Add two RS-232 RS-422 or RS-485-capable DB9 Serial Ports to a desktop computer via PCIe x1 Expansion Card
Add serial communication support to a desktop computer or Small Form Factor (SFF) system using this 2-Port Serial PCI Express Card. The two DB9 ports can be independently configured to support RS-232 RS-422 and 2/4-wire RS-485 standards for communication with compliant serial peripheral devices.
Per-Port Serial Configuration
This PCIe Serial Card is equipped with on-board DIP switches enabling 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 features three power modes that are configurable via on-board jumpers including 12V (1.5A per port) 5V (1.5A per port) or no power (RI) over pin 9.
Legacy Connectivity
This serial card enables the continued use of legacy serial devices preventing down time and avoiding 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).
