## Long description

The Interface Card Exsys EX-42034IS is an internal serial interface card designed for standard PCI slots, allowing you to expand your PC, small workstation, or server with four additional high-performance serial ports. Operating via the PCI or PCI-X bus, this card features UART 16C550 outputs and provides robust protection mechanisms including 15KV ESD surge protection and 2.5KV optical isolation to ensure stable data transmission in demanding environments. Each of the four ports can be individually configured, offering versatile connectivity for multiple serial communication protocols.
Advantages
The Exsys EX-42034IS serial interface card delivers exceptional flexibility by supporting RS-232, RS-422, and RS-485 serial interfaces with individually configurable ports to match your specific system requirements. Built with reliable hardware features like a 16-byte FIFO buffer and the ATTATM Auto RS-485 transmitter feature, it ensures smooth and efficient data handling. Furthermore, the integration of advanced safety measures such as 15KV ESD surge protection and 2.5KV optical isolation significantly enhances equipment longevity and operational reliability in industrial and commercial settings, while the fully plug-and-play compatible design ensures straightforward installation without complex driver configuration hassles.
Suitable for
Expanding serial connectivity on desktop PCs, small workstations, and servers
Connecting legacy industrial automation and control equipment
Point of sale (POS) terminal setups requiring reliable serial communication
Multi-protocol data acquisition systems using RS-232, RS-422, or RS-485 interfaces
This internal interface card may not be suitable for modern computer systems that lack traditional PCI or PCI-X expansion slots, as it cannot be used with PCIe-only motherboards. Additionally, it is not designed for consumer-grade multimedia tasks or general peripheral connections that require high-speed USB or network interfaces.
Key specifications
Bus interface: PCI and PCI-X compatible
Supported serial standards: RS-232, RS-422, RS-485
Output ports: 4 high-performance UART 16C550 serial outputs
Buffer: 16-byte FIFO
Protection: 15KV ESD surge protection and 2.5KV optical isolation
Data configuration: 7 or 8 data bits, 1, 1.5, or 2 stop bits
Output voltage: 5-12 V
Quantity: 2 pieces per pack
To install the interface card, first power off your computer and disconnect it from the electrical outlet. Open the computer case, remove the metal bracket covering an available PCI or PCI-X slot, and carefully insert the card into the slot until it is firmly seated. Secure the mounting bracket to the chassis, close the computer case, reconnect the power, and boot up the system. The operating system should automatically detect the hardware using plug-and-play compatibility, after which you can connect your serial devices to the designated ports.
What to consider before purchase
Verify that your computer motherboard has an available PCI or PCI-X expansion slot
Check whether your peripheral devices utilize RS-232, RS-422, or RS-485 communication protocols
Confirm that your system operating system is compatible with standard multi-port serial expansion cards
Usage recommendations: Ensure proper grounding of your computer system before handling and installing the card to prevent electrostatic discharge damage. Configure each port individually according to the specific protocol requirements of your connected serial devices to ensure optimal communication performance.
