motherboard, remove the corresponding slot cover from the chassis, and gently insert the Exsys EX-42372 interface card until it is firmly seated. Secure the bracket to the chassis, connect the included octopus cable to the card, and close the computer case. Power on the system and install the appropriate drivers for your Windows operating system to begin connecting your serial devices.

What to consider before purchase

• Verify that your motherboard has an available and compatible PCI or PCI-X slot
• Confirm that your computer runs a compatible operating system such as Windows XP, Windows 2000, or Windows 7 Ultimate
• Check whether your peripheral devices utilize RS-422 or RS-485 serial connections
• Ensure the physical dimensions of the low-profile bracket or standard bracket match your computer chassis

Usage recommendations
Ensure the computer system is completely disconnected from power before installing or removing the interface card to prevent electrical damage. Handle the card by its edges to avoid touching sensitive electronic components and consult system documentation to verify voltage compatibility with 3.3V and 5V PCI slots.
