The DB9 pin Serial RS232 plus DC power connector allows you to bring serial connectivity and power to another device. The way this cable works is that a DB9 serial connection does not use all its 9 pins in the interface with an RS232 cable. Therefore, we designed this cable to piggy-back a power supply so that those previously unused pins now provide 5V power.
