Add serial ports to PCI systems

The Syba SD-PCI-2S adds two DB9 serial connectors to any computer with an available PCI slot. It is built for users who still rely on legacy serial equipment such as industrial controllers, barcode scanners or older networking gear. The card uses the NM9835CV controller and is supplied with a driver disc and manual.

Suits legacy hardware.

This card suits technicians maintaining older Windows or Linux machines that lack native serial ports. It supports Windows 98SE through XP, NT 4.0, Linux and DOS. Builders who need USB, Ethernet or faster data rates should look at a different interface card.

Two DB9 ports with 16C550-compatible UART

The card provides two external DB9 ports driven by a 16C550-compatible UART with 16-byte FIFO buffers. It complies with PCI Specification Revision 2.1 and delivers data rates up to 1 Mbps.

Questions about this item

What limits the sustained data rate of the NM9835CV controller on this card?

The NM9835CV chipset provides fast data rates up to 1Mbps with a 16 byte transmit-receive FIFO compatible with the standard 16C550 UART.

How much power does the SD-PCI-2S draw and does it add heat or noise during all-day operation?

The card draws power from the PCI slot with no fan or external connector, so it runs silently and adds negligible heat inside the case.

Which operating system must already be installed for the Plug & Play installation to work automatically?

Supported systems include Windows 98SE, ME, 2000, XP, NT4.0, Linux and DOS, each automatically selecting IRQ and I/O address.
