StarTech.com 2S232422485-PC-CARD Internal Interface Adapter Card

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

Add serial communication support to a desktop computer or a small form factor (SFF) system, using this 2-port PCI Express serial card. The two 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, allowing each DB9 serial port to operate in RS-232, RS-422, and/or RS-485 mode(s). The card features per-port LED indicators, providing real-time port activity monitoring.

Configurable External SATA Power

The PCI Express serial adapter card includes three power modes configurable 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 continued use of legacy serial devices, avoiding downtime and costly upgrades. The 2-port PCIe serial card is an ideal system upgrade for a wide range of applications (e.g., point-of-sale terminals, PLCs, factory control and automation, scientific sensors, medical equipment, scanners, and oscilloscopes)
