Startech 2-Port Serial PCIe Card Dual-Port PCI Express to RS232/RS422/RS485 DB9 2S232422485-PC-CARD

Add two RS-232, RS-422, or RS-485-capable DB9 Serial Ports to a desktop computer via PCIe x1 Expansion CardAdd 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 ConfigurationThis 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 PowerThe 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 ConnectivityThis 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).The StarTech.com Advantage

Features


2-PORT PCIE SERIAL CARD: On-board DIP switches allow each DB9 serial port to operate in its own independent mode, enabling the connection of RS-232, RS-422, and RS-485 devices; LED indicators to monitor data transmit/receive status


CONFIGURABLE POWER: Dual-Port PCI Express Serial Adapter Card features configurable power of 12V (1.5A per port), 5V (1.5A per port), or no power (RI) over pin 9 via auxiliary SATA power; Per-Port power modes are individually configurable via jumpers


APPLICATIONS: Ideal for desktops and servers, with a wide range of uses such as point-of-sale terminals, PLCs, factory control and automation, scientific sensors, medical equipment, scanners, and oscilloscopes; DB9 ports work with screw-locking cables


STANDARD & LOW PROFILE BRACKETS: TAA-Compliant Serial Card is equipped with a standard profile bracket (pre-installed), and includes two low-profile brackets for compatibility with small form factor desktops/servers
