Review on Galvanically Isolated RS422/485 PCI Card With 4 Ports And Quadplex Cable (HD44M-DB9M-4) - Softio LF545KB by Aaron Wood

The Softio LF545KB is a galvanically isolated RS422/485 PCI card with 4 ports and a quadplex cable. The card provides an excellent solution for users who need multiple serial connections on their computer. The galvanic isolation ensures that there is no electrical connection between the computer and the connected devices, protecting them from electrical interference. The card comes with a quadplex cable that has four DB9 male connectors, allowing users to connect up to four devices to the card. The quadplex cable is a convenient solution for users who need to connect multiple devices but don't want to clutter their workspace with multiple cables. The Softio LF545KB card supports data transfer rates of up to 115.2 kbps, making it suitable for most applications. It also supports automatic data direction control, which allows for the easy handling of half-duplex RS485 communication. However, the installation process for the card can be a bit cumbersome. The card requires the installation of drivers before it can be used, and the drivers can be difficult to find on the Softio website. Additionally, the card is not compatible with all operating systems, so users should check the specification sheet before purchasing. Overall, the Softio LF545KB is a reliable and efficient solution for users who need multiple serial connections on their computer. The galvanic isolation and quadplex cable are both convenient features, and the data transfer rates are suitable for most applications. However, the installation process can be a bit of a hassle, and compatibility issues may arise with certain operating systems.
