Quatech's serial USB adapters require the Windows 98/Me/XP/2000/NT4
operating system and an IBM or IBM-compatible PC with a standard
two
USB port or an add-in USB host adapter. Contact our sales
department for details on current software offerings. Most device
drivers are available for download from the Quatech World Wide Web
site at http://www.quatech.com/.
Quatech offers an IND option, or surge-suppression board upgrade, to
provide improved performance and industrial-grade reliability.
The IND option provides essential protection for reliable use in an
industrial environment. Each communication line has a surge
suppressor capable of sustaining up to 40-A, 20- s peak transient
surges, a clamping voltage of 30 V (15.1 V for 200/300 units), and a
peak energy dissipation of 0.1 Joules.
