Main advantages: 
 * The world's only Boston appearance in electron can DB-9/DB-9 three-wire RS-232 to achieve the above optical isolation! 
 * Boss RS-232 supports the most high-speed optical isolation rate of 150Kbps! 
 * Not affect the RS-232 level, can transmit more than 30 meters! 
 * Rate faster, smaller and cooler appearance! No external power supply!
