Syba Serial Port Cards Editorial Review
The Syba Single Port RS-232 DB9 Serial PCI-Express 2.0 x1 Card is a reliable and functional option for those in need of a serial port on their computer. It is compatible with Windows XP, 7, 8, and 8.1, making it versatile for various operating systems. The card uses the MCS9922 chipset and supports RS-232 connections. Despite some initial confusion regarding compatibility with Mac Pro towers and Windows Server 2003, it has been confirmed that there are no MAC drivers available for the device. However, it works well with Windows operating systems, as mentioned by multiple customers. Feedback on the card's performance is mixed. Some customers report that it works great and solves their connection needs, such as connecting to older ski race timing equipment or programming radio scanners. They also mention that it is easy to configure and the drivers install without any issues on Windows 10. However, others have experienced issues, including receiving a dead on arrival card, encountering unreliable and non-existent tech support from Syba, and the card stopping working after a while. Overall, the Syba Single Port RS-232 DB9 Serial PCI-Express 2.0 x1 Card can be a useful addition to a computer system for those in need of a serial port.
