USB 2.0 SER ADPT 8PT RS232/422/485 If speed, expansion and support are what you're looking for in a USB Serial Adapter, think Quatech. You can now broaden the range of external peripherals used on your computer at higher speed rates than the USB 1.1 series, with the introduction of the High Speed USB 2.0 Serial Adapters. The USB 2.0 has more bandwidth that allows higher data rates on the serial ports for more efficiency. The High Speed USB 2.0 Serial Adapter line gives your laptop or workstation the ability to communicate between a USB (Universal Serial Bus) port and up to eight RS-232, RS-422, or RS-485 serial peripherals. It adds the COM port(s) via its USB connection and is compatible with new and legacy RS-232 or RS-232/422/485 devices. 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. Quatech USB Serial Adapters enumerate themselves as standard COM ports that are compatible with all standard RS-232 or RS-232/422/485 devices and software created for them. With the industrial surge suppression "IND" option, you can safeguard the USB Serial Adapter. The "IND" option is ideal for implementing USB-to-serial networks in factories, power plants and other potentially harsh industrial environments. USB 2.0 is fully compatible with USB 1.1 devices. The older devices work with the new bus, and vice versa. The 400 Series models introduce the software-selectable Multi-Electrical Interface. 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.
