2 Port PCI RS422/485 Serial Adapter Card

PCI2S4851050 PCI Serial Adapter Card

The PCI2S4851050 2-Port PCI Serial Adapter Card (RS422/RS485) with 161050 UART adds two DB9 RS422/RS485 serial ports, using a single PCI expansion slot.

The PCI serial card offers a high performance 16C1050 UART and supports both 2-wire and 4-wire RS485 modes. The card delivers an efficient single-chip design and a large 256-byte transit/receive FIFO buffer that work together to provide high-speed serial communication while reducing the overall load on the system CPU.

With the included standard and low profile/half-height brackets, this PCI serial expansion card suits a broad range of system form factors, and is a perfect addition for connecting RS422/485 serial devices to a host computer. For added versatility, the RS422/RS485 adapter is able to accommodate 3.3 or 5V PCI/PCI-X slots.

Backed by a StarTech.com lifetime warranty and free lifetime technical support.

FAQ

Will this PCI card fit into my PCI-X slot?

It depends on your motherboard. This PCI card is keyed for 5V PCI and PCI-X slots. If your motherboard's PCI or PCI-X slots are keyed for 5V, this will work. If it is keyed for 3.3V, it will not. You can tell which your motherboard is keyed for by the location of the notch on the slot. To confirm whether this PCI card will fit into your PCI-X slot, refer to your motherboard's documentation.
