The new ESU2-400 from Quatech is a high speed USB 2.0 serial adapter which gives your laptop or workstation the ability to communicate between a USB (Universal Serial Bus) port and up to eight serial peripherals. It adds the COM port(s) via its USB connection and is compatible with new and legacy serial devices. Any application which works with an onboard serial port should work with this equipment.

The 400 Series models introduce the software-selectable RS-232/422/485 (Multi-Electrical Interface or MEI). The MEI capability is available on all ports at the click of a mouse. LEDs visually tell you which ports are using which protocol, so go ahead, mix and match.

The USB 2.0 Serial Adapters are the ideal solution for a variety of industries and applications including banking, retail and industrial automation where PCs have a significantly shorter lifecycle than the peripherals that use them. Support is provided for Windows 2000/XP/VISTA & Linux.

USB Serial Adapters vs. USB Serial Cables

Not all USB to serial converters are not the same. There are a number of inexpensive cables on the market that perform USB to RS-232 serial conversion. While these may seem like an economical choice, they are often poor choices for all but the simplest of applications. Many customers who purchase Quatech USB to serial adapters do so after unsuccessful attempts to use these RS-232 converter cables. The reason these cables fail are varied but the most common is that they lack the advanced functionality built into the Quatech adapters.

For example. most adapter cables have very small data buffers and no IRQ support. Quatech USB to serial adapters use 16550 UARTs with 1024-byte transmit and receive FIFOs for each port. This means that applications at very high data rates are easily handled in heavy multitasking environments. In addition, Quatech provides sophisticated drivers for its adapters that enable extensive system configuration options from setting data rates and controlling clocking to setting parity bits and flow control. With these options available, even the most sophisticated application software can address RS-232 serial ports enabled by Quatech adapters exactly as they would a standard COM port.
