StarTech.com PS74ADF-SERIAL-CARD interface card and adapter Internal

Add four RS-232, RS-422, or RS-485 DB9 serial ports to a desktop computer using a PCIe x1 expansion card

Add serial communication support to a desktop computer or small form factor (SFF) system using this 4-port serial PCI Express card. The four DB9 ports can be configured independently to support RS-232, RS-422, and 2/4-wire RS-485 standards for communication with compatible serial peripheral devices.

Per-Port Serial Configuration

This PCIe serial card is equipped with onboard DIP switches that allow each DB9 serial port to operate in RS-232, RS-422, and/or RS-485 mode(s). The card features LED indicators per port, providing real-time monitoring of port activity.

Configurable External SATA Power

The PCI Express serial adapter card includes three configurable power modes via onboard jumpers, including 12V (1.5A per port), 5V (1.5A per port), or no power (RI), via pin 9.

Legacy Connectivity

This serial card allows you to continue using legacy serial devices, avoiding downtime and costly upgrades. The 4-port PCIe serial card is an ideal system upgrade for a wide range of applications (e.g., POS terminals, PLCs, factory control and automation, scientific sensors, medical equipment, scanners, and oscilloscopes)
