Product information

Description

Add four DB9 serial ports to a desktop or small form factor (SFF) system with the 4-Port Serial PCIe Card by StarTech.com (PS74ADF-SERIAL-CARD). The card provides flexible serial connectivity by allowing each DB9 port to be independently configured for RS-232, RS-422, or 2/4-wire RS-485 standards. It includes LED activity indicators per port and a low-profile form factor suitable for many PCIe x1 slots.

Advantages

The card supports per-port serial configuration via on-board DIP switches, enabling mixed-mode installations. Configurable external power over pin 9 (12V at 1.5A per port, 5V at 1.5A per port, or no power/RI) is selectable with jumpers. LEDs provide real-time port activity monitoring. The adapter is compatible with common operating systems such as Windows and Linux and includes ESD protection and support for high baud rates to ensure reliable communication with serial peripherals.

Suitable for

Point-of-sale terminals and barcode scanners
PLC, factory control and industrial automation systems
Laboratory instruments, scientific sensors, and oscilloscopes
Medical equipment and diagnostic devices
Legacy serial devices requiring continued connectivity in modern systems

Power on pin 9: configurable 12V (1.5A/port), 5V (1.5A/port), or no power (RI)
Indicators: per-port LED activity indicators
Form factor: low-profile compatible
Product colour: Black
Weight: 0.06 kg
Compatibility: Windows and Linux

How to use

Install the card into an available PCIe x1 slot in the desktop or SFF system following standard ESD precautions. Set the DIP switches on the board to select the desired mode (RS-232, RS-422, or RS-485) for each DB9 port. Configure the power jumper to supply 12V, 5V, or no power on pin 9 as required by your connected devices. Secure the card with the appropriate bracket (low-profile or standard) and connect serial peripherals using DB9 cables. Install any required drivers for your operating system (Windows or Linux) and verify port activity using the LED indicators.

Usage recommendations

Use shielded DB9 cables for improved signal integrity and enable the appropriate termination and biasing when using RS-422/RS-485 networks. Confirm device voltage and power requirements before enabling pin 9 power to prevent damage. For mixed serial environments, verify DIP switch settings per port and test communication at the intended baud rate prior to deployment.
