 +==== How to connect USB only equipped PC to Serial Console of DNS-300 ====
 +It's the easyest way to to use Serial Console of DNS-300 and can be recommended to use for any unprofessionals (but you still need to remove warranty label from DNS-300).
  
 +First: you need to purchase USB to serial converter with TTL levels. Good one is: **TTL-232R-3V3** from FTDIChip company http://​www.ftdichip.com/​Products/​EvaluationKits/​TTL-232R-3V3.htm. For example I bought it in St.Petersburg,​ Russia from www.efo.ru company by $23 without any problem. Also you'll need to buy 5x1 pin connector.
 +Second: You need to modify FTDI serial connector to make it compatible with DLink serial connector. ​
 +Original FTDI connector is:
 +| 1 |  black  |  GND  |
 +| 2 |  brown  |  CTS#  |
 +| 3 |  red  |  VCC  |
 +| 4 |  orange ​ |  TXD  |
 +| 5 |  yellow ​ |  RXD  |
 +| 6 |  green  |  RTS#  |
 +Take out 3 pins (black, yellow and orange) from 6x1 pin FTDI plastic connector and put them to empty plastic 5x1 pin connector by following table:
 +| 1 |  orange ​ |
 +| 2 |  black  |
 +| 3 |  x  |
 +| 4 |  x  |
 +| 5 |  yellow ​ |
 +
 +Thats all. Now you can connect this cable to USB port of your PC and to serial console of DNS-300. Pin 1 (orange) should be close to the battery of DNS-300. Check picture:\\ {{:​hardware:​dns-300_serial_connector.jpg?​200|Serial Connector}}
 +
 +**Serial settings:** 19200, 8 bit, no parity, no hardware sync.
