INTRODUCTION
The PCIe-400 and PCIe-400LP PCI Express 4-port serial I/O cards are plug and play high-
speed serial I/O expansion cards for the PCI Express bus. Connecting to a PCI Express
bus on your computer, the PCI Express 4-port serial I/O card instantly adds four RS-
232 serial I/O communication ports to your system. The PCI Express 4-port serial I/O
cards are designed to utilize the Exar XR17V354 PCI Express to UART chip. The PCIe-
400 & PCIe-400LP support high-speed data rate up to 921.6kbps. Each serial port is
fully compatible with 16C550 UART, with enhanced feature of 256 bytes TX and RX
FIFO buffer for higher performance.
The PCI Express 4-port serial I/O card is an advanced and high efficient solution for
serial data communication and industrial automation applications.

INSTALLATION
Windows 8.1/8/7 32-bit & 64-bit Drivers Installation
To install the Windows driver from Device Manager for PCI Express 4-port industrial
serial I/O card, please follow the steps below:
1. Switch off the computer.
2. Insert PCI Express industrial serial I/O card into a free PCI Express Bus slot.
3. Switch on the computer and start Windows OS.
4. Windows OS will automatically detect the PCI Express I/O Card.
5. Press “START” button and select “Control Panel”.

8
6. Select “Hardware and Sound”.
