PCIe Serial Cards

RS-232, RS-422 and RS-485 Boards for PCI Express

They don’t make them like they used to. In technology, this truth forces us to use old devices alongside new components. Enabling them to communicate in harmony is one of the perpetual challenges of the job. If you have legacy devices that can’t be replaced, keep them in form by utilizing PCI Express (PCIe) RS-232/422/485 serial boards from Antaira Technologies. Their suite of options – number of ports, surge protection and low profile height - allows you to add serial ports to any server or desktop in short order. These serial boards are a great way to keep old printers, plotters, instruments and other serial devices attached to the latest computers.

A Card for Every Purpose

Legacy devices are as diverse as modern counterparts, so you won’t find one universal solution. Instead, we can offer a precise card for any needed function. Consider the MSC-202AL1. This low-profile card adds two RS-232 serial expansion ports. Designed for PCIe, it is backwards compatible with PCI applications and supports data rates up to 250MB/s. It offers power over 9-pin and has drivers for both Windows and Linux.


The MSC-202ALP1 expands 2 serial ports and 1 parallel port. It can provide 5V or 12V power over the ports and is scalable and backwards compatible. The low-profile form factor enables it to more freely fit in a wider range of racks and servers, making it an easy choice for many applications.

Supporting Networks Through Proper Planning

PCIe RS-232, RS-422 and RS-485 serial boards will keep your legacy serial devices in service. The best way to optimize your network with as little downtime as possible is through careful planning. A chat with one of our experts can help you achieve that by informing you of the latest and most reliable technology options available.
