## Summary description

The DeLOCK PCI Express x1 Card provides 2 x Serial RS-422/485 ports with 15 kV ESD protection. It features a PCIe 2.0 host interface and supports FIFO of 256 B. Configurable data bits (5, 6, 7, 8) and stop bits (1, 1.5, 2) make it versatile for various applications. Ideal for industrial use, it ensures reliable communication with robust protection against electrical surges.

## Long description

The DeLOCK PCI Express x1 Card to 2 x Serial RS-422/485 adds two external serial ports (RS-422/RS-485) to a PC. It supports PCIe 2.0 host interface, 15 kV ESD protection and a 256 B FIFO buffer. The card is supplied with a standard and a low profile bracket for installation in desktop or Mini-PC systems.
Advantages
The adapter supports both RS-422 and RS-485 protocols with selectable 2- and 4-wire operation and configurable data and stop bits. Integrated terminating resistors can be enabled to reduce signal reflections. Jumper-selectable modes include Auto Detect, RS-422, RS-485 4-wire full duplex and RS-485 2-wire half duplex. The PCIe x1 interface provides compatibility with PCIe slots while the FIFO and ESD protection improve communication reliability in industrial environments.
Suitable for
 Industrial automation and control equipment
 Point-of-sale (POS) systems and barcode scanners
 Protocol converters and IoT or infrared devices
 Systems requiring robust serial communication with surge protection

How to use
Install the card into an available PCIe x1 slot (or compatible PCIe slot) on the host PC and secure the appropriate bracket for the chassis. Connect external RS-422 or RS-485 devices to the terminal connectors. Configure the required mode and termination via the on-board jumpers (choose Auto Detect, RS-422, RS-485 4-wire or RS-485 2-wire) and set data bits and stop bits according to the peripheral device specifications.
Usage recommendations
For reliable serial communication, enable terminating resistors at the ends of long transmission lines and verify wiring for correct 2- or 4-wire configuration. Use shielded cabling and proper grounding in electrically noisy or industrial environments. Check device manuals for matching data and stop bit settings.
