Interface Card EXSYS EX-45362 Internal Serial

The EXSYS EX-45362 Internal Serial Interface Card is a reliable hardware solution designed to expand the communication capabilities of your computer system. Featuring a PCIe host interface and dual serial output ports, this adapter provides instant COM port expansion for PCs, thin clients, and servers. Each port can be independently configured for RS-232, RS-422, or RS-485 protocols, offering versatile connectivity options for industrial and commercial environments. The card incorporates 16C550-type UART compatibility and supports advanced features such as the unique ATTATM hardware for RS-485 Auto Transmitter turn around.

Advantages

This internal serial card delivers high-performance data transmission with flexible configuration options to suit diverse operational requirements. Fully compatible with PCI Plug-and-Play standards, it eliminates manual IRQ and I/O address configuration issues during installation. The inclusion of power over system capabilities allows you to supply +5V or +12V via pin 9 of the male connector, making it particularly advantageous for POS systems. Additionally, the compact low-profile design combined with the included low-profile bracket ensures seamless integration into both standard and space-constrained computer cases.

Suitable for

• Expanding serial communication ports on desktop PCs and servers
• Connecting legacy hardware using RS-232, RS-422, or RS-485 interfaces
• Integrating POS systems that require power delivery through the serial connector
• Upgrading thin clients and compact computer systems with low-profile expansion needs

When it may not be suitable

This interface card is not designed for systems lacking an available PCIe slot or devices that require non-serial expansions. It may also be unnecessary for modern consumer setups that do not utilize industrial or legacy serial communication protocols.

How to use

To install the EXSYS EX-45362 interface card, power down your computer and disconnect it from the electrical outlet. Open the computer case and locate an available PCIe slot. Remove the slot cover from the back of the case. If you are using a compact case, replace the standard bracket on the card with the included low-profile bracket. Carefully insert the card into the PCIe slot until it is firmly seated, then secure it to the chassis. Close the computer case, reconnect the power, and start the system. The operating system should automatically detect the hardware using Plug-and-Play technology. Connect your serial cables to the appropriate ports and configure the protocol settings as required by your peripheral devices.

What to consider before purchase

• Verify that your computer motherboard has an available PCIe slot
• Check the physical space inside your computer case to ensure compatibility with standard or low-profile dimensions
• Confirm the communication protocol requirements of your peripheral devices
• Ensure your operating system supports standard PCI serial expansion drivers

Usage recommendations: Install the card in an environment where operating temperatures remain within 0 to 55 °C to ensure stable performance. Always ground yourself properly before handling internal computer components to prevent electrostatic discharge damage.
