Overview

About the StarTech.com PCI Serial Parallel Combo Card with Dual Serial RS232 Ports (DB9) & 1x Parallel Port (DB25), PCI Adapter Expansion Card

View user manual

This PCI 1x Parallel and 2x Serial Combo Card installs into a single PCI slot in your computer (occupying 2 to 3 expansion slots, depending on profile), and adds a DB25 IEEE 1284 parallel port and two DB9 RS 232 serial ports to your system.

Adds an LPT Parallel Port

The controller card features an Asix MCS9865 chip and enables you to connect a DB25 parallel device to your desktop computer. The parallel port is ideal for connecting printers, scanners, plotters, point-of-sale terminals, PLCs, scientific sensors, medical equipment or oscilloscopes. The parallel (LPT) port supports SPP/Byte/Nibble/ECP/EPP modes and IEEE 1284 for speeds up to 1.5Mbps.

Adds a COM Serial Port

The Asix MCS9865 chip also enables you to connect two DB9 devices using the same controller card, compatible with industry standard 16C550 UART. The serial ports are ideal for connecting point of sale terminals, serial printers, PLCs, control/automation in factories, scientific sensors, medical equipment, scanners and oscilloscopes. The serial (COM) ports support bi-directional RS232 speeds up to 115.2Kbps per port, available 256 byte FIFO buffer & 9th data bit.

Wide Installation Compatibility

With broad OS support, including for Windows (7 and up), and Linux (2.6.x to 5.x LTS versions only), this PCI serial/parallel card is easy to integrate into mixed environments. The card comes pre-configured with 2x full-profile brackets, and includes optional 3x low-profile brackets, so installation is easy regardless of the case form factor.
