There is a need for a quick low cost device to controlling/communicating with the popular low-voltage differential signaling (LVDS). There is a need for transmit only, receive only, and transmit/receive USB devices. The current solution is to buy the NI USB-6501 and build a daughter board with TTL-LVDS ICs on it to interface to digital equipment in the military/defense industry. Lots of time and energy is wasted on designing, building, and cabling boards as as additional interface step, where a simple USB solution could be made available.
