The development of the Universal Serial Bus system effectively removed the complication from adding peripheral devices to your PC. The standard enabled PC users to simply plug in new devices, without ever seeing the inside of their computer. With our USB-to-Serial device, it allows multiple serial to be added to your computer with ease.
The grandfather of the expansion bus, the Industry Standard Architecture (ISA) can still be found in some very old computer systems today. Though the ISA bus is already phased out from commercial PC systems, it is still used in some industrial PC-based systems. To address the needs of the industrial market, we continue to provide ISA serial to support such legacy applications.
