## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Outstanding product, worked where others failed!
  

*by K***R on Reviewed in the United States on October 28, 2012*

I purchased this card, after going through a huge amount of frustration with an external RS232/RS485 converter, for PTZ control of our security cameras. It shows up as a couple of COM ports under Windows server 2003, and works very well indeed.StarTech's definitely got a winner with this one. If you have need for RS485 ports, it won't get much better than this.

### ⭐⭐⭐⭐
