Why Use Serial Cards in Modern Systems?
Many new PCs and servers no longer include native serial ports. Expansion cards restore this capability, allowing engineers to continue using equipment that depends on RS-232, RS-422 or RS-485 connections.

How Do Adaptors Add Flexibility?
Adaptors provide quick conversion between different serial standards or between USB and serial. This makes it simple to connect a variety of legacy devices without needing to reconfigure or replace existing hardware.

What Benefits Do Industrial Models Offer?
Compared to office-grade products, industrial cards and adaptors feature stronger isolation, extended temperature support and reinforced components. These features ensure long service life in demanding environments such as manufacturing and utilities.
