Overview

The PS74ADF-SERIAL-CARD is a PCI Express x1 expansion card that provides two high-performance serial ports supporting RS-232, RS-422, and RS-485 protocols. It is designed for industrial environments, featuring LED indicators for port activity and on-board DIP switches for hardware configuration. The card ensures consistent device management through COM retention and offers configurable power output via jumpers.

Why Choose This Part

This card offers exceptional versatility by supporting RS-232, RS-422, and RS-485 on a single PCIe x1 footprint. The inclusion of COM retention prevents software configuration issues after reboots, while the LED indicators provide immediate visual diagnostics for communication status.

Applications

Industrial Automation
Connecting PLCs, motor drives, and industrial sensors that require robust RS-485 or RS-422 differential signaling.
Legacy Peripheral Support
Integrating RS-232 based barcode scanners, receipt printers, or satellite receivers into modern PCIe-equipped workstations.
SCADA Systems
Acting as a communication hub for supervisory control and data acquisition in utility or manufacturing environments.
Laboratory Instrumentation
Interfacing with scientific equipment that utilizes serial communication for data logging and remote control.

Key Specifications

Type RS-232
Interface PCI Express
Number of Ports 2

Getting Started

Install the card into any available PCIe x1, x4, x8, or x16 slot and configure the on-board DIP switches for the desired serial protocol (RS-232/422/485). Use the provided jumpers to enable or disable power output on pin 9 if your peripheral requires external power. Drivers are typically required for Windows or Linux environments to recognize the four internal UARTs.
