Product information

Description

The Interface Card Exsys EX-42378 is an internal serial interface card utilizing a PCI host interface. Designed to provide instant COM port expansion via the PCI or PCI-X bus, this I/O adapter features eight high-performance 16C1050-type UART-compatible serial ports supporting RS-232, RS-422, and RS-485 serial types. It is equipped with a 256-byte FIFO buffer to ensure reliable data transmission and features unique ATTA hardware for RS-485 Auto Transceiver turn-around support. Additionally, the card can provide +5V and +12V power via pin 9 of the male connector for POS systems.

Advantages

The Exsys EX-42378 internal serial interface card offers seamless integration with personal computers, thin clients, and servers requiring reliable serial communication. Fully PCI Plug-and-Play compatible, the card eliminates traditional configuration issues related to IRQ and I/O addresses. Its robust hardware design operates efficiently across a wide temperature range from -40 to 75 °C, making it suitable for demanding industrial and commercial environments. The inclusion of power over system capabilities adds versatility for connected peripheral hardware.

Suitable for

Expanding COM ports on desktop PCs, thin clients, and servers
Connecting RS-232, RS-422, and RS-485 serial devices
POS system setups requiring power delivery through the serial connector
Industrial automation and communication tasks in wide temperature ranges

When it may not be suitable

This internal card is not suitable for computer systems that lack an available PCI or PCI-X slot, such as modern motherboards equipped exclusively with PCIe slots. It is also not designed for non-serial peripheral connections or external USB-based serial setups without appropriate conversion hardware.

Key specifications

Host interface: PCI
Output interface: Serial (RS-232, RS-422, RS-485)
UART type: 16C1050 compatible
FIFO buffer: 256 bytes
Operating temperature range: -40 to 75 °C
Operating humidity range: 5 to 95%
Dimensions: 150 mm width, 60 mm depth
Weight: 1.2 kg

How to use

To install the Exsys EX-42378 interface card, ensure the computer system is powered off and unplugged. Open the chassis and insert the card firmly into an available PCI or PCI-X expansion slot, securing the bracket to the computer case. Close the chassis, reconnect the power, and turn on the system. The operating system will automatically detect the hardware using Plug-and-Play functionality. Install the appropriate drivers compatible with your Windows version to configure the serial ports and connect your RS-232, RS-422, or RS-485 devices as required.

What to consider before purchase

Verify that your computer system has an available PCI or PCI-X slot rather than PCIe
Check compatibility with your specific Windows operating system version
Confirm the physical dimensions fit inside your computer chassis
Determine if your peripheral devices require RS-232, RS-422, or RS-485 protocols

Usage recommendations

Ensure proper grounding precautions are taken during internal installation to protect sensitive electronic components, and verify driver compatibility prior to deploying the serial interface card in critical operating environments.
