InLine Interface Card 1 Port 25 Pin Parallel + 2 Ports 9 Pin Serial PCIe

The InLine Interface Card 1 Port 25 Pin Parallel + 2 Ports 9 Pin Serial PCIe provides one IEEE1284-compatible parallel port (25-pin) and two RS-232 serial ports (9-pin) on a single PCI Express (1x) card. Based on the ASIX/Moschip MCS9901CV-CC chipset, the card complies with PCI Express Basic Specification Revision 1.0a and supports data throughput up to 2.5 Gb/s on the PCIe link. It is compatible with Windows 2000, Windows XP (32/64 bit), Server 2003, Vista (32/64 bit), Linux, Mac OS and DOS, and may allow installation of multiple cards in one PC.

Advantages

This PCIe interface card combines parallel and serial connectivity on a single low-profile board, using the Moschip MCS9901CV-CC chipset for reliable protocol support. The serial ports implement industry-standard 16C450/16C550-compatible UARTs with on-chip 256-byte FIFOs per port and support data rates up to 250 kb/s (special versions may reach up to 1 Mb/s). The parallel port is IEEE1284 compatible and supports SPP, PS/2, EPP and ECP modes with fast transfers up to 1.5 Mb/s. The card supports common serial formats (5–8 data bits, various parity options, 1 or 2 stop bits) and both hardware and software flow control.

Suitable for

• Adding legacy parallel (25-pin) printer or device connectivity to modern PCIe systems
• Connecting RS-232 serial devices such as modems, industrial controllers, barcode scanners or measurement equipment
• Systems requiring multiple serial/parallel ports where motherboard ports are unavailable

How to use

Power down the PC and insert the card into an available PCIe x1 slot (the card requires two adjacent slot spaces). Secure the bracket and boot the system. Install drivers for your operating system if they are not automatically provided. Connect the 25-pin parallel cable and the 9-pin serial cables to the appropriate ports. Configure serial port parameters (baud rate, data bits, parity, stop bits, flow control) in your operating system or device software to match the connected equipment.

Usage recommendations

For reliable serial communication, set the serial port parameters to match the connected device and enable hardware flow control when supported. If using multiple cards in one system, ensure adequate slot spacing and check driver compatibility for the targeted operating system.
