## Summary description

The StarTech 2-Port Serial PCIe Card supports RS232, RS422, and RS485 communication with a PCIe interface and a baud rate of 921.6 Kbit/s. It is compatible with Windows and Linux operating systems, includes low-profile brackets for versatile installation, and features Level-4 ESD protection, making it ideal for industrial applications that require reliable serial communication.

## Long description

Add two DB9 serial ports to a desktop or small form factor (SFF) system with the StarTech 2-Port Serial PCIe Card 2S232422485-PC-CARD. The card installs in a PCIe x1 slot and provides two independently configurable DB9 ports that support RS-232, RS-422 and 2/4-wire RS-485 standards for communication with legacy and industrial serial devices. It includes LED activity indicators per port, configurable power on pin 9, and low-profile brackets for flexible installation.
Advantages
The card offers per-port configuration via on-board DIP switches so each DB9 connector can be set to RS-232, RS-422 or RS-485 modes. Configurable external power over pin 9 provides 12V (1.5A per port), 5V (1.5A per port) or no power (RI) selectable by jumpers. LEDs give real-time port activity feedback, and Level-4 ESD protection improves reliability in industrial environments. Compatible with Windows and Linux, the adapter supports a high baud rate (up to 921.6 Kbit/s) and helps maintain legacy device connectivity without system replacements.
Suitable for
Point-of-sale terminals and kiosks
PLC and factory control/automation systems
Scientific sensors and measurement instruments
Medical equipment and laboratory devices
Scanners, oscilloscopes and other serial peripherals

How to use
Install the card into an available PCIe x1 slot in your desktop or SFF system following standard ESD precautions. Select the required serial mode for each DB9 port using the on-board DIP switches and set the external power option using the jumpers if your peripheral requires 5V or 12V on pin 9. Secure the card with the appropriate bracket (standard or low-profile) and connect serial devices using DB9 cables. Install drivers if required for your operating system (Windows or Linux) and verify port activity via the LED indicators.
Usage recommendations
For stable operation in industrial environments, use shielded DB9 cables, enable the appropriate RS-422/RS-485 termination and grounding practices for long cable runs, and observe the card's power jumper settings to match peripheral requirements. Ensure drivers are current for your OS to achieve the rated baud performance.
